Bug description: ereg_replace does not replace all occurrences
Description:
------------
ereg_replace() does not replace all occurrences of a regular expression as
the following example shows. The pattern
&([^;][^;][^;][^;][^;])
is replaced with
&\\1
in a string
http://search.networkworld.com/index.html?col=&qs=&qc=&si=0&ql=a&nh=25&lk=1&rf=0qqqqqqqqqqqq
The output is
http://search.networkworld.com/index.html?col=&qs=&qc=&si=0&ql=a&nh=25&lk=1&rf=0qqqqqqqqqqqq
which indicates for example that the last & was not replaced.
Reproduce code:
---------------
<?php
$data =
"http://search.networkworld.com/index.html?col=&qs=&qc=&si=0&ql=a&nh=25&lk=1&rf=0qqqqqqqqqqqq";
$pattern="&([^;][^;][^;][^;][^;])";
$data=ereg_replace($pattern, "&\\1", $data);
echo $data."\n";
//
http://search.networkworld.com/index.html?col=&qs=&qc=&si=0&ql=a&nh=25&lk=1&rf=0qqqqqqqqqqqq
$data=ereg_replace($pattern, "&\\1", $data);
echo $data."\n";
//
http://search.networkworld.com/index.html?col=&qs=&qc=&si=0&ql=a&nh=25&lk=1&rf=0qqqqqqqqqqqq
?>
Expected result:
----------------
http://search.networkworld.com/index.html?col=&qs=&qc=&si=0&ql=a&nh=25&lk=1&rf=0qqqqqqqqqqqq
Actual result:
--------------
http://search.networkworld.com/index.html?col=&qs=&qc=&si=0&ql=a&nh=25&lk=1&rf=0qqqqqqqqqqqq
