PHP 7.0.6 Released

    mb_eregi_replace

    (PHP 4 >= 4.2.0, PHP 5, PHP 7)

    mb_eregi_replace — Replace regular expression with multibyte support ignoring case

    Description

    string mb_eregi_replace ( string $pattern , string $replace , string $string [, string $option = "msri" ] )

    Scans string for matches to pattern, then replaces the matched text with replacement.

    Parameters

    pattern

    The regular expression pattern. Multibyte characters may be used. The case will be ignored.

    replace

    The replacement text.

    string

    The searched string.

    option
    option has the same meaning as in mb_ereg_replace().

    Return Values

    The resultant string or FALSE on error.

    Notes

    Note:

    The internal encoding or the character encoding specified by mb_regex_encoding() will be used as the character encoding for this function.

    Warning

    Never use the e modifier when working on untrusted input. No automatic escaping will happen (as known from preg_replace()). Not taking care of this will most likely create remote code execution vulnerabilities in your application.

    $s     = 'Алабала';
    $f = 'а';
    echo     preg_replace('/('.$f.')/iu', '<b>$1</b>', $s);

    when trying to find a way to strip newline from a multibyte UTF-8 string i got to this function just to discover later that POSIX don't "do" newline so i can't strip them, examples of what i tried are : \r\n , \\r\\n , (\\r\\n) (\\r|\\n)

    and got no result
    so since i wanted something like mb_nl2br() that's simple i wrote this little recursive function for UTF-8:

    <?php
    function mb_str_replace($find,$replace,&$str)
    {
    $i = mb_strpos($str,$find, 0,"UTF-8");
    if (    $index===false) {return;}
    $str = mb_substr($str, 0,$i).$replace.mb_substr($str, $i+mb_strlen($find,"UTF-8"),mb_strlen($str,"UTF-8"));
    $this->mb_str_replace($find,$replace,$str);
    }
    ?>

    note: moderate unit tesing was done, changed to other encodings
