mb_eregi_replace — Replace regular expression with multibyte support ignoring case

说明

mb_eregi_replace(
    string $pattern,
    string $replacement,
    string $string,
    ?string $options = null
): string|false|null

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

参数

pattern: The regular expression pattern. Multibyte characters may be used. The case will be ignored.
replacement: The replacement text.
string: The searched string.
options: The search option. See mb_regex_set_options() for explanation.

返回值

The resultant string or false on error. If string is not valid for the current encoding, null is returned.

更新日志

版本	说明
8.0.0	`options` is nullable now.
7.1.0	The function checks whether `string` is valid for the current encoding.
7.1.0	The `e` modifier has been deprecated.

注释

注意:
mb_regex_encoding() 指定的内部编码或字符编码将会当作此函数用的字符编码。

警告

处理非信任的输入时从不使用 e 修饰符，就不会转码（即调用 preg_replace()）。不注意这些会很可能会导致应用程序引发远程代码执行的漏洞。

To highlight words in multi-byte text:


<?php

$s = 'Алабала';

$f = 'а';

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

?>
