Php redirect errors to file

Запись ошибок выполнения PHP скриптов в файл

Все php ошибки нужно обязательно записывать в лог-файл и регулярно изучать его. Если этого не делать — есть шанс пропустить часть багов, которые появляются в процессе работы или тестирования и не выводятся на экран. По умолчанию, запись ошибок в файл отключена на многих конфигурациях (и это правильно!), но есть несколько способов это исправить:

Способ 1 — написать функцию перехвата ошибок и записи их в файл:

# В начале нашего скрипта пишем: set_error_handler('err_handler'); function err_handler($errno, $errmsg, $filename, $linenum) < $date = date('Y-m-d H:i:s (T)'); $f = fopen('errors.txt', 'a'); if (!empty($f)) < $filename =str_replace($_SERVER['DOCUMENT_ROOT'],'',$filename); $err = "$errmsg = $filename = $linenum\r\n"; fwrite($f, $err); fclose($f); >> 

Способ 2 — изменить php.ini:

log_errors = On error_log = /var/log/php_errors.log 

Способ 3 — добавить в .htaccess:

php_value log_errors "On" php_value error_log /var/log/php_errors.log 

Способ 4 — добавить в самое начало php скрипта:

ini_set('log_errors', 'On'); ini_set('error_log', '/var/log/php_errors.log');

Если создание сайтов было выполнено качественно, то и ошибок выводиться на экран не должно. Конечно, не всегда этого можно добиться по этому в идеале, перестраховаться и писать уведомления в файл. Крайне не рекомендуется использовать символ собаки @ для подавления ошибок т.к. в последствии можно пропустить очень важное уведомление.

Php php 5 redirect error to file

Solution 1: You need to first turn off all errors, which can be done using: Then enable error logging and provide path to log file: Put this at the top of your php file. First i changed my Virtualhost config with sudo nano /etc/apache2/sites-available/000-default.conf by adding this at the very top after the VirtualHost *:80 Then created my application .htacess with nano /var/www/html/.htaccess in the root of my application folder with This should give you an idea on how to solve it in Xampp Solution: You cannot catch fatal errors in PHP.

PHP — Redirect Warning/Notice messages to file

You need to first turn off all errors, which can be done using:

Then enable error logging and provide path to log file:

ini_set("log_errors", 1); ini_set("error_log", "/tmp/php-error.log"); 

Put this at the top of your php file.

Your server did not allow to modify your ini settings. So if you want to hide add error and notices you can add error_reporting(0); on config page. // Turn off all error reporting error_reporting(0); Other options are available - // 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 // This is the default value set in php.ini error_reporting(E_ALL & ~E_NOTICE); // For PHP < 5.3 use: 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); 

Error on header information on redirect, That's because you can't use "header()" after the headers are sentthat means for example, when the PHP already send the headers to the

PHP Tutorial (& MySQL) #22 - Checking for Errors & Redirecting

Hey gang, in this PHP tutorial I'll explain how to redirect a user to another page after Duration: 5:01

How to fix redirect error on Php when application run locally

From your question I think you are not able to redirect to a specific page. To redirect in PHP. Try using the following code

header("Location: http://$_SERVER[HTTP_HOST]/taxiapp/admin/dashboard"); 

Let me know if this works for you.

also, make sure your base_url like following

$config['base_url'] = 'http://'.$_SERVER['HTTP_HOST'].':'. $_SERVER['SERVER_PORT'].'/taxiapp/'; 

I faced exactly this same problem but it was on a live server with Ubuntu 16.x This problem is with mod_rewrite and your .htaccess file. So make sure mod_rewrite is properly installed and set up. i did sudo a2enmod rewrite for that and restarted my server.

Now the important part.

First i changed my Virtualhost config with sudo nano /etc/apache2/sites-available/000-default.conf

by adding this at the very top after the VirtualHost *:80

 Options Indexes FollowSymLinks MultiViews AllowOverride All Require all granted 

Then created my application .htacess with nano /var/www/html/.htaccess in the root of my application folder with

 RewriteEngine On RewriteCond % !-f RewriteCond % !-d # Rewrite all other URLs to index.php/URL RewriteRule ^(.*)$ index.php?url=$1 [PT,L] ErrorDocument 404 index.php 

This should give you an idea on how to solve it in Xampp

Php - Redirect to custom error page if there is error in the page, In php you don't redirect when there is an error in the code, you simply catch that error and then you take whatever actions you consider

Redirect to another page when fatal error occurs

You cannot catch fatal errors in php. But there's a workaround that can be useful in your case.

You can register a callback on shutdown using register_shutdown_function .

register_shutdown_function(function() < require_once dirname(__FILE__) . '/file.php'; // use ABSOLUTE path die(); >); 

You may wonder redirecting users to another page using header instead of including file.php and stopping the execution of script. Well, you'll get a warning:

Cannot modify header information - headers already sent by.

Since you cannot send any HTTP header in the shutdown callback.

Redirect error in php with isset and GET variable, You don't need to add isset the code i gave you checks for the GET and the strings mentioned. If they are present you're good if not it

Redirecting STDERR in PHP exec

Update and answer for the benefit of anyone who comes here with a similar issue.

After spending a lot of time on this I gave up with exec() and gave proc_open() a try instead.

Doing it this way now works locally and on the server:

 array("pipe", "r"), // STDIN 1 => array("pipe", "w"), // STDOUT 2 => array("pipe", "w"), // STDERR ); $cwd = getcwd(); $env = null; $proc = proc_open($cmd, $descriptorspec, $pipes, $cwd, $env); if (is_resource($proc)) < // Output test: echo "STDOUT:
"; echo "
".stream_get_contents($pipes[1])."
 
"; echo "STDERR:
"; echo "
 
".stream_get_contents($pipes[2])."
 
"; $return_value = proc_close($proc); echo "Exited with status: "; > ?> 
 
For some reason, missing out the getcwd() part causes the command to fail on the server unless I specify the complete path, whereas locally that is not an issue.
 
With this method I can append 2>&1 to redirect all output to STDIN. To output to a file, the manual shows that the $descriptorspec array can be modified e.g: 2 => array("file", "stderr.log", "a") (I have not yet tested this though)
 
One difference here is that if I want to retrieve the output in PHP, rather than getting all of the lines in an array, I need to read from the streams using stream_get_contents() .
 
I still don't understand why there was an issue with using exec() , but this method seems to work both locally and on the server - If anyone knows why this could be, please let me know!
 
$o = null; $r = null; exec("php test.php 2>&1", $o, $r ); It's quite simple
