Okay heres something that can come inhandy of be totally useless to you depending on how you do things. I, myslef have used this before. Variable variables are a variable where the variables name is a variable ex.
PHP Code:
<?php
$name = "test";
$test = "hello world";
echo $$name;
?>
The above would print out hello world.
It prints out hello world instead of test because your using a variable variable. Lets look at this an easier way. The last line,
can look confusing but if we add {} it looks a little cleaner.
If people still dont understand variable variables if you were to break down the last line step by step, it would be:
PHP Code:
1. echo ${$name};
2. echo ${test};
3. echo $test;
