本文关键字：字符串单词获取 PHP | 更新日期: 2023-09-27

假设我有以下用户DN我需要从下面的字符串中获得唯一的DC字符串和值。

示例1:

CN=xxx,OU=xxx xxx,OU=aaa bbb,DC=ABC,DC=com

结果1:

DC=ABC,DC=com

示例2：由Sam J Levy 创建

OU=Departments,DC=college,DC=school,DC=edu

结果2:

DC=college,DC=school,DC=edu

是否有任何方法可以获得像上面结果那样的整个DC字符串？示例演示

PHP

您可以将substr和strpos组合如下：

<?php
$string = 'CN=xxx,OU=xxx xxx,OU=aaa bbb,DC=ABC,DC=com';
echo substr($string, strpos($string, 'DC='));
?>

输出：

DC=ABC，DC=com

示例2:

<?php
$string = 'OU=Departments,DC=college,DC=school,DC=edu';
echo substr($string, strpos($string, 'DC='));
?>

输出：

DC=学院，DC=学校，DC=教育

JAVASCRIPT

您可以将此strpos函数与substring和length 一起使用

<script>
    
function strpos(haystack, needle, offset) {
  var i = (haystack + '')
    .indexOf(needle, (offset || 0));
  return i === -1 ? false : i;
}
var string = 'CN=xxx,OU=xxx xxx,OU=aaa bbb,DC=ABC,DC=com';
var pos = strpos(string, 'DC=');
var info = string.substring(pos, string.length);
alert(info);
</script>

示例2:

<script>
    
function strpos(haystack, needle, offset) {
  var i = (haystack + '')
    .indexOf(needle, (offset || 0));
  return i === -1 ? false : i;
}
var string = 'OU=Departments,DC=college,DC=school,DC=edu';
var pos = strpos(string, 'DC=');
var info = string.substring(pos, string.length);
alert(info);
</script>
