Here is a cool trick you might not know if you want to return multiple values from a function and assign them to variables with different names each.
Here Is How It Works:
Say you have the following function returning an array.
function SomeFunction() { /** lots of code **/ return array($value1, $value2, $value3); }
Now to assign each value to a different variable, in the order in which you returned them, do the following.
list($variable1,$variable2,$variable3)=SomeFunction();
Returning an Array of Associative Keys
You could just assign SomeFunction() to a variable, which would make it an array, but you would then have to access each value using numeric keys e.g $var[0] would hold $value1. A better approach if you want to do this would be to make associative keys in the returning array:
function SomeFunction() { /** lots of code **/ return array('key1'=>$value1, 'key2'=>$value2, 'key3'=>$value3); }
Usage:
$someArray=SomeFunction(); echo $someArray['key1']; // shows $value1
