PHP multi-thread extension (main thread) pthreads Installation

Environment CentOS 6.3 64bit, php 5.4.5 pthreads need thread security environment, download the php installation package, unzip: tar zxvf php-5.4.5.tar.gz // name is not this I'm not sure, go to download and install myself :. /configure -- enable-zts -- prefix =/usr/local/php-zts make install. Then, install php of the thread-installed version to/usr/local/php-zts, currently, I do not know the impact of enabling thread security. Therefore, I have two test versions. Download and install pthreads: tar zxvf pthreads cd pthreads-0.0.45 // This article is the first stable version/usr/local/php-zts/bin/phpize. /configure -- with-php-config =/usr/local/php-zts/bin/php-configmakemake install/usr/local/php-zts/bin/php-I | grep "php. ini "find php. ini location, modify it to ext = pthreads. so is added in, because I already have php, and now the newly installed php. if the INI file does not exist, I got a pass ...... Some sample files in the pthreads-0.0.45/examples directory are more useful than the document. The online document cannot describe the problem at all. I modified one and executed it:
