Problem: Write an article based on this summary: Type this on a new line.

Answer: Before your can run any queries on a specific database, you must select which database. In PHP to do this we use the "mysql_select_db" function, which requires 1 argument. The first argument in the code is required, it is the name of the database to connect to. The second argument I used is not required but good practice; it defines which server connection to use to select the database.

Problem: Write an article based on this summary: Do your research. Get a good guidebook. Understand the basic customs of the area. Learn some basic phrases of the country you are going to. Get a reliable map of the area you are going to. Be aware of common scams in your destination.

Answer: You need to research where you are going, the flight times and prices for airlines, and which documents you need to take with you. Plan out your itinerary carefully. Some cities, like London or Paris, really need a week to see what they have to offer. Travel times also need to be taken into consideration. Traveling by train can take longer than traveling by car. Fodor's, Rick Steves, and the Michelin guides are all excellent places to start. Make sure you have the most up-to-date guide book for the area of the world you intend to visit. Some are updated every year. Others are updated every other year, or every few years. A good guidebook is a $15-20 investment that can save a lot of headache. Don't be afraid to rip it up and staple together only the pieces you need. A well-kept guidebook might make a nice souvenir, but it may not be worth the extra weight of carrying around information that you don't need. Before going on the trip, research what is and is not acceptable in your destination. When you arrive, observe how others act in person. Remember: some things are okay for locals to do, but not for tourists to do. This is just polite. Even if you struggle with it, the locals will appreciate that you've at least tried their language instead of rudely asking "Do you speak English?" (Or whatever your native tongue happens to be.) If you use the native language to ask for something, expect the reply to be in that language and at normal conversational speed which is going to be faster than the audio lessons you learned. This is not to say that you shouldn't learn some basic greetings and questions. You should, however, be ready for the responses. Memorize it and note each of the places you will be visiting. Keep your map safe and dry. If you have access to a laptop or a smartphone (with data), you may not expressly need a physical map but it is still usually smart to carry one as a backup. Examples include the "dropped ring" scam, the "fake petition," and friendship bracelets tied on your wrist by aggressive vendors. Also be aware of other common crimes, especially pickpocketing. TSA approved travel locks and money belts are both helpful, especially in areas where pickpocketing is extremely common. The infamous #64 bus in Rome, for instance, is popular with pickpockets because it's the only bus in Rome that hits all of the popular tourist destinations. It's usually packed with tourists, and thick with thieves. Know what each local coin and bill is worth. For example, in Panama, everything is tied to the US dollar, so money comes in the same size, denomination, and material. In the UK, you'll find 1p, 2p, 5p, 10p, 20p, 50p, 1, and 2 coins, as well as 5, 10, 20, and 50 pound notes. By knowing your denominations and specifying how much you are handing over, you can help avoid another common scam: intentionally incorrect change.

Problem: Write an article based on this summary: Have the disturbed material repaired. Live safely with materials that contain asbestos. Consider asbestos removal.

Answer: Repairs to materials that contain asbestos usually involved either sealing or covering the area to prevent fibers from being released into the air. With such a dangerous carcinogen present, it might seem strange to repair it instead of removing it, but repair is actually the safest option. Removing the materials tends to disturb them more, posing a greater health risk, while repairing the materials to contain the asbestos allows you to live with the materials safely. Repairs should be conducted by a certified professional to ensure they are done properly. In most cases, a special sealant or covering is applied to the area to keep it from breaking down. Floors containing asbestos might be covered with new flooring to keep fibers from entering the air. Repairs are less expensive than removal, and usually the best all-around option. However, if the materials are already quite damaged, and they'll eventually need to be removed, it's better to spring for removal right away. Applying a sealant or covering can make it more difficult to remove the materials later. After repairs have been conducted, it's still important to be careful around the materials that contain asbestos. Be cautious around the materials in question so you don't end up disturbing them and releasing the asbestos fibers. Take the following measures to live safely with asbestos: Keep activities to a minimum in the areas that have asbestos. For example, if the walls in your basement contain asbestos, don't spend more time than necessary there. Don't saw, sand, scrape, drill, or otherwise damage materials that contain asbestos, even after sealant has been applied. Don't use abrasive cleaning materials on materials that have asbestos. Don't vacuum or sweep debris on the floor that might contain asbestos. If further damage occurs, have it repaired by a professional. If you'd simply prefer not to have asbestos-containing materials in the building, you can opt for removal instead of repair. Hire a contractor who has been trained by the EPA. The removal process is more dangerous than the repair process, and if done improperly it can pose a serious health risk to individuals using the building.

Problem: Write an article based on this summary: Go on day hikes first, then overnight hikes. Pick a general destination for your backpacking trip. Pick a specific park or wilderness area. Plan your route through the area. Be fairly conservative with your routes and schedule on your first trips. Check to see if your destination requires permits or other advance preparation. Find out local fire regulations.

Answer:
Before you set out for a multi-day trip, try a couple of day hikes through various kinds of terrain and weather to find out how it suits you. It's good idea to make sure you enjoy hoofing around out in the woods before you find yourself out in the middle of a 14 mile loop in the wilderness. Try a few hikes without any gear, but plenty of water, light snacks, a map of the area, and the right boots. Go out for a mile or two with some friends and have fun. If you like that, try going on a longer hike, for several miles of somewhat rougher terrain. If you like that, take your bag with you and see how you enjoy it. Gradually build up to a series trip. Are you interested in the mountains? The grasslands? The great lakes? Depending on where you live, the backcountry may be close by, or you may want to venture out farther for a serious hiking experience. In most areas, you shouldn't need to travel more than a half a day by car to find a good National or State Park in which you can hike and camp. Pick an appropriate time of year for that destination, as well. Some destinations are very crowded at certain times of year, or around holidays, while others are inappropriate for backpacking at certain times of the year. It'd be bad to head out to the desert in the middle of the summer if you're a first-timer. It's also usually good to avoid areas with bears during bear-heavy seasons, which will vary from region to region. Want to hike the Cumberland Gap? Explore Yosemite? Pitch a tent in the Grand Tetons? Once you've settled on a particular region of the country you'd like to explore, pick an area that's appropriate for backcountry camping. Within the US, here are some of the best destinations for serious camping: Yosemite National Park, CA Joshua Tree, CA Denali National Park, AK White Mountain National Forest, NH Olympic National Park, WA Zion National Park, UT Glacier National Park, MT Big Bend National Park, TX Different wilderness areas and parks will have a variety of options available to backcountry hikers, so consult park maps of the area to find the specific trails, or find some online by checking out the National Parks website. Typically, long hikes come in three styles, which you can pick based on the difficulty, the type of terrain, and the sights that you may want to see at your destination. The three basic types of backcountry hikes include: Loop hikes, which follow a long circle that will allow you to end up back where you started. Out and back hikes, during which you'll hike to a specific destination and then retrace your steps backward. End to end hikes usually require leaving a car at both ends, or arranging pick-up at your eventual destination. This is only typically done for very long hikes that go through multiple areas. While you might want to jump right in and do something difficult, you'll need to consider the terrain, weather, and the experience and conditioning of your group when planning how many miles you will travel each day. Most trails are rated for difficulty, so you'll usually want to stick with anything at a level 1 or 2 for your first several hikes. They'll be challenging enough. Novices and weekend warriors should plan on hiking no more than 612 miles (9.719.3km) per day of a given hike. In relatively tough terrain, that'll be more than enough. Experienced hikers in good shape can sometimes do 1025 miles (1640km) per day, depending on terrain, but it's usually best to not push it. If you're camping on public land, there will typically be a small fee associated with coming into the park itself, and another fee associated with camping. They're usually pretty small, and you can get away with no more than $15 dollars or so a night, depending on the season. At most parks, you'll have to display a permit on your car while you hike, and something on your tent, or bag, as well. The local regulations will be explained to you when you check in to the ranger's office upon your arrival. Most National Parks and other public lands will also have guidelines specific to their environments, at the time of year you're camping. For example, Yosemite National Park requires the use of bear-proof canisters for food. Campfires are great, so long as they're legal. Many areas prohibit fires during dry periods. At other times, they may only be allowed in specific locations, typically fire rings located at campsites. In some places a separate campfire permit is required to use a backcountry cooking stove. Never, ever, leave a fire unattended. Do not light a fire unless you have enough water available to extinguish it thoroughly. As a precaution, clear a 15-foot (~5m) circular area around your fire, to prevent the wind from igniting any materials outside of your fire pit.
