问题描述
我正在尝试检测一个字符串是否包含至少一个存储在数组中的URL.
I am trying to detect whether a string contains at least one URL that is stored in an array.
这是我的数组:
$owned_urls = array('website1.com', 'website2.com', 'website3.com');
该字符串由用户输入并通过PHP提交.在确认页面上,我想检查输入的URL是否在数组中.
The string is entered by the user and submitted via PHP. On the confirmation page I would like to check if the URL entered is in the array.
我尝试了以下操作:
$string = 'my domain name is website3.com';
if (in_array($string, $owned_urls))
{
echo "Match found";
return true;
}
else
{
echo "Match not found";
return false;
}
无论输入什么,返回值始终为找不到匹配项".
No matter what is inputted the return is always "Match not found".
这是正确的做事方式吗?
Is this the correct way of doing things?
推荐答案
尝试一下.
$string = 'my domain name is website3.com';
foreach ($owned_urls as $url) {
//if (strstr($string, $url)) { // mine version
if (strpos($string, $url) !== FALSE) { // Yoshi version
echo "Match found";
return true;
}
}
echo "Not found!";
return false;
使用 stristr()或,如果您要检查不区分大小写的内容.
Use stristr() or stripos() if you want to check case-insensitive.
