This line of code is making a call to "my_function." In this case we will give my_function an input of 8, and PHP will echo the returned output value. Test the script, you will get a value of 60. The magic of coding with functions is the ability to reuse and recycle the same code over and over. We are now calling my_function two more times and reusing its code. Also notice how the in the code above the call to my_function is treated like a number. Always treat calls to functions as the datatype you expect to get back (whether it is a number, string, boolean, or resource). Test the script, you will get a value of 60 followed by a value of 260.

DVD players need a power source in order to work, so double-check that the player is plugged into the wall or a power strip. DVD players will display on one of the Input or Auxiliary channels. They will not show up on Channel 3 or 4 like some VCRs. Some TVs will label the Input channels based on the type of input, such as "HDMI", "AV", and "COMPONENT." Refer back to Method one if you have a question about which input type you are using. Sometimes, old cables can become frayed and the plugs can start coming loose. This can lead to a poor or nonworking connection. Try a new cable to see if your problem can be fixed. Note: There are a lot of companies that market extremely expensive cables. For the most part, you will not see any significant difference using high-end cables. This is especially true for HDMI, where a $5 cable will perform the same as an $80 cable.

Almost all versions of Windows in North America and Western Europe support Alt codes. These are key combinations that can be used in any text field to access special characters, such as the en and em dash. If you are using a laptop, you will need to press the NumLock key first in order to activate the numeric pad. Pressing the number keys on the top of the keyboard will not result in symbols appearing. Hold down the Alt key, press 0150 on the numeric pad, and then release the Alt key. The en dash will appear in the text field where your cursor is. Hold down the Alt key, press 0151 on the numeric pad, and then release the Alt key. The em dash will appear in the text field where your cursor is.

Items to remember include: deodorant, toothbrush/toothpaste, shampoo/conditioner, body wash, face lotion, face wash, hairbrush, styling products, contact lens case/solution, hand sanitizer, razor/shaving cream, feminine hygiene products, and lip balm. Try to get as many items as you can in travel-sized containers. Local drugstores offer mini versions of commonly used toiletries, or you can buy your own travel-sized containers and fill them yourself. For a 5 day vacation, you will want to bring 2-3 pairs of shorts or pants, 3-4 tops, a light jacket (or a heavy jacket, depending on where you are traveling), and 1 formal outfit if you are planning on attending a nice restaurant or event. If you are going to the beach, pack 2-3 swimsuits/trunks. Try to coordinate all clothing items so they can be worn with each other in any combination. Bring 1-2 sleep outfits for the week. If you tend to get cold at night, you may also want to bring a light sweater to put on in the evenings. If you are trying to save space, you could plan on wearing the same shirt you wear during the day to bed at night. Bring 1 pair of comfortable shoes for walking. If you are planning on going out, bring 1 pair of dress shoes or flats that go with your outfit. For the beach, bring 1 pair of sandals. The fewer pairs of shoes you bring, the lighter your bag will be. Don't forget to pack shoes for any special activities you will be doing, like mountain climbing or white water rafting. Wear your bulkiest pair of shoes when you are traveling to your destination to save room in your luggage. Bring 4-5 pairs of underwear, 4-5 pairs of socks, 2-3 undershirts/bras, and any slips or specialty items you might need (for example, if you need a backless bra for a dress). If you have limited packing space, bring fewer pairs of undergarments and plan on washing dirty clothes in the sink where you are staying. Some accommodations offer washing and drying machines that you can use while you are traveling. Some things you may like to have with you are sunglasses, scarves, hats, jewelry, ties, and belts. If packing jewelry, be careful to not bring anything extremely valuable in case it gets lost or stolen. It can also be fun to buy new accessories as souvenirs when you travel, like scarves or hats. If you think you may like to do this, leave those items at home to save space. Items to remember: cell phone charger, voltage adapter, video/MP3 player, earphones, camera, electronic reader. For a 5 day trip, you might not need all of these items, so think carefully about what you are planning to do on your trip and what you'll need to take with you. This will help ensure you don't run out of anything while you are away! If you take birth control pills, remember to bring those along with you, too. Bring a list of medications with you to keep on hand in case there is an emergency on your trip.
