PHP Warning: Module already loaded in Unknown on line 0

Question

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

Answer 1

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

1. check the php.ini, that not have set 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 these directories the extension xdebug.so. Only one file, php.ini should load it.

   Note: Inside the path is the string /etc/php5. The 5 is the version of PHP. So if you use another version, you always get a different path, like php7.

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
