error_reporting

    (PHP 4, PHP 5, PHP 7, PHP 8)

    error_reporting — Sets which PHP errors are reported

    Description

    function error_reporting(?int $error_level = null): int

    The error_reporting() function sets the error_reporting directive at runtime. PHP has many levels of errors, using this function sets that level for the duration (runtime) of your script. If the optional error_level is not set, error_reporting() will just return the current error reporting level.

    Parameters

    error_level

    The new error_reporting level. It takes on either a bitmask, or named constants. Using named constants is strongly encouraged to ensure compatibility for future versions. As error levels are added, the range of integers increases, so older integer-based error levels will not always behave as expected.

    The available error level constants and the actual meanings of these error levels are described in the predefined constants.

    Return Values

    Returns the error_reporting level, before it is changed to error_level.

    Note:

    The error control @-operator changes the error_level during error handling.

    Changelog

    Version Description
    8.0.0 error_level is nullable now.

    Examples

    Example #1 error_reporting() examples

    <?php

// Turn off all error reporting
error_reporting(0);

// Report simple running errors
error_reporting(E_ERROR | E_WARNING | E_PARSE);

// Reporting E_NOTICE can be good too (to report uninitialized
// variables or catch variable name misspellings ...)
error_reporting(E_ERROR | E_WARNING | E_PARSE | E_NOTICE);

// Report all errors except E_NOTICE
error_reporting(E_ALL & ~E_NOTICE);

// Report all PHP errors
error_reporting(E_ALL);

// Report all PHP errors
error_reporting(-1);

// Same as error_reporting(E_ALL);
ini_set('error_reporting', E_ALL);

?>

    Notes

    Tip

    Passing in the value -1 will show every possible error, even when new levels and constants are added in future PHP versions. The behavior is equivalent to passing E_ALL constant.

    If you just see a blank page instead of an error reporting and you have no server access so you can't edit php configuration files like php.ini try this:

- create a new file in which you include the faulty script:

<?php
 error_reporting(E_ALL);
 ini_set("display_errors", 1);
 include("file_with_errors.php");
?>

- execute this file instead of the faulty script file 

now errors of your faulty script should be reported.
this works fine with me. hope it solves your problem as well!
