Description:
------------
The test script should end with a second "Return to Menu" line.  But the built-in web server does not output the last 2 lines of the page.
If you remove the comment so that MAXROWS is 1 instead of 2, it works fine.
Turning output buffering off in php.ini has no effect

Test script:
---------------
<?php
//define("MAXROWS", 1); //Uncomment this line to see the second Return to Menu line appear in the output
if (!defined("MAXROWS")) define("MAXROWS", 2);
$results = '<table border="1">' . PHP_EOL . '<tr><th scope="col" style="text-align:center">#</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah blah</th><th scope="col" style="text-align:center">Blah&nbsp;blah&nbsp;blah&nbsp;blah&nbsp;blah&nbsp;blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah&nbsp;blah&nbsp;blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah&nbsp;blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah&nbsp;blah&nbsp;blah&nbsp;blah&nbsp;blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah&nbsp;blah&nbsp;blah&nbsp;blah&nbsp;blah</th><th scope="col" style="text-align:center">Blah</th><th scope="col" style="text-align:center">Blah&nbsp;blah&nbsp;blah&nbsp;blah&nbsp;blah</th><th scope="col" style="text-align:center">Blah</th></tr>';

Test script had lines truncated.  Will try to upload as a patch.

[2011-10-26 22:56 UTC] david dot gero at ec dot gc dot ca

Okay, your bug system has me stumped.  Can't upload the test script, because I get the following:

Error: uploaded patch file must be text file (save as e.g. "patch.txt" or "package.diff") (detected "text/x-php")
Could not attach patch "testflush.php" to Bug #60146

Interesting bug that "text/x-php" is not considered text.
The test script is only 20 lines, but some of them are long.

Email me with a good return address and I will send the test script to you.  Or maybe you could tell me how I'm supposed to upload it.

[2011-10-27 09:50 UTC] laruence@php.net

and, I can't reproduce this in my environ with your test script pasted above.
plz check your php error log, if there is some error. thanks

[2011-10-27 14:33 UTC] david dot gero at ec dot gc dot ca

Renaming to testflush.txt gives the following:

Error: uploaded patch file must be text file (save as e.g. "patch.txt" or "package.diff") (detected "text/x-php")
Could not attach patch "testflush.txt" to Bug #60146

Your upload system is scanning inside the file, probably using the "file" command, which indeed gives type "text/x-php", regardless of the extension.  However why this is not accepted as text by your system is a mystery, and a bug in itself.

I will email you the script, and hope you can figure out how to upload it.

Looks like I was wrong about the test script being truncated above.  Just didn't scroll far enough to the right.

So, if you can't reproduce, whereas it fails every time for me, I've uploaded my php.ini file.

There are no errors in php_error.log

I'm testing on Windows XP with Service Pack 3, running the following startup.cmd:

@echo off
title PHP
start "PHP" /MAX php -S 127.0.0.1:8000 -t \repos\gerod\html
exit

testflush.php is in \repos\gerod\html\admin\testflush.php

Using Internet Explorer 7 at http://localhost:8000/admin/testflush.php

Page->View Source shows that the last two lines were never output

[2011-10-27 18:06 UTC] david dot gero at ec dot gc dot ca

Tried using curl from cygwin to access the page, and the last two lines are missing the same way, so the problem is not Internet Explorer
