Bug description: Use of case changing functions in preg_replace produces
unexpected results
Description:
------------
Trying to use preg_replace to change text to uppercase in-between
<uc><uc>. However expected result doesn't occur and the text remains
lowercase. No errors are logged. However adding some text after $1 outputs
this text in uppercase, but the text in-between <uc><uc> remains as
lowercase.
Reproduce code:
---------------
<?
# Test 1: Attempt to replace 'my' with 'MY'
$text = 'this is <uc>my<uc> string';
$text = preg_replace('/\<uc\>(.*)\<uc\>/', strtoupper('$1'), $text);
echo $text.'<br><br>';
# Test 2: Add something after $1 which produces expected output
$text = 'this is <uc>my<uc> string';
$text = preg_replace('/\<uc\>(.*)\<uc\>/', strtoupper('$1 cool'),
$text);
echo $text;
?>
Expected result:
----------------
# Expected result for test 1
this is MY string
# Expected result for test 2
this is MY COOL string
Actual result:
--------------
# Actual result for test 1
this is my string
# Actual result for test 2
this is my COOL string
