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。
PHP;">
$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%
*/
希望本文所述对大家的PHP程序设计有所帮助。
