I have a development version of PHP on Apache. I moved it to production and got this weird notices in my website. I don't have it on development version. How to enable these notices on my development version of website to fix them?
If you have access to your php.ini, then Björn answer is the way to go.
However, if you don't, or if you want to change a particular script / project error level, do this at the beginning of your code:
ini_set('display_errors', 1);
// Enable error reporting for NOTICES
error_reporting(E_NOTICE);
You can see which levels are available for error_reporting here: http://us2.php.net/manual/en/function.error-reporting.php.
It's always a good practice not to show any errors on production environments, but logging any weird behaviors and sending by mail to the administrator. NOTICES should only be enabled on development environments.
Change your php.ini file, the line that says error_reporting, to E_ALL.
I.e:
error_reporting = E_ALL
Seb is right, though you really should use constant for error_reporting().
error_reporting(E_NOTICE);
You can use bitwise operations to pick exactly the messages you want to display. For example:
// notices and warnings
error_reporting(E_NOTICE | E_WARNING);
// everything except errors
error_reporting(E_ALL ^ E_ERROR);

I have a script that need Strict Standards Off ~E_STRICT, but I cant understand how can I off strict standards on PHP. I have centos 6.4 with WHM installed VPS
If you want to repport all errors but stric, use error_reporting(E_ALL ^ E_STRICT);. If you want to repport all errors, use error_reporting(E_ALL); if you want to log all errors but not show them, use ini_set('display_errors', '0'); error_reporting(E_ALL); or change the display_errors directive in the php.ini manually and set it to off.
Every time I have an error within my code and try to run it, the page becomes inaccessible. This is clearly very frustrating as it's hard debugging code with no feedback.
Relevant information from cPanel:
Apache version 2.2.22
PHP version 5.3.14
MySQL version 5.1.68-cll
Architecture x86_64
Operating system linux
If more information is required then please ask, I'm sorry I cannot provide any more information but frankly I am stumped.
Thanks.
Enable error reporting to see what error PHP had, if it had one.
There are several places you can look, firstly try checking your Apache error log. In many cases this is located in /var/log/apache2/error.log . Another way to debug a page like this is to enable error logging.
The simplest way of doing this being adding these lines to your php file:
ini_set('display_errors',1);
error_reporting(E_ALL);
In addition to this, you can also clean up the errors formatting by adding:
ini_set('html_errors', 'On');
In addition to this method of enabling error reporting, you may also enable them from you configuration file by adding the following line:
error_reporting = E_ALL
You need to update your php.ini to display errors. There are a couple settings.
Search your php.ini for display_errors and error_reporting. The file is usually commented very well on the options for error reporting, but error_reporting = E_ALL is a typical setting. Sometimes people want to suppress notices and set error_reporting to E_ALL & ~E_NOTICE.
display_errors = On is the config to print the errors to the screen.
After changing your php.ini, Apache usually needs to be restarted. I'm not sure how much control you have over your server, so if you can't restart Apache but you have a php.ini available, your host probably has it configured so you don't need to restart.
I'm trying to get the warnings to show in my php error log.
My ISP has some warnings showing and I need to be able to see them on my test server.
error_reporting = E_ALL & ~E_NOTICE
display_errors = off
display_startup_errors = Off
log_errors = On
error_log = "C:\php-errors.txt"
I've upgraded my php version too 5.2.17
I also have
register_globals = Off
Like my ISP, but I can't get any warnings to show.
ini_set('display_errors', 'on'); is a great way to change php configurations settings specific for that page only. Include it in a global header/initialization file to make it application specific. Also, as mentioned before error_reporting(E_ALL); is good for this too.
Code at the top your scripts:
ini_set('display_errors', 'on');
error_reporting(E_ALL);
Be sure to use these only for development environments only.
Set display_errors to On to display the warnings in the page (instead of in the logfile) and set error_reporting to E_ALL | E_STRICT to display all warnings and errors in your php.ini.
If you want to show all possible warnings, try error_reporting(-1);, or you can put error_reporting = -1 into the php.ini file on your test server. It works, because the internal variable is used as a bit-field, and -1 sets all the bits on, hence, showing all possible errors.
To make sure that the error_reporting is still set to what you think, the variable returns the currently set level.
$prevErrLevel = error_reporting(-1);
echo "errlevel was: $prevErrLevel before setting to all.", __FILE__,':',__LINE__;
I need to setup my PHP script at the top to disable error reporting for strict standards.
Can anybody help ?
Do you want to disable error reporting, or just prevent the user from seeing it? It’s usually a good idea to log errors, even on a production site.
# in your PHP code:
ini_set('display_errors', '0'); # don't show any errors...
error_reporting(E_ALL | E_STRICT); # ...but do log them
They will be logged to your standard system log, or use the error_log directive to specify exactly where you want errors to go.
For no errors.
error_reporting(0);
or for just not strict
error_reporting(E_ALL ^ E_STRICT);
and if you ever want to display all errors again, use
error_reporting(-1);
All above solutions are correct. But, when we are talking about a normal PHP application, they have to included in every page, that it requires. A way to solve this, is through .htaccess at root folder.
Just to hide the errors. [Put one of the followling lines in the file]
php_flag display_errors off
Or
php_value display_errors 0
Next, to set the error reporting
php_value error_reporting 30719
If you are wondering how the value 30719 came, E_ALL (32767), E_STRICT (2048) are actually constant that hold numeric value and (32767 - 2048 = 30719)
The default value of error_reporting flag is E_ALL & ~E_NOTICE if not set in php.ini.
But in some installation (particularly installations targeting development environments) has E_ALL | E_STRICT set as value of this flag (this is the recommended value during development). In some cases, specially when you'll want to run some open source projects, that was developed prior to PHP 5.3 era and not yet updated with best practices defined by PHP 5.3, in your development environment, you'll probably run into getting some messages like you are getting. The best way to cope up on this situation, is to set only E_ALL as the value of error_reporting flag, either in php.ini or in code (probably in a front-controller like index.php in web-root as follows:
if(defined('E_STRICT')){
error_reporting(E_ALL);
}
In php.ini set :
error_reporting = E_ALL & ~E_NOTICE & ~E_STRICT
WordPress
If you work in the wordpress environment, Wordpress sets the error level in file wp-includes/load.php in function wp_debug_mode(). So you have to change the level AFTER this function has been called ( in a file not checked into git so that's development only ), or either modify directly the error_reporting() call
I didn't see an answer that's clean and suitable for production-ready software, so here it goes:
/*
* Get current error_reporting value,
* so that we don't lose preferences set in php.ini and .htaccess
* and accidently reenable message types disabled in those.
*
* If you want to disable e.g. E_STRICT on a global level,
* use php.ini (or .htaccess for folder-level)
*/
$old_error_reporting = error_reporting();
/*
* Disable E_STRICT on top of current error_reporting.
*
* Note: do NOT use ^ for disabling error message types,
* as ^ will re-ENABLE the message type if it happens to be disabled already!
*/
error_reporting($old_error_reporting & ~E_STRICT);
// code that should not emit E_STRICT messages goes here
/*
* Optional, depending on if/what code comes after.
* Restore old settings.
*/
error_reporting($old_error_reporting);
