function causes memory buffer overflow!

[ppowell]

	function dbNameToArrayName($dbName) {
		 if (strlen($dbName) == 0) return $dbName;
		 $dbNameArray = explode('_', $dbName);
		 $a = array();
		 $a[0] =& $this;
		 $a[1] = 'uc_first';
		 if (!array_walk($dbNameArray, $a)) die('error');
		 $dbNameArray[0] = strtolower($dbNameArray[0]);
		 return implode('', $dbNameArray);
	}

The following error occurs on line 1136:

 $a[1]=& $this;

Error:

Fatal error: Allowed memory size of 20971520 bytes exhausted (tried to allocate 58 bytes) in .../applicant.inc on line 1136

Is there a way to alleviate this? We increased the values of memory_limit and max_execution_time in php.ini considerably, to no avail.

Please help!

Thanx

What version of PHP are you using, and with what web server and on what operating system?

[ppowell]

PHP 4.1.2, Linux Red Hat 7.3 and Apache 1.3

Very old stuff. Don't even ask about upgrading 🙁

according to php.net documentation array_walk() has this prototype:

bool array_walk ( array &array, callback funcname [, mixed userdata] )

your code passes an array as the second parameter. why?
