Super simple example to output where your function was called from (file, function, line number):
<?php
// Prints the file name, function name, and
// line number which called your function
// (not this function, then one that called
// it to begin with)
function debugPrintCallingFunction () {
$file = 'n/a';
$func = 'n/a';
$line = 'n/a';
$debugTrace = debug_backtrace();
if (isset($debugTrace[1])) {
$file = $debugTrace[1]['file'] ? $debugTrace[1]['file'] : 'n/a';
$line = $debugTrace[1]['line'] ? $debugTrace[1]['line'] : 'n/a';
}
if (isset($debugTrace[2])) $func = $debugTrace[2]['function'] ?
$debugTrace[2]['function'] : 'n/a';
echo "<pre>\n$file, $func, $line\n</pre>";
}
?>
