Bug #23647 pcntl_fork() reruns forked script
Submitted: 2003-05-15 16:31 UTC Modified: 2003-05-15 18:10 UTC

Private report: No CVE-ID: None

The following script:


echo "Hello!";
if (pcntl_fork()) {




Should produce only one "Hello!". The problem is that it appears to restart execution of the script, causing the text "Hello!" to appear twice.

This is _NOT_ how fork() works. The process should continue executing from where the pcntl_fork() function call was issued, and exit the parent process.

Is this related to SA_RESTART and changes made to restart signal handlers in PHP 4.3.0?
