Replace regular expression with multibyte support

说明

string mb_ereg_replace ( string $pattern , string $replacement , string $string [, string $option = "msr" ] )

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 in pattern.

replacement

The replacement text.

string

The string being checked.

option

Matching condition can be set by option parameter. If i is specified for this parameter, the case will be ignored. If x is specified, white space will be ignored. If m is specified, match will be executed in multiline mode and line break will be included in '.'. If p is specified, match will be executed in POSIX mode, line break will be considered as normal character. If e is specified, replacement string will be evaluated as PHP expression.

返回值

The resultant string on success, or FALSE on error.

注释

Note:
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。

Warning

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。

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.
