How to catch this error: "Notice: Undefined offset: 0"

Question

I want to catch this error:

$a[1] = 'jfksjfks'; try {       $b = $a[0]; } catch (\Exception $e) {       echo "jsdlkjflsjfkjl"; } 

Edit: in fact, I got this error on the following line: $parse = $xml->children[0]->children[0]->toArray();

You need to define your custom error handler like:

<?php  set_error_handler('exceptions_error_handler');  function exceptions_error_handler($severity, $message, $filename, $lineno) {   if (error_reporting() == 0) {     return;   }   if (error_reporting() & $severity) {     throw new ErrorException($message, 0, $severity, $filename, $lineno);   } }  $a[1] = 'jfksjfks'; try {       $b = $a[0]; } catch (Exception $e) {       echo "jsdlkjflsjfkjl"; }
