代码如下:



四位.club 域名



/*
test.txt 文件内容为:

10ferents.club
1901.club
1992.club
288cash.club
2nd.club
365gold.club
3dscanning.club
406disco.club
99fitness.club
abuo9i8n3.club
abuo9i8n5.club
abur5t6b2.club
abut6y7n1.club
abut6y7n4.club
abut6y7n7.club
abuy7u8n6.club
1234.club
abcd.club

4.txt 只有:
abcd.club

正确的答案应该是:
1901.club
1992.club
1234.club
abcd.club
*/
$handle=fopen("test.txt","r");
while(!feof($handle)){
$str=fgets($handle);
if(stripos($str,".")==4){
file_put_contents("4.txt",$str);
}
}
?>




筛选域名用的,但是结果怎么只显示一行啊,用
echo $str."
\n";显示结果在正常的.

筛选域名用的,但是结果怎么只显示一行啊,用
echo $str."
\n";显示结果在正常的.

这样:

<code>$str = fgets($handle); 
$str = trim($str);</code>
Copy after login

不知道的怎么解决的时候,请

<code>var_dump(stripos($str,"."));
</code>
Copy after login

看看是否是4

还有追加写入:

<code>file_put_contents("4.txt",$str, FILE_APPEND);</code>
Copy after login

写了个DEMO,用正则匹配的

<code>$str = '10ferents.club 
1901.club 
1992.club 
288cash.club 
2nd.club 
365gold.club 
3dscanning.club 
406disco.club 
99fitness.club 
abuo9i8n3.club 
abuo9i8n5.club 
abur5t6b2.club 
abut6y7n1.club 
abut6y7n4.club 
abut6y7n7.club 
abuy7u8n6.club 
1234.club 
abcd.club';
preg_match_all('/[0-9a-z-]{4}/', $str, $arr);
$string = implode("\n", $arr[0]);
file_put_contents('1.txt', $string);
</code>
Copy after login

file_put_contents每次都会覆盖掉之前的,应该用fwrite追加写入

file_put_contents("4.txt",$str,FILE_APPEND);

fopen("test.txt","a")
