The main content of this article is to explain "what are the php intercept string functions that support Chinese and other codes", interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn what are the php intercept string functions that support Chinese and other codes.

A simple string interception method that supports Chinese and other encodings. Just pass in the corresponding parameters and call them directly.

The copy code is as follows:

/ * *

* string interception, which supports Chinese and other encodings

* @ static

* @ access public

* @ param string $str string to be converted

* @ param string $start start position

* @ param string $length intercept length

* @ param string $charset encoding format

* @ param string $suffix truncate display characters

* @ return string

, /

Function msubstr ($str, $start=0, $length, $charset= "utf-8", $suffix=true) {

If (function_exists ("mb_substr"))

$slice = mb_substr ($str, $start, $length, $charset)

Elseif (function_exists ('iconv_substr')) {

$slice = iconv_substr ($str,$start,$length,$charset)

If (false = = $slice) {

$slice =''

}

} else {

$re ['utf-8'] = "/ [\ x01 -\ x7f] | [\ xc2-\ xdf] [\ x80 -\ xbf] | [\ xe0-\ xef] [\ x80 -\ xbf] {2} | [\ xf0-\ xff] [\ x80 -\ xbf] {3} /"

$re ['gb2312'] = "/ [\ x01 -\ x7f] | [\ xb0-\ xf7] [\ xa0-\ xfe] /"

$re ['gbk'] = "/ [\ x01 -\ x7f] | [\ x81 -\ xfe] [\ x40 -\ xfe] /"

$re ['big5'] = "/ [\ x01 -\ x7f] | [\ x81 -\ xfe] ([\ x40 -\ x7e] |\ xa1-\ xfe]) /"

Preg_match_all ($re [$charset], $str, $match)

$slice = join ("", array_slice ($match [0], $start, $length))

}

Return $suffix? $slice.'...': $slice

}
