Remove item from array if item value contains searched string character
提问by Nicekiwi
I have an array built from the URL of a webpage.
我有一个从网页的 URL 构建的数组。
If an item in that array contains the ? symbol (The question mark symbol) then I want to remove that item from the array.
如果该数组中的一项包含 ? 符号（问号符号）然后我想从数组中删除该项目。
$array = 'news','artical','?mailchimp=1';
How could I do this? I've seen many examples where the searched string is the whole value, but not where its just a single character or just part of the value.
我怎么能这样做？我见过很多示例，其中搜索到的字符串是整个值，而不是它只是单个字符或值的一部分。
Thanks
谢谢

function myFilter($string) {
return strpos($string, '?') === false;
}
$newArray = array_filter($array, 'myFilter');

foreach($array as $key => $one) {
if(strpos($one, '?') !== false)
unset($array[$key]);
}

Use a closure...
使用闭包...
$array = array_filter($array, function($value){
if (strstr($value, '?') !== false)
{
return false;
}
return true;
});
