I installed both Zend CE and zend debugger of Eclipse on my Mac. Both of them work well in Mac lion. However they don’t work any more after I upgraded my Mac to mountain lion.
After some investigation I found some extensions of Zend PHP can’t be loaded due to shared library dependency can’t be found in mountain lion. The xslt module of PHP depends on some system libraries(suc as /usr/local/libxslt-1.1.23/lib/libxslt.1.dylib) that have been removed by mountain lion.
The temporary solution is disabling xlst module of zend PHP if your application doesn’t need them.
The workaround fix of Zend CE on Mac,
rename /usr/local/zend/lib/php_extensions/xsl.so to any other name
The workaround fix of zend debugger for Eclipse,
Delete the line extension=xsl.so from file **
/plugins/org.zend.php.debug.debugger.macosx_5.3.18.v20110322/resources/php53/php.ini**
