Addition to tom at r dot je:
It is fine but does not work for method calls like:
<?php
class Car
{
static function getClass()
{
echo get_called_class();
}
}
$method='getClass';
Car::$method(); //prints nothing
?>
So I developed to meet also this issue, and add one extra line not to cause notice errors:
<?php
if(!function_exists('get_called_class')) {
function get_called_class() {
$matches=array();
$bt = debug_backtrace();
$l = 0;
do {
$l++;
if(isset($bt[$l]['class']) AND !empty($bt[$l]['class'])) {
return $bt[$l]['class'];
}
$lines = file($bt[$l]['file']);
$callerLine = $lines[$bt[$l]['line']-1];
preg_match('/([a-zA-Z0-9\_]+)::'.$bt[$l]['function'].'/',
$callerLine,
$matches);
if (!isset($matches[1])) $matches[1]=NULL; //for notices
if ($matches[1] == 'self') {
$line = $bt[$l]['line']-1;
while ($line > 0 && strpos($lines[$line], 'class') === false) {
$line--;
}
preg_match('/class[\s]+(.+?)[\s]+/si', $lines[$line], $matches);
}
}
while ($matches[1] == 'parent' && $matches[1]);
return $matches[1];
}
}
?>
