note 48859 added to ref.exec

Just to clarify, background shell exec()ing is not the same as a fork() under Unix. It would be useful if PHP supported fork() like Perl and other scripting languages do. Simply exec()'ing a process and sending it to the background is not the same. A true fork() copies the current environment and duplicates the running script so that there are two instances, one child, one parent. The child and parent can determine which copy they are and then take separate courses of execution paths based on that. Often one copy will perform some "busy work" while the other returns to normal execution. But no matter what, both functions live within the same code rather than a separate, external program. exec()ing can not do this for you. ---- Manual Page -- http://www.php.net/manual/en/ref.exec.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+48859 Delete -- http://master.php.net/manage/user-notes.php?action=delete+48859&report=yes Reason: bad code -- http://master.php.net/manage/user-notes.php?action=delete+48859&report=yes&reason=bad+code Reason: spam -- http://master.php.net/manage/user-notes.php?action=delete+48859&report=yes&reason=spam Reason: useless example -- http://master.php.net/manage/user-notes.php?action=delete+48859&report=yes&reason=useless+example Reason: contains commercial links -- http://master.php.net/manage/user-notes.php?action=delete+48859&report=yes&reason=contains+commercial+links Reason: useless note -- http://master.php.net/manage/user-notes.php?action=delete+48859&report=yes&reason=useless+note Reject -- http://master.php.net/manage/user-notes.php?action=reject+48859&report=yes Search -- http://master.php.net/manage/user-notes.php
