Description:
------------
str_pad returns the exact same string that was entered as the string input.

str_repeat returns 0 length string.


'./configure' '--localstatedir=/var/hsphere/php' '--with-apxs=/hsphere/shared/apache/bin/apxs' '--with-openssl=/usr' '--with-zlib=/usr' '--with-zlib-dir=/usr' '--with-bz2=/usr' '--enable-calendar' '--with-jpeg-dir=/usr' '--enable-ftp' '--with-gd' '--with-ttf' '--with-freetype-dir=/usr' '--enable-gd-native-ttf' '--with-png-dir=/usr' '--with-gettext=/usr' '--with-imap=/hsphere/shared' '--with-mysql=/usr' '--with-pgsql=/usr' '--with-curl=/hsphere/shared' '--with-curlwrappers' '--with-mhash=/usr' '--with-iconv=/hsphere/shared' '--enable-sockets' '--with-zip=/usr' '--enable-versioning' '--enable-track-vars' '--enable-trans-sid' '--enable-bcmath' '--enable-mbstring' '--disable-debug'

Reproduce code:
---------------
<?php
echo "<br>Start Test!<br>";
echo "<pre>";

var_dump( str_repeat(4, "../") );
echo "\r\n";
var_dump( str_pad("TESTING", 6, "../", STR_PAD_LEFT) );
echo "\r\n";
var_dump( str_pad("TESTING", 6, "-==") );
echo "\r\n";
var_dump( str_pad("TEST", 4) );

echo "</pre>";
echo "<br>End Test!<br>";
exit(0);


?>

Expected result:
----------------
Start Test!

string(0) "../../../../"

string(7) "../../../../../TESTING"

string(7) "TESTING-==-==-==-==-==-=="

string(4) "TEST    "


End Test!

Actual result:
--------------
Start Test!

string(0) ""

string(7) "TESTING"

string(7) "TESTING"

string(4) "TEST"


End Test!
