shm_attach
SHM_ATTACH(3) 1 SHM_ATTACH(3)shm_attach - Creates or open a shared memory segmentSYNOPSIS
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.

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;
?>
