Exemplos

Example #1 SyncSharedMemory::write() example

<?php
// You will probably need to protect shared memory with other synchronization objects.
// Shared memory goes away when the last reference to it disappears.
$mem = new SyncSharedMemory("AppReportName", 1024);
if ($mem->first())
{
    // Do first time initialization work here.
}

$result = $mem->write("report.txt");
var_dump($result);

$result = $mem->write("report.txt", -3);
var_dump($result);
?>

O exemplo acima produzirá algo semelhante a:

int(10)
int(3)
