It maybe using a default PHP configuration. I have found before that it doesn't use the same php.ini or doesn't use one at all. Therefore some of the extensions won't be enabled.

Do this instead:

<pre><code>php -c /etc/php.ini /path/to/script.php
</code></pre>

Where <code>/etc/php.ini</code> is the path to your ini file. You can find this by doing a <code>phpinfo();</code>

blocks|key|2746161|text|虽然这可能是一个基本的答案，但请确保您拥有最新的PHP客户机，并确保它查看的PHP文件夹与您通过Apache工作的文件夹相同。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2746162|如果这不起作用，可以尝试使用mysqli，看看它是否适用于整个PHP的MySQL部分。如果mysqli可以工作，而mysql_connect()不能，那么，这是一个切换到面向对象方面的好时机:-)|2746163|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

While it may be a rudimentary answer, make sure you have the most up to date PHP client, and make sure that it's looking at the same PHP folder that you're working out of through Apache.

If that doesn't work, try playing with mysqli and see if it's globally for the entire MySQL portion of PHP. If mysqli works and mysql_connect() doesn't, well, then, that's as good a time as any to swtich over to the OO side :-)

This problem can arise when you are running Mac OS X and MAMP. The command line version tries to use the MAC OS X version, which happens to load no php.ini by default.

You can check that with the command:

<pre><code>php --ini
</code></pre>

See the missing config file?

<pre><code>Configuration File (php.ini) Path: /etc
Loaded Configuration File: !!! THE CONFIG FILE IS MISSING HERE !!!
Scan for additional .ini files in: /Library/Server/Web/Config/php
Additional .ini files parsed: (none)
</code></pre>

What you have to do is, load up the php.ini of your choice and copy it to the default location of your command line interpreter which is /etc and then run the above command again, you should see that the php.ini file is loaded which should look like:

<pre><code>Configuration File (php.ini) Path: /etc
Loaded Configuration File: /etc/php.ini
Scan for additional .ini files in: /Library/Server/Web/Config/php
Additional .ini files parsed: (none)
</code></pre>

You should also add this to the PHP.ini file in /etc

<pre><code>mysql.default_socket = /Applications/MAMP/tmp/mysql/mysql.sock
</code></pre>

This should fix every problem.

phew..

My system is CentOS.
In my case, the the path to mysql.so is incorrect.

When I type 

<pre><code>php -m
</code></pre>

There is no mysql.

In my original /etc/php.d/mysql.ini
there is only one line:

<pre><code>extension=mysql.so
</code></pre>

So I use command: 

<pre><code>rpm -ql php-mysql | grep mysql.so
</code></pre>

to find out the correct path, which is 

<pre><code>/usr/lib64/php/modules/mysql.so
</code></pre>

then I replaced the line to :

<pre><code>extension=/usr/lib64/php/modules/mysql.so
</code></pre>

then 

<pre><code>service httpd restart 
</code></pre>

and 

<pre><code>php -m
</code></pre>

mysql is now loaded.

I have a script which calls <code>mysql_connect()</code> to connect to a MySQL DB. When I run the script in a browser, it works. However, when I run it from a command line I receive the following error:

<pre><code>Call to undefined function mysql_connect()
</code></pre>

This seems completely paradoxical. Anyone have any ideas as how I can run it from the command line. Btw, I run it from a bash shell like so:

<pre><code>php /path/to/script.php
</code></pre>

PHP: mysql_connect() won't work via command line

我有一个脚本，它调用mysql_connect()来连接到MySQL DB。当我在浏览器中运行该脚本时，它可以正常工作。但是，当我从命令行运行它时，我收到以下错误：Call to undefined function mysql_connect()这似乎完全自相矛盾。对于如何从命令行运行它，任何人都有任何想法。顺便说一句，我从一个bash shell运行它，如下所示：php /path/to/sc
