Bug description:stream_get_line return contains delimiter string
Description:
------------
On specific file input stream_get_line returns a "line" that actually
contains the delimiter.
PHP 5.3.10 does not show this problem, PHP versions from 5.3.11 to 5.3.17
do. PHP 5.4.7 seems to be affected as well.
Bug #44607 seems to be related, but was fixed long time ago.
Test script:
---------------
<?php
$file = __DIR__ . '/input_dummy.txt';
$data = str_repeat( '.', 8184 ) . 'MM' . str_repeat( '.', 8190 ) . 'MM' .
str_repeat( '.', 8128 ) . 'MM' . str_repeat( '.', 61 ) . 'MM' . str_repeat(
'.', 20 );
file_put_contents( $file, $data );
$fh = fopen( $file, "rb" );
$delimiter = "MM";
while ( !feof( $fh ) )
{
$before = ftell( $fh );
$line = stream_get_line( $fh, 4096, $delimiter );
$after = ftell( $fh );
if ( strpos( $line, $delimiter ) !== false )
{
echo "found delimiter in return! ($before / $after)\n$line";
exit;
}
}
echo "ok\n";
Expected result:
----------------
ok
Actual result:
--------------
found delimiter in return! (24508 / 24591)
