I have been using a software which files are encoded by Zend Guard. Since PHP 5.3 + versions don't support Zend Optimizer hence I have to install Zend Guard Loader to run that application on my windows xampp installation.
I downloaded Zend guard loader and copied to xampp folder.Then I edited the following lines to php.ini file.
zend_extension ="E:\xampp\ZendGuardLoader\php-5.4.x\ZendLoader.dll" zend_loader.enable=1
Then restarted the xampp but it was giving php5.dll missing error then I downloaded php5.dll file from internet and uploaded to xampp/php folder and edited following file xampp\apache\conf\extra\httpd-xampp.conf here I edited this line
to LoadFile "/xampp/php/php5.dll"
then the php5.dll error gone and the following error occurred:
"the procedure entry point zend_new_interned_string could not be located in the dynamic link library E:\xampp\ZendGuardLoader\php-5.4.x\ZendLoader.dll"
When I tried to search on internet then found that this is the issue with 'Thread Safety' is enabled in xampp php. I don't know how to disable 'Thread Safety' or how to use 'Non Thread Safety' php version with xampp.
Please help me to install Zend Guard Loader on Windows 8 os Xampp 1.8.1 with php 5.4.x
