PHP Add Pcntl multithreaded extensions (Linux)

PHP add pcntl Extension (Linux)

PCNTL extension can support multi-threaded operation of PHP (Linux only)
Originally need to recompile PHP after configrue hint plus--enable-pcntl

Since my PHP is installed with Yum, I can't use the above method
Here's a way to dynamically add extensions to PHP phpize

1. First look at the directory where the Phpize command is located (ps: my directory/usr/bin/phpize)
If not found, perform the installation

Yum Install Php53_devel   (PS: Please note your version)

After the installation is complete. The Phpize command is generated

2, go to php.net download the corresponding version of the PHP source files
Let's take php-5.3.17 as an example, after decompression, into the corresponding module

CD ext/pcntl# first performs phpize/usr/bin/phpize./configure--with-php-config=/usr/bin/php-config   (PS: Please specify the Php-config directory correctly) #编译, install make && make install

There was a mistake.

./configure compile OK, but make error
Error: ' Php_fe_end ' undeclared here (not in a function)

Workaround:

Source code error, enter php-5.3.17 directory
Sed-i ' s| php_fe_end| {null,null,null}| ' ./ext/**/*.c
Sed-i ' s| zend_mod_end| {null,null,null}| ' ./ext/**/*.c
Re-make && make install

3. A pcntl.so file is generated when the compilation is complete. In the Model directory of PHP

Edit/etc/php.ini, join

Extension=pcntl.so

4. Restart Apache

Service httpd Restart

5. Test whether the installation is successful

Echo Pcntl_fork ();

Output: 23165
