PHP Warning: Module already loaded in Unknown on line 0

问题

On Mac OSX Mavericks using homebrew php55 whenever I run a a php command I get the following error message (everything runs fine it's just annoying)

PHP Warning:  Module 'intl' already loaded in Unknown on line 0

I ran

php --ini

and the output was

php --ini
PHP Warning:  Module 'intl' already loaded in Unknown on line 0

Warning: Module 'intl' already loaded in Unknown on line 0
Configuration File (php.ini) Path: /usr/local/etc/php/5.5
Loaded Configuration File:         /usr/local/etc/php/5.5/php.ini
Scan for additional .ini files in: /usr/local/etc/php/5.5/conf.d
Additional .ini files parsed:      /usr/local/etc/php/5.5/conf.d/ext-apcu.ini,
/usr/local/etc/php/5.5/conf.d/ext-igbinary.ini,
/usr/local/etc/php/5.5/conf.d/ext-intl.ini,
/usr/local/etc/php/5.5/conf.d/ext-memcached.ini,
/usr/local/etc/php/5.5/conf.d/ext-mongo.ini,
/usr/local/etc/php/5.5/conf.d/ext-uuid.ini,
/usr/local/etc/php/5.5/conf.d/ext-xdebug.ini

Checked in the php.ini file and the only place intl is loaded is at the top and it's commented out. The other files contents look something like:

extension="/usr/local/Cellar/php55/5.5.23/lib/php/extensions/no-debug-non-zts-20121212/intl.so"

where the contents after the last slash is the extension.

I'm not sure where else to look.

Any help is appreciated

I think you have loaded Xdebug probably twice in php.ini.

1. check the php.ini, that you not have xdebug.so for the values extension= and zend_extension=.

2. Check also /etc/php5/apache2 and /etc/php5/cli/. You should not load in each php.ini in this directories the extension xdebug.so. Only one file php.ini should load it.

I had the same issue on mac i.e. Warning: Module 'pdo_pgsql' already loaded in Unknown on line 0. Here's how I solved it.

• Locate the folder conf.d, mine was in the directory /usr/local/etc/php/7.0/conf.d.
• In this folder, there's a file called ext-pdo_pgsql.ini.
• Type sudo nano ext-pdo_pgsql.ini to edit it.
• There should be a line extension="/usr/local/opt/php70-pdo-pgsql/pdo_pgsql.so". Comment it out by adding semi-colon to the beginning of the line i.e. ;extension="/usr/local/opt/php70-pdo-pgsql/pdo_pgsql.so".
• Save the file. (I usually run control + O, control + M).
• Exit the file (control + X).

Hope this helps someone.

To fix this problem, you must edit your php.ini (or extensions.ini) file and comment-out the extensions that are already compiled-in. For example, after editing, your ini file may look like the lines below:

;extension=pcre.so
;extension=spl.so

You should have a /etc/php2/conf.d directory (At least on Ubuntu I do) containing a bunch of .ini files which all get loaded when php runs. These files can contain duplicate settings that conflict with settings in php.ini. In my PHP installation I notice a file conf.d/20-intl.ini with an extension=intl.so setting. I bet that's your conflict.

In my case I had uncoment the ;extension=php_curl.so in php.ini, but Ubuntu was already calling this extension somewhere else.

To find this "somewhere else", on php.ini will informe. On my case: /etc/php/7.1/apache2/conf.d/20-curl.ini was the path.

So now we edit this file (terminal):

sudo nano /etc/php/7.1/apache2/conf.d/20-curl.ini

Comment the ;extension=php_curl.so

Save file and restart apache:

sudo systemctl restart apache2

I had the same issue after upgrading from Fedora Server 24 (PHP 5) to 25 (PHP 7). After investigation, I found that /etc/php.d/ had two different .ini files loading extension=geoip.so.

Previous version of distros had this file named 50-geoip.ini but the recent was changed to 40-geoip.ini, and I suspect that in the version-upgrade process the old hasn't been removed, while the new one has been created.

That was the actual case of the issue. After removing stray 50-geoip.ini from /etc/php.d/ and restarting httpd it just worked flawlessly.

I deleted the 20-mongo.ini file in /etc/php5/cli/conf.d and this solved the problem.

回答8:

There are two "php_intl.dll" files inside php.ini file on 872 and 968 number lines. if php warning module 'intl' already loaded in unknown on line 0 this message is focused on your CLI. Then you should have to remove the semiclone prefixes on line 872. I expect this will done.....

Just for the record as it might help others who are on shared hosting (cPanel).

I had error on shared hosting php7.2: Module 'imagick' already loaded in Unknown on line 0

In the beginning hosting provider said it was my bad configuration (running Yii2.16). But after I showed them, that all Internet related this issue to server configuration -they started to listen to me. After I proved, that there was no error on php7.1 they started to search for the error.

As they told to me - the error was due to configuration in PERL modules or PEAR package, but they did not told me the real issue.

So, if you are on shared hosting - talk to you provider and experiment with PHP versions (if you can change them).

回答10:

Comment out these two lines in php.ini

;extension=imagick.so
;extension="ixed.5.6.lin"

it should fix the issue.

回答11:

I had a similar problem, the problem was that the extension intl was duplicated.

You can check in file C:/xampp/php/php.ini and find "intl". In my case extension=intl is already present and I scrolled again and found a second intl "extension=php_intl.dll".

The extension must one to execution can't execution extension intl again. This will show error like this "Module 'intl' already loaded".

I fixed it by commenting out extension=php_intl.dll using ";" like this ;extension=php_intl.dll. and restarted the apache service.
