PHP function does not return alphanumeric string
I constructed a php function given below to return a string for eg. 007ABX, but function does not return that string..

function abc($aa) { //some code goes here $aa = '007ABX'; return $aa; }

$ab = abc($aa); echo $ab //$ab does not print anything here.
