php比较相似字符串的方法

　　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%

Comparing 'stupid' with 'sstuuupiiid': 71%
