I've got an applicaiton with various php scripts. I want to get an idea of how much time it takes for the execution to move from one point to another (there are many such points).
I was looking for a simple php line that I can insert without modification, at different spots in my code and get an output file (NOT generated html) which shows something like:
FILENAME FUNCTION LINENUMBER TIMESTAMP
I've started using this:
file_put_contents('/home/default/public_html/debug.log', __FILE__ . "\t" .
__FUNCTION__ . "\t" . __LINE__ . "\t" . microtime(true)."
", FILE_APPEND);
which is good, but are there better ways of doing the same?
For a simple way to do this, you can either use the global PHP error system with trigger_error() and a E_NOTICE level, or the error_log() function to log in a separate file.
I your case I would recommend the second solution.
With the trigger_error():
<?php
trigger_error("Call will start now", E_NOTICE);
startTheHugeCall();
trigger_error("Call is finished", E_NOTICE);
?>
With the error_log() :
<?php
error_log("Call will start now", 3, "/var/tmp/debugfile.log");
startTheHugeCall();
error_log("Call is finished", 3, "/var/tmp/debugfile.log");
?>

You could use the XDebug extension to generate raw profiling data. It will generate files in your /tmp directory by default that you can crunch using command line tools or various GUIs.
