WINCACHE_LOCK(3)							 1							  WINCACHE_LOCK(3)

wincache_lock - Acquires an exclusive lock on a given key

SYNOPSIS
bool wincache_lock (string $key, [bool $isglobal = false]) DESCRIPTION
Obtains an exclusive lock on a given key. The execution of the current script will be blocked until the lock can be obtained. Once the lock is obtained, the other scripts that try to request the lock by using the same key will be blocked, until the current script releases the lock by using wincache_unlock(3). Warning Using of the wincache_lock(3) and wincache_unlock(3) can cause deadlocks when executing PHP scripts in a multi-process environment like FastCGI. Do not use these functions unless you are absolutely sure you need to use them. For the majority of the operations on the user cache it is not necessary to use these functions. PARAMETERS
o $key - Name of the key in the cache to get the lock on. o $isglobal - Controls whether the scope of the lock is system-wide or local. Local locks are scoped to the application pool in IIS FastCGI case or to all php processes that have the same parent process identifier. RETURN VALUES
Returns TRUE on success or FALSE on failure. EXAMPLES
Example #1 Using wincache_lock(3) <?php $fp = fopen("/tmp/lock.txt", "r+"); if (wincache_lock("lock_txt_lock")) { // do an exclusive lock ftruncate($fp, 0); // truncate file fwrite($fp, "Write something here "); wincache_unlock("lock_txt_lock"); // release the lock } else { echo "Couldn't get the lock!"; } fclose($fp); ?> SEE ALSO
wincache_unlock(3), wincache_ucache_set(3), wincache_ucache_get(3), wincache_ucache_delete(3), wincache_ucache_clear(3), win- cache_ucache_exists(3), wincache_ucache_meminfo(3), wincache_ucache_info(3), wincache_scache_info(3). PHP Documentation Group WINCACHE_LOCK(3)
