本文实例讲述了php比较相似字符串的方法。分享给大家供大家参考。具体分析如下:
这里通过php的similar_text函数比较两个字符串的相似性。
- $word2compare = "stupid";
- $words = array(
- 'stupid',
- 'stu and pid',
- 'hello',
- 'foobar',
- 'stpid',
- 'upid',
- 'stuuupid',
- 'sstuuupiiid',
- );
- while(list($id, $str) = each($words)){
- similar_text($str, $word2compare, $percent);
- print "Comparing '$word2compare' with '$str': ";
- print round($percent) . "%/n";
- }
- /*
- Results:
- Comparing 'stupid' with 'stupid': 100%
- Comparing 'stupid' with 'stu and pid': 71%
- Comparing 'stupid' with 'hello': 0%
- Comparing 'stupid' with 'foobar': 0%
- Comparing 'stupid' with 'stpid': 91%
- Comparing 'stupid' with 'upid': 80%
- Comparing 'stupid' with 'stuuupid': 86%
