Debugging my code - How can I find troubled code?

[josel]

Writing some code and testing as I go ... very nice except that when code does not work browser screen is totally blank and I do not get anything that tells me the line where code is broken.

What must I set so that it shows me on screen whatever problem was encountered?

Thanks!

I have changed every setting in my php.conf document and I still do not get any message displayed on screen nor logged to file.

I even added this line of code to my script

error_reporting(E_ALL);

I stopped and restarted my Apache server and nothing still. This kind of makes it hard to troubleshoot if you cannot properly identify the root cause.

Any suggestions?

Thanks,

Jose Lerebours

add this as the first line of your code.

ini_set("display_errors","on");

this may not work if you have parse errors. In which case you must change the equivalent setting in your php.ini file and then restart apache.

recent distros of php came with short_open_tags set to off. if, like me, you are in the habit of writing php code with short tags

<?   ?>

rather than their full form equivalents

<?php ?>

you may find it easier to change this entry in your php.ini file as well.
