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";
$words=array(
'stupid',
'stuandpid',
'hello',
'foobar',
'stpid',
'upid',
'stuuupid',
'sstuuupiiid',
);
while(list($id,$str)=each($words)){
similar_text($str,$word2compare,$percent);
print"Comparing'$word2compare'with'$str':";
printround($percent)."%\n";
}
/*
Results:
Comparing'stupid'with'stupid':100%
Comparing'stupid'with'stuandpid':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%
