I wanted t play around with the CGI (not CLI) version of PHP and get a
feel for the I/O stuff, specifically STDIN. So I whipped up the
following script:
///////////////////////////////////////////////////////////////////
#!/usr/bin/php -qC
<?
if( ($stdin = fopen( 'php://stdin', 'r' )) === false )
{
echo 'Failed to open STDIN'."\n";
exit();
}
stream_set_blocking( $stdin, false );
$count = 0;
while( 1 )
{
echo 'Foo: '.($count++)."\n";
if( ($char = fread( $stdin, 1 )) !== false )
{
echo $char."\n";
}
else
{
echo 'Fooo!'."\n";
}
}
////////////////////////////////////////////////////////////////////
Simple enough right?! The problem is the program exits seemingly
randomly. The last value for $foo can be anywhere from 400 to 1500. Even
more strange is that running it through gdb indicates a successful exit,
with no problems or core dumps. Anyone had any similar experiences? I'm
running PHP 4.3.3 (cgi) -- the latest download version.
Cheers,
Rob.
