note 56740 added to function.exec

I had to combine many PDFs into a single one using pdftk and did this by writing the commands into a batch file and running it with exec('cmd /c blabla.cmd'). Using batch files under Windows, there's a line-length-limit of 1024 characters. So I made sure each line in the batch file doesn't exceed 1024 characters. I now switched over to using exec('start /b ...') directly with the desired command (instead of writing it into a batch file and calling that) and played around with the line-length. Seems like the exec() command works with command-strings of up to 4096 characters in length. If the string is longer, it won't be executed. ---- Manual Page -- http://www.php.net/manual/en/function.exec.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+56740 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+56740&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+56740&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+56740&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+56740&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+56740&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+56740&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+56740&report=yes Search -- http://master.php.net/manage/user-notes.php
