Description:
------------
The mb_ereg_search() is regarding $ as end of line rather than end of string.


Reproduce code:
---------------
<?php

$str = " <div>apple\n </div>       \n 		abc     ";
$pattern = "^\s*<div>[\w\W]*?</div>\s*$";

print $str ;


mb_ereg_search_init($str, $pattern, "i");
	if ( mb_ereg_search() ) {
		$r = mb_ereg_search_getregs();

		print_r($r);

		do {
	    	    $cnt++;
	        	$r = mb_ereg_search_regs();
	    }
	    while($r);
	}

?>


Expected result:
----------------
Nothing

Using the default option (ONIG_OPTION_SINGLELINE | ONIG_OPTION_MULTILINE, i.e. 'sm' or 'p') or 's' it no matches, as you expect.

Examples:
<?php

$str = " <div>apple\n </div>       \n 		abc     ";
$pattern = '^\s*<div>[\w\W]*?</div>\s*$';

var_dump(mb_ereg_match($pattern, $str, 'p'));
var_dump(mb_ereg_match($pattern, $str, 's'));
var_dump(mb_ereg_match($pattern, $str, 'si'));
var_dump(mb_ereg_match($pattern, $str, 'm'));
var_dump(mb_ereg_match($pattern, $str, 'mi'));

?>

oniguruma/doc/API says:
  ONIG_OPTION_SINGLELINE: '^' -> '\A', '$' -> '\z', '\Z' -> '\z'

Although, IMHO, SINGLELINE was confused with MULTILINE in this extension.

pcre.org/man.txt:

  \Z - matches at the end of the subject also matches before 
       a newline at the end of the subject
  \z - matches only at the end of the subject


Reclassified -> Doc. problem

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.

"Defaults to 'ms'."
