Upgrade php5.2 to php5.4 full record under CentOS (Compile and install), php5.2php5.4

Upgrade

At present, although the latest version of PHP is php5.5, but for various considerations, or first to php5.4 more reliable.
The original PHP used is php5.2.10, has been running for 4-5 years, it is time to upgrade.

5.4 The latest stable version is 5.4.21 (5.4.22 2013 released ...)
Copy the Code code as follows:
wget Http://cn2.php.net/get/php-5.4.21.tar.gz/from/this/mirror
Tar zxf php-5.4.21.tar.gz
CD php-5.4.21

Modify the source code, if the program code is UTF-8, skip this step.

If your program is GBK by default, and there are many programs that use Htmlspecialchars, it is recommended to modify the source code directly, because 5.4 defaults to utf-8. The htmlspecialchars output will be empty.
Copy CodeThe code is as follows:
Ext/standard/html.c
Line 372
/* Default is now UTF-8 */
if (Charset_hint = = NULL)
return cs_utf_8;
--->
/* Default is now UTF-8 */
if (Charset_hint = = NULL)
return cs_8859_1;

Copy CodeThe code is as follows:
wget Http://pecl.php.net/get/ZendOpcache
Tar zxf Zendopcache
CD ZENDOPCACHE-7.0.2/
/usr/local/php5.4/bin/phpize
./configure--with-php-config=/usr/local/php5.4/bin/php-config
