Hi thanks, after much RTFM i had to use debug_backtrace();
eventhough it's expensive.
here's how i did it:
// debug(debug_backtrace(),$query);
// $query is optional
define('DEBUG',true);
function debug($trace,$query = null) {
if(DEBUG) {
$caller=array_shift($trace);
error_log("Initiating class: " . $caller['class']);
error_log("Calling function: " . $caller['function']);
error_log("In file: " . $caller['file']);
error_log("@ line: " .$caller['line']);
if(isset($query))
{
error_log("Performing Query: " .$query);
}
error_log("---");
}
else
exit();
}
and at the end of each function i add the following:
function init_userInfo($ai, $v) {
$this->user[$ai] = $v;
debug(debug_backtrace());
}
or if the function has an SQL query:
function insertQuery($query)
{
mysql_query($query)
or die("MySQL Error: " . mysql_error());
debug(debug_backtrace(),$query);
}
the output is generally like this in the php_error.log:
