SHM_ATTACH(3) 1 SHM_ATTACH(3) shm_attach - Creates or open a shared memory segment SYNOPSIS
resource shm_attach (int $key, [int $memsize], [int $perm = 0666]) DESCRIPTION
shm_attach(3) returns an id that can be used to access the System V shared memory with the given $key, the first call creates the shared memory segment with $memsize and the optional perm-bits $perm. A second call to shm_attach(3) for the same $key will return a different shared memory identifier, but both identifiers access the same underlying shared memory. $memsize and $perm will be ignored. PARAMETERS
o $key - A numeric shared memory segment ID o $memsize - The memory size. If not provided, default to the sysvshm.init_mem in the php.ini, otherwise 10000 bytes. o $perm - The optional permission bits. Default to 0666. RETURN VALUES
Returns a shared memory segment identifier. CHANGELOG
+--------+---------------------------------------------------+ |Version | | | | | | | Description | | | | +--------+---------------------------------------------------+ | 5.3.0 | | | | | | | This function now returns a resource instead of | | | an integer. | | | | +--------+---------------------------------------------------+ NOTES
Note This function used to return an integer value prior to PHP 5.3.0. To achieve the same value in a portable manner, the return value can be cast to an integer like: Example #1 <?php // Create a temporary file and return its path $tmp = tempnam('/tmp', 'PHP'); // Get the file token key $key = ftok($tmp, 'a'); // Attach the SHM resource, notice the cast afterwards $id = shm_attach($key); if ($id === false) { die('Unable to create the shared memory segment'); } // Cast to integer, since prior to PHP 5.3.0 the resource id // is returned which can be exposed when casting a resource // to an integer $id = (integer) $id; ?> SEE ALSO
