PHP Bug Type: mbstring related
Bug description: mb_ereg returns byte length of string instead of character
length
Description:
------------
When the $regs argument is provided, mb_ereg will return the length of the
matched string. The integer returned though is the byte length of the
string instead of the character length, which seems illogical for a
multibyte string function.
Reproduce code:
---------------
<?php
mb_regex_encoding('utf-8');
$string_mb =
base64_decode('5pel5pys6Kqe44OG44Kt44K544OI44Gn44GZ44CCMDEyMzTvvJXvvJbvvJfvvJjvvJnjgII=');
$regex = '^.*?[[:blank:]]?[[:punct:][:digit:]]+\.?$';
echo "\nMultibyte String without \$regs arg:\t";
var_dump(mb_ereg($regex, $string_mb));
echo "Multubyte String with \$regs arg:\t";
var_dump(mb_ereg($regex, $string_mb, $regs_mb));
echo "Character length of matched string:\t";
var_dump(mb_strlen($regs_mb[0], 'utf-8'));
?>
Expected result:
----------------
Multibyte String without $regs arg: int(1)
Multubyte String with $regs arg: int(21)
Character length of matched string: int(21)
Actual result:
--------------
Multibyte String without $regs arg: int(1)
Multubyte String with $regs arg: int(53)
Character length of matched string: int(21)
