This script causes PHP to crash (sigsegv, return nothing OR to cause
wget to tell "HTTP request sent, awaiting response... End of file while
parsing headers. Retrying.") almost any time. The include.txt file I
used was larger than 100k and was just a simple text. The content of
the file is not important at all, I tried several versions.
<?php
function getMicrotime()
{
list($usec, $sec) = explode(" ", microtime());
return ((float)$usec + (float)$sec);
}
function timer($buffer)
{
global $startTime;
$endTime = getMicrotime();
$diff = sprintf("%.5f", $endTime - $startTime);
return $buffer . "\nExecution time: $diff sec<br>\n";
}
$startTime = getMicrotime();
ob_start("timer");
for ($i = 0; $i < 500; $i++)
{
$fh = fopen("include.txt", "r");
$cmd = fread($fh, 1048576);
fclose($fh);
echo "$i $cmd\n";
}
?>
I compiled PHP with
./configure --prefix=/usr/local/php --disable-short-tags
--enable-safe-mode --enable-ftp --with-mysql=/usr/local/mysql
--with-zlib --enable-memory-limit
