Menunjukkan semua kesalahan dan peringatan

UPDATE 2:

Saya sekarang telah dihapus berikut ini dari .file php:

<?php error_reporting( E_ALL ); ?>

Saya telah menetapkan display_erros di php.ini sebagai berikut:

display_errors = On

Kesalahan pelaporan ditetapkan sebagai berikut di php.ini:

error_reporting = E_ALL | E_STRICT

Setelah restart Apache, aku masih tidak mendapatkan kesalahan/peringatan.

UPDATE 1:

Saya telah berubah error_reporting di php.ini dari:

error_reporting = E_ALL & ~E_DEPRECATED

untuk

error_reporting = E_ALL | E_STRICT

Setelah itu saya restart Apache, misalnya

/etc/init.d/apache2 restart

Tetapi halaman yang akan masih tidak menampilkan kesalahan/peringatan apapun.

PERTANYAAN AWAL:

Skrip berikut ini adalah menghasilkan sebuah peringatan karena $err berada di dalam pernyataan if. Mengapa peringatan ini tidak ditampilkan pada halaman PHP di web browser?

Aku harus melihat Apache log untuk melihat peringatan. Juga, jika aku sengaja mengubah "masukkan ke" untuk "hapus ke", tidak menampilkan pesan kesalahan pada halaman PHP. Mengapa kesalahan-kesalahan yang tidak ditampilkan pada halaman PHP?

Menampilkan kesalahan bisa dimatikan di php.ini atau file konfigurasi Apache.

Anda dapat mengubahnya di dalam script:

error_reporting(E_ALL);
ini_set('display_errors', 1);

Anda akan melihat pesan yang sama di PHP error log.

Langsung dari php.ini file:

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
; Error handling and logging ;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

; This directive informs PHP of which errors, warnings and notices you would like
; it to take action for. The recommended way of setting values for this
; directive is through the use of the error level constants and bitwise
; operators. The error level constants are below here for convenience as well as
; some common settings and their meanings.
; By default, PHP is set to take action on all errors, notices and warnings EXCEPT
; those related to E_NOTICE and E_STRICT, which together cover best practices and
; recommended coding standards in PHP. For performance reasons, this is the
; recommend error reporting setting. Your production server shouldn't be wasting
; resources complaining about best practices and coding standards. That's what
; development servers and development settings are for.
; Note: The php.ini-development file has this setting as E_ALL. This
; means it pretty much reports everything which is exactly what you want during
; development and early testing.
;
; Error Level Constants:
; E_ALL             - All errors and warnings (includes E_STRICT as of PHP 5.4.0)
; E_ERROR           - fatal run-time errors
; E_RECOVERABLE_ERROR  - almost fatal run-time errors
; E_WARNING         - run-time warnings (non-fatal errors)
; E_PARSE           - compile-time parse errors
; E_NOTICE          - run-time notices (these are warnings which often result
;                     from a bug in your code, but it's possible that it was
;                     intentional (e.g., using an uninitialized variable and
;                     relying on the fact it is automatically initialized to an
;                     empty string)
; E_STRICT          - run-time notices, enable to have PHP suggest changes
;                     to your code which will ensure the best interoperability
;                     and forward compatibility of your code
; E_CORE_ERROR      - fatal errors that occur during PHP's initial startup
; E_CORE_WARNING    - warnings (non-fatal errors) that occur during PHP's
;                     initial startup
; E_COMPILE_ERROR   - fatal compile-time errors
; E_COMPILE_WARNING - compile-time warnings (non-fatal errors)
; E_USER_ERROR      - user-generated error message
; E_USER_WARNING    - user-generated warning message
; E_USER_NOTICE     - user-generated notice message
; E_DEPRECATED      - warn about code that will not work in future versions
;                     of PHP
; E_USER_DEPRECATED - user-generated deprecation warnings
;
; Common Values:
;   E_ALL (Show all errors, warnings and notices including coding standards.)
;   E_ALL & ~E_NOTICE  (Show all errors, except for notices)
;   E_ALL & ~E_NOTICE & ~E_STRICT  (Show all errors, except for notices and coding standards warnings.)
;   E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR  (Show only errors)
; Default Value: E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED
; Development Value: E_ALL
; Production Value: E_ALL & ~E_DEPRECATED & ~E_STRICT
; http://php.net/error-reporting
error_reporting = E_ALL & ~E_DEPRECATED & ~E_STRICT

Murni untuk pengembangan aku pergi untuk:

error_reporting = E_ALL ^ E_NOTICE ^ E_WARNING

Juga don't lupa untuk menempatkan display_errors untuk di

display_errors = On

Setelah itu, restart server Apache pada Ubuntu:

sudo /etc/init.d/apache2 restart

Aku bisa mendapatkan semua kesalahan melalui kode di bawah ini:

ini_set('display_startup_errors', 1);
ini_set('display_errors', 1);
error_reporting(-1);

Kesalahan PHP dapat ditampilkan oleh salah satu dari metode di bawah ini:

ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);

Untuk lebih jelasnya:

Set ini pada php.ini:

;display_startup_errors = On
display_startup_errors=off
display_errors =on
html_errors= on

Dari halaman PHP anda, gunakan filter yang cocok untuk pelaporan kesalahan.

error_reporting(E_ALL);

Pelapor dapat dibuat sesuai dengan kebutuhan.

E_ALL
E_ALL | E_STRICT

Anda dapat melihat penjelasan rinci di sini.

ini_set('display_errors', 1);

// 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 (see changelog)
error_reporting(E_ALL);

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

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

Changelog

  • 5.4.0 E_STRICT menjadi bagian dari E_ALL

  • 5.3.0 E_DEPRECATED dan E_USER_DEPRECATED diperkenalkan.

  • 5.2.0 E_RECOVERABLE_ERROR diperkenalkan.

  • 5.0.0 E_STRICT diperkenalkan (bukan bagian dari E_ALL).
