How to log PHP compiler errors?

Question

How can I determine why a PHP page on my web-host has not compiled?

Where are the compiler errors logged to?

On my shared host, they're in a log file in the same directory as the PHP. — Anirudh Ramanathan

Should be in the same directory as the file that runs the code. Switch all error reporting on with:

error_reporting(E_ALL);
ini_set('error_reporting', E_ALL);

ini_set('error_log', 'script_errors.log')  // change here
ini_set('log_errors', 'On')

Is there a way to have all these errors written to a file of my choice?

I think, but dont hold me to it, something like this: ini_set(‘error_log’, ‘script_errors.log’) ini_set(‘log_errors’, ‘On’)

Try This:

Put the following code on the top of your file:

ini_set("log_errors", 1);
ini_set("error_log", "/path/to/php-error.log");

You can find it in cPanel of your host.

but some hosts combined all errors from all sites on the same server in one log file.

you have to search for your own errors.

There's no such thing as compiler errors in PHP. Every error that occurs is sent directly to the browser in form of HTML data. Check that you have set error_reporting(E_ALL); and display_errors(1); in your script.

Whenever my PHP pages have some kind of syntax error they return The remote server returned an error: (500) Internal Server Error.

That's likely because you dont have error reporting on and it outputs 500 error as there is no error handler, with error reporting on, it will be 400, but list the details of the errors.

Maybe there wasn't, but there is now. CompileError is thrown for some compilation errors, which formerly issued a fatal error.

PHP not normally being compiled, I guess you are looking for runtime errors. How to display runtime errors can be controlled with the error_reporting() method.

That said, there are indeed PHP-compilers like HipHop by Facebook, so if "compiler errors" are what you are looking for, I believe you will have to elaborate a bit further on your question.
