Enabling PostgreSQL support in PHP on Mac OS X
I'm having a terribly difficult time getting the command "pg_connect()" to work properly on my Mac. I'm currently writing a PHP script (to be executed from console) to read a PostgreSQL database and email a report.
I've gone into my php.ini file and added
extension=pgsql.so
But, I'm met with the following error.
PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/extensions/no-debug-non-zts-20090626/php_pgsql.so' - dlopen(/usr/lib/php/extensions/no-debug-non-zts-20090626/php_pgsql.so, 9): image not found in Unknown on line 0
PHP Fatal error: Call to undefined function pg_connect() in... (blah file here)
When running phpinfo(), I see nothing about PostgreSQL, so what is my issue here?
The PHP version that comes bundled with OS X doesn't include PostgreSQL. You'll have to compile the extension yourself. Here are some instructions:
- Find your version of PHP:
php -v. - Download the version of PHP that matches yours:
curl -O http://us.php.net/distributions/php-5.3.3.tar.gz. (This example downloads PHP 5.3.3 but this must match your version) - Extract the archive you downloaded:
tar -xzvf php-5.3.3.tar.gz - Change to the PostgreSQL's extension directory:
cd php-5.3.3/ext/pgsql/ - Type
phpize. - Type
./configure. - Type
make. - Type
sudo make install. - Add the extension to you
php.inifile by addingextension=pgsql.so. (You may already have done this) - Restart Apache.
Update for OS X Mountain Lion
Apple has removed autoconf from the newer versions of XCode so the procedure above will fail at #5. To solve that problem:
- Type
/usr/bin/ruby -e "$(/usr/bin/curl -fksSL https://raw.github.com/mxcl/homebrew/master/Library/Contributions/install_homebrew.rb)". - Type
sudo chown -R $USER /usr/local/Cellar. - Type
brew update. - Type
brew install autoconf.
That should install autoconf and allow you to install the module using the instructions above.
If you use home brew, you can solve this with a command as simple as:
brew install php55-pdo-pgsql
for other php version, search with:
brew search pgsql
