本代码演示了如何通过PHP的 similar_text函数比较两个字符串的相似性，PHP比较相似字符串，感兴趣的小伙伴，下面一起跟随编程之家 jb51.cc的小编来看看吧。
经测试代码如下：

/**
 * 通过 similar_text函数比较两个字符串的相似性
 *
 * @param 
 * @arrange (编程之家) jb51.cc
 **/
$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%
