Actually i do not know how to install this package. As am said am using xampp 1.5.4 version. I downloaded APC from
http://pecl.php.net/package/APC and i unpacked into "xampp/php" folder. Also i added below lines in php.ini and restarted apache.
extension=php_apc.dll
extension=apc.so
apc.enabled=1
apc.shm_segments=1
apc.shm_size=128
apc.ttl=7200
apc.user_ttl=7200
apc.num_files_hint=1024
apc.mmap_file_mask=/tmp/apc.XXXXXX
apc.enable_cli=1
and i enabled extension=php_mcrypt.dll,extension=php_mcrypt_filter.dll,extension=php_memcache.dll by removing ";" in front
finally When am testing with print_r(apc_cache_info()); i got
Fatal error: Call to undefined function apc_cache_info() in D:\Program Files\xampp\htdocs\setup\info.php on line 2
I seen there is pecl.bat file in xampp/php folder. But i do not know how to use
