Catch warnings

[Chris92]

Is there any way to catch warnings without defining a warning handler?

Example:

try
{
$settings = parse_ini_file( 'main.ini' );
}
catch( ErrorException $e )
{
throw new ErrorException('No main configuration file found for webiste', '0003');
}

 

Only ends up throwing a warning if the file doesn't exist. I want to catch it and throw an error.

<?php

try {
// Suppress usual errors the function would echo using @
if( ($settings = @parse_ini_file( 'main.ini' )) === FALSE )
	throw new ErrorException('No main configuration file found for webiste', '0003');
else {
	// everything's okay
}
}
catch( ErrorException $e )
{
echo 'Error found: '.$e->getMessage().' ('.$e->getCode().')';
}

?>

 

Hope that helps.

Well then I might as well just right it out in an if rather than a try statement and not bother catch it.

 

Can you only catch ErrorExceptions in PHP?

In that case, why not write a custom error handler that throws exceptions?

A lot of languages have try..catch blocks, but the implementation can vary. With JavaScript for example, think of them more like PHP errors. You can't "throw" an exception in JS, but you can catch errors JS throws itself -- excluding syntax type errors of course. With PL/SQL (Oracle) there are set exceptions that you can catch within routines that are handed back to the application, for example "NO_DATA_FOUND" - ORA-01403, or you can define your own, but it's a very different definition/handling process than PHP.

 

In your case there is no point in wrapping it within a try..catch block, unless you want to escalate the exception up to a parent catch block. If parse_ini_file threw exceptions on error, then it would also make sense to use one.
