SAPIs are different runtime environments of PHP.

mod_php NTS

(non-thread safety) Contained in the php56w package, this SAPI integrates inkhổng lồ Apache Httpd (2.2.* on RHEL/CentOS 6, 2.4.* on RHEL/CentOS 7). It is the standard SAPI for use with httpd prefork mpm (the mặc định mode httpd is ran under. It is not thread-safe, but doesn’t need to lớn be due lớn prefork not using threads. It’s located at /usr/lib<64>/httpd/modules/


Contained in the php56w-cli package, this SAPI allows running scripts from the command-line, and also has a built-in web VPS for development-use. Located at /usr/bin/php


Contained in the php56w-fpm package, fpm (FastCGI Process Manager) is a scalable FastCGI process, which acts similar to lớn how Httpd prefork mpm works managing it’s forks. Located at /usr/sbin/php-fpm, it is controlled using the /etc/init.d/php-fpm service script


Contained in the php56w-phpdbg package, phpdbg has the ability to debug scripts using breakpoints from the command-line, và also supports remote-debugging using an external Java client for remote communication.


Contained in the php56w-embedded package, this SAPI allows embedding PHPhường in other applications. It’s library is located at /usr/lib<64>/

cgi, fastcgi

Contained in the php56w-cli package, these SAPIs are not recommended for use, but are available where needed. They both exist in the binary at /usr/bin/php-cgi.

mod_php TS

(thread safety) Contained in the php56w package, this SAPI integrates into lớn Apabít Httpd (2.2.* on RHEL/CentOS 6, 2.4.* on RHEL/CentOS 7). It is the standard SAPI for use with httpd worker mpm. It’s supposed lớn be thread-safe, but can’t guarantee lớn be, và certainly not under additional PHPhường. extensions. It’s better to use FastCGI SAPIs than this one. It’s located at /usr/lib<64>/httpd/modules/

The PHP distribution now comes with an opcode cache. This is the Zend Optimizer+opcode cache, now known as the Zkết thúc OPcabít extension. This extension isoptional, so does not preclude you from using an alternate one.

Due to lớn it being included in the PHP. source distribution, it will be wellmaintained and more suitable for use while other Opcode cache’s are beingupdated over the coming months.

error_reporting E_ALL includes E_STRICT

As mentioned in the PHPhường 5.4 guide:

You may get a lot more errors coming out of your error logs if by default yourerror_reporting is set lớn E_ALL now without explicitly turning off E_STRICT. Themặc định php.ini that comes with the PHPhường. package turns this off by default, butif you are upgrading from an existing installation, your php.ini may not beupdated, meaning this will likely be turned on.
