I am running a php page form the command line to update a mysql db once a php exec command has completed. This has been working OK.
However, I have just reinstalled my server and now the script is returning the following error when I run it on the command line:
Fatal error: Call to undefined function mysql_connect()
The script runs fine in the browser which means mysql is installed OK. How do I enable mysql in PHP to be run from the command line?
First of all, you can use
from the command-line, to check which extensions are enabled.
If mysql is not in the list, it means it’s not enabled / loaded — which is probably the case, here.
Then, you’ll want to use
to check which
.ini file(s) is/are read by PHP.
Once you’ve found out which
php.ini file is used, you’ll have to edit it, and add something like this :
; configuration for php MySQL module extension=mysql.so
To load the
Depending on your distribution, the might be a
.ini file per extension (Ubuntu does that, for instance).
If that’s the case, you could also create a new
.ini file (
mysql.ini for instance) next to the other ones, and put the two lines I posted into that new file.
Check the path to your PHP executable. You didn’t mention which OS this is under, but, for example, under OSX just running
php executes the built-in PHP interpreter. If you’re using MAMP you’ll need to run
/Applications/MAMP/bin/php5.2/bin/php (or whatever your path is) to imitate what’s running in your browser.
Alter the path to your web server’s php accordingly (based on AMP installation, OS, etc.).
I had a similar problem a short time ago (maybe it’s the same problem for you):
I had specified my prefered php.ini in Apache’s config. However, this obviously doesn’t affect php in CLI. Check which
php.ini is used by php:
php --ini. Either modify it or choose a different config file by changing some of these:
php.ini is searched in these locations (in order):
SAPI module specific location (PHPIniDir directive in Apache 2, -c command line option in CGI and CLI, php_ini parameter in NSAPI, PHP_INI_PATH environment variable in THTTPD)
The PHPRC environment variable. Before PHP 5.2.0 this was checked after the registry key mentioned below.
As of PHP 5.2.0, the location of the php.ini file can be set for different versions of PHP. The following registry keys are examined in order: [HKEY_LOCAL_MACHINE\SOFTWARE\PHP\x.y.z], [HKEY_LOCAL_MACHINE\SOFTWARE\PHP\x.y] and [HKEY_LOCAL_MACHINE\SOFTWARE\PHP\x], where x, y and z mean the PHP major, minor and release versions. If there is a value for IniFilePath in these keys, then the first one found will be used as the location of the php.ini (Windows only).
- [HKEY_LOCAL_MACHINE\SOFTWARE\PHP], value of IniFilePath (Windows only).
Current working directory (except CLI)
The web server’s directory (for SAPI modules), or directory of PHP (otherwise in Windows)
Windows directory (C:\windows or C:\winnt) (for Windows), or –with-config-file-path compile time option
I’ve just modified the PHPRC environment variable to my prefered location of
For me the answer was to change the first line in my script from ‘#!/usr/bin/php’ to ‘#!/usr/bin/php -c /etc/php.ini’.
Even though ‘php –ini’ indicated it was processing the correct .ini file, it wasn’t, so I had to force it on the header line of the script.
