Error to Exception error_handler for PHP

exception_error_handler.php

<?php
function exception_error_handler($severity, $message, $file, $line) {
    if (!(error_reporting() & $severity)) {
        // This error code is not included in error_reporting
        return;
    }
    throw new ErrorException($message, 0, $severity, $file, $line);
}
set_error_handler("exception_error_handler");

Example of use (after including/inserted at top the code):

<?php
/* Trigger exception */
strpos();
?>

Another use is to catch file_get_content errors (uncatchable) by converting them to exceptions (catchable)
