A Warning about undocumented behavior of declare(ticks=1); -- Functions must come first. I took a program that was working and did a substantial rewrite and code reorg. After I was done the program wouldn't run. It kept complaining about undefined functions. After 5 hours of head banging. I finally managed to isolate what specifically had broken my program and then found the following bug entry: http://bugs.php.net/bug.php?id=20924 The problem is that declare(ticks=1); modifies the compilation behavior of php and it introduces an undocumented constraint. When ticks are enabled, you MUST define all of your functions prior to using them. I am spoiled by the ease of forward references and usually prefer to put my functions at the end of the program. But when using ticks you can not do this, the functions must come before the code that calls them. ---- Server IP: 66.163.161.117 Probable Submitter: 63.226.247.49 ---- X-Spam-Status: No, hits=3.1 required=5.0 tests=DATE_MISSING,FROM_NO_LOWER autolearn=no version=2.64 ---- Manual Page -- http://www.php.net/manual/en/ref.pcntl.php Edit -- https://master.php.net/note/edit/69360 Del: integrated -- https://master.php.net/note/delete/69360/integrated Del: useless -- https://master.php.net/note/delete/69360/useless Del: bad code -- https://master.php.net/note/delete/69360/bad+code Del: spam -- https://master.php.net/note/delete/69360/spam Del: non-english -- https://master.php.net/note/delete/69360/non-english Del: in docs -- https://master.php.net/note/delete/69360/in+docs Del: other reasons-- https://master.php.net/note/delete/69360 Reject -- https://master.php.net/note/reject/69360 Search -- https://master.php.net/manage/user-notes.php
