Command line php mysqli fails but works via web se

I have a shell script that calls a php script to insert records in database after parsing text file. When it calls the PHP script I get errors that it cannot find mysqli:

PHP Fatal error:  Class 'mysqli' not found in /path/to/php/file.php on line 5

This failed in local on Macbook Pro with Nginx and PHP-FPM and Mysql 5.5.x and after I added the socket param to mysqli call, it worked in local. This worked with local db!

$mysqli = new mysqli("localhost", "user", "pass", "mydb", 3306, "/tmp/mysql.sock");

I deployed to Linux server (CentOS6 that has 'yum install php' with PHP 5.3.x) installed. I changed the connection to a remote db server so dropped the "/tmp/mysql.sock" because db not running on this server.

Shell script calling php to execute script:

php -c "/etc/php.ini" -f "/path/to/php/file.php"

Given I am not running mysql locally, how do I get it to recognize the mysqli lib and execute. It's on CentOS6. I even tried adding mysqli.so to php.ini file and got following error:

[mike@app2 myapp]# php -version
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/mysqli.so' - /usr/lib64/php/modules/mysqli.so: cannot open shared object file: No such file or directory in Unknown on line 0
PHP 5.3.3 (cli) (built: Feb  2 2012 23:47:49)

Thanks for any help resolving this. Normally I'd use mysql(query) but need mysqli() for some prepared statements and other bits in the script.

回答1:

I found that mysqli was not installed with PHP and ran the following command:

>php -i

This returned the phpinfo() and found no mention of mysqli. I then ran the 'yum' command to install php-mysqli:

>yum install php-mysqli

After this the script worked successfully. Hope this helps others that might run into similar.

PHP CLI will have its own environmental setup from that used by the webserver. If you don't have mysqli available in the CLI environment that would cause this issue.
