Php try catch not working

4 You can't handle Warnings/Errors with try-catch blocks, because they aren't exceptions. If you want to handle warnings/errors, you have to register your own error handler with
But it's better to fix this issue, because you could prevent it.

4 Exception is only subclass of Throwable. To catch error you can try to do one of the following:
OR more inclusive solution
BTW : Java has similar behaviour. answered Jan 11, 2018 at 7:49

datasagedatasage 18.9k2 gold badges47 silver badges53 bronze badges Welp, unfortunately this is the issue about PHP. Try/catch statements will catch Exceptions, but what you're receiving is an old-school PHP error. You'll have to catch an error like this with: http://php.net/manual/en/function.set-error-handler.php Either that or check to see if $matrix is a mysqli_result object prior to performing mysqli_fetch_array. answered Sep 11, 2012 at 20:55

adhominemadhominem 1,0749 silver badges24 bronze badges This is something that I’ve run into a lot while programming. I’ll create a try catch statement when attempting to access a resource from a third party API and there are 10 different exceptions that need to be caught in order to prevent a 500 error from being thrown. In some cases I want to catch each individual exception but in others I want to catch all Exceptions with one catch method. The following PHP code catches all Exceptions in a try catch
statement. catch (\Throwable $e) will catch all exceptions and allow you to handle the Exception rather than adding multiple catch statements targeted at catching specific Exceptions. Can we use try catch in PHP?The primary method of handling exceptions in PHP is the try-catch. In a nutshell, the try-catch is a code block that can be used to deal with thrown exceptions without interrupting program execution. In other words, you can "try" to execute a block of code, and "catch" any PHP exceptions that are thrown.
Can we use try without catch in PHP?Try, throw and catch
Proper exception code should include: try - A function using an exception should be in a "try" block. If the exception does not trigger, the code will continue as normal.
How can I get 500 error in PHP?Below are common troubleshooting steps that can be taken to resolve a 500 Internal Server Error:. Check the error logs.. Check the . htaccess file.. Check your PHP resources.. Check CGI/Perl scripts.. Can PHP try have multiple catches?PHP allows a series of catch blocks following a try block to handle different exception cases. Various catch blocks may be employed to handle predefined exceptions and errors as well as user defined exceptions.
