The file name where the PHP detection function is located

A very simple function, using the reflection mechanism in PHP, specifically using the ReflectionFunction class, to obtain the specific location in the PHP script where the specified function is located. Create a reference script.

Php code

// Filename: functions.php   
<?php  
function now() {  
    return time();  
}  
?>

calls the function.

Php code

// Filename: call_now.php  
<?php  
require &#39;functions.php&#39;;  
   
Reflection::export(new ReflectionFunction(&#39;now&#39;));  
// Function [ function now ] { @@ H:\www\functions.php 2 - 4 }  
?>
