More organized.

About the changes in 
```php
$strText = "i'm a lasagna hog";

$strTmp = str_split($strText);
$strTmp = array_reverse($strTmp);
$strTmp = join("",$strTmp);

echo $strTmp;
```
to
```php
echo join("", array_reverse(str_split("i'm a lasagna hog")));
```
I've made this change just to make the code more similar the original in javascript
```javascript
"i'm a lasagna hog".split("").reverse().join("");
```
