pcntl extension can support multi-threaded operation of php (linux only)

Originally, you need to recompile PHP and add --enable-pcntl to the configure prompt later

Since my php is installed using yum, I cannot use the above Method

The following introduces a way to dynamically add extensions to phpize

1. First look at the directory where the phpize command is located (ps: my directory/usr/bin/phpize)

If not found, execute the installation

yum install php53_devel  (ps:请注意自己的版本)
Copy after login

After installation is completed. The phpize command will be generated

2. Go to php.net to download the corresponding version of the php source file

Let’s take php-5.3.17 as an example. After unzipping, enter the corresponding module

cd ext/pcntl
#先执行phpize
/usr/bin/phpize
./configure --with-php-config=/usr/bin/php-config  (ps:请正确的指定php-config的目录)
#编译、安装
make && make install
Copy after login

At this time An error occurred

./configure compiled normally, but make error
error: 'PHP_FE_END' undeclared here (not in a function)

Solution:

There is an error in the source code, enter the 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. It will be generated after compilation is completed A pcntl.so file was created. Edit /etc/php.ini in the php model directory and add


extension=pcntl.so

4. Restart apache

service httpd restart

5. Test whether the installation is successful

<?php
  echo pcntl_fork();
?>
Copy after login

Output: 23165
