"Zend Optimizer" is not installed on the Web Server

[MRatWork]

In php 5.3+ no zend-optimizer but zend-guard-loader. The new one in php 5.5 is opcache.

[chrisf]

Why are you confusing cache mechanism for php with zend decoders?  Opcache has nothing to do with zend guard loader.  And newest version of zend guard loader is for php5.5, zend optimizer was for php5.2 and below.

@enderr, follow my previous reply on installing.  All will work.

[MRatWork]

Zend cache in php 5.2 is zend-optimizer (serve by mratwork because no other repo serve it), in php 5.3 is zend-guard-loader (also serve by mratwork with the same reason) and in php 5.5 is opcache (including in php 5.5 by default).

Why different?. It's because Zend itself change (or produce) different name (or technology) of php cache.

[chrisf]

NO!  You are confusing cache with decoders.

Zend Opcache (ex. Zend Optimizer+)[edit]
Zend Opcache[8] is an open source[9] component of Zend Server and Zend Server Community Edition. Zend Opcache speeds up PHP execution by opcode caching and optimization. It stores precompiled script bytecode in shared memory. This eliminates the stages of reading code from the disk and compiling it on future access. For further performance improvements, the stored bytecode is optimized for faster execution. Unlike Zend Optimizer, Zend Opcache doesn't load files encoded by Zend Guard. Zend provides another component, Zend Guard Loader, in order to load encoded applications with Zend Server and Zend Server Community Edition.

Zend Optimizer+ was renamed to Zend Opcache mid of March 2013.

Starting with PHP 5.5 the Zend Opcache is integrated and shipped with PHP.[10]

Website: http://pecl.php.net/package/ZendOpcache
Sources: https://github.com/zend-dev/ZendOptimizerPlus/
PHP version: full support for PHP 5.2+
Latest stable version: 7.0.2
Status: Actively maintained

Opcache DOES NOT DECODE zend encrypted php files!  Zend guard loader IS THE ONLY decoder for zend encrypted files since php5.3+ AND can run with xcache or opcache as well.

[MRatWork]

I mean Zend produce zend-optimizer in php 5.2 but no produce in php 5.3+ but produce zend-guard-loader.

In php 5.5, opcache already include in php itself.

So finally I did it.
As chrisf sugested the steps are:
1. Download Zend Guard (for php 5.3) from http://www.zend.com/en/products/guard/downloads
2. Unpack archive and upload the module ZendGuardLoader.so to /usr/lib/php/modules/
3. Create a ini file for php integration as in /etc/php.d/zendguard.ini with content

Code: [Select]

; Enable Zend Guard extension module
zend_extension=/usr/lib/php/modules/ZendGuardLoader_53.so
; Enables loading encoded scripts. The default value is On
zend_loader.enable=1
; Disable license checks (for performance reasons)
; zend_loader.disable_licensing=0
; The Obfuscation level supported by Zend Guard Loader. The levels are detailed in the official Zend Guard Documentation. 0 - no obfuscation is enabled
; zend_loader.obfuscation_level_support=3
; Path to where licensed Zend products should look for the product license. For more information on how to create a license file, see the Zend Guard User Guide
; zend_loader.license_path=
5. Restart web services with: sh /script/restart-web
6. The results should look like

Code: [Select]
