#34367 [Opn->Csd]: strange parsing of auto_prepend_file from CmdPrompt

ID: 34367 Updated by: vrana@php.net Reported By: csaba at alum dot mit dot edu -Status: Open +Status: Closed Bug Type: Documentation problem Operating System: Win XP Pro PHP Version: 5CVS-2005-09-04 (CVS) New Comment: This bug has been fixed in the documentation's XML sources. Since the online and downloadable versions of the documentation need some time to get updated, we would like to ask you to be a bit patient. Thank you for the report, and for helping us make our documentation better. -a: "Files included through auto_prepend_file and auto_append_file are parsed in this mode but with some restrictions - e.g. functions have to be defined before called." -r: "This option is meant for a very basic stuff. Thus some configuration directives (e.g. auto_prepend_file and auto_append_file) are ignored in this mode." Previous Comments: ------------------------------------------------------------------------ [2005-09-05 09:56:36] sniper@php.net Need to be documented. -a and -r are really special since they are meant for just very basic stuff. append/prepend scripts are not something like that. ------------------------------------------------------------------------ [2005-09-05 09:54:25] derick@php.net Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php This is expected behavior. Unlike PHP's normal mode where the whole script is parsed first, and then executed - in interactive mode it is done line by line. This means that if you call popup() in line 2, the actual function is not yet defined (as you do that later in line 3). ------------------------------------------------------------------------ [2005-09-04 19:07:41] csaba at alum dot mit dot edu Description: ------------ In a main script file, or included file, or auto_prepend_file it does not matter whether doSomething() is before or after function doSomething() {... does something...} However, this seems broken when the file is an auto_prepend_file and PHP is called from the command line in interactive mode. Specifically, two of the four scenarios below seem incorrect. Scenario 2 is the bug described here, whereas scenario 4 is a separate bug report (Bug 33430). Csaba Gabor from Vienna Reproduce code: --------------- Create a file pop.php (test will only work on a windows system because of the COM component): <?php popup ("inside pop.php"); function popup($text, $title="PHP popup") { $oWSH = new COM("WScript.Shell"); if (is_null($text)) $text = "NULL"; $oWSH->Popup($text, 4, $title, 131120); } ?> Now from the Cmd Prompt do the following 4 tests: 1. php.exe -d auto_prepend_file=pop.php 2. php.exe -d auto_prepend_file=pop.php -a 3. php.exe -d auto_prepend_file=pop.php pop.php 4. php.exe -d auto_prepend_file=pop.php -r print('Hi'); Expected result: ---------------- 1,2: I expect to get a single popup and then have PHP wait for input 3: I expect to get a single popup and then PHP should complain about popup being redifined 4: I should get a single popup and the output should show: Hi Actual result: -------------- 1, 3: As expected 2: The reason for this bug report: PHP dies and complains that it doesn't know what the definition of popup is. Note that if the invocation of popup is moved below the definition, the popup appears as expected. 4. The only thing that happens is that Hi is printed. The auto_prepend_file is not loaded so there is no popup.
