Doc #66769 [Com]: sleep function wrong definition

Edit report at https://bugs.php.net/bug.php?id=66769&edit=1 ID: 66769 Comment by: keithm at aoeex dot com Reported by: aryans dot vinay at gmail dot com Summary: sleep function wrong definition Status: Open Type: Documentation Problem Package: Documentation problem Operating System: any PHP Version: Irrelevant Block user comment: N Private report: N New Comment: Sleep does not block other instances of the script. Here's a snippet of ab output using your test script: --- Concurrency Level: 10 Time taken for tests: 4.246 seconds Complete requests: 10 --- All 10 requests were completed in just 4.246 seconds. You probably have some other element causing your scripts to depend on each other which is then causing a sleep in one script to delay the others. For example if your scripts all use sessions this can happen. With the default file-based sessions, calling session_start() will lock the session file. Any other scripts trying to call session_start() referencing that same file will block until the first script closes the file by either terminating or calling session_write_close(). So calling sleep() in a script that is using the session would cause other scripts to be delayed by the sleep duration due to the lock on the session file, not due to how sleep() works.

Please fix the words in documetation. Thanks :) Test script: --------------- <?php sleep(2); echo "Hello"; ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=66769&edit=1
