Create_function enables the ability to change the scope of functions. You might have a class where
it needs to define a GLOBAL function. This is possible, like:
<?php
class blah {
function blah() {
$z=create_function('$arg1string','return
"function-z-".$arg1string;');
$GLOBALS['z']=$z;
}
}
$blah_object=new blah;
$result=$GLOBALS['z']('Argument 1 String');
echo $result;
?>
Making a function escape it's defined scope can be useful in many situations.
