检查$ _COOKIE的内容是否有字符串

Question

When I run var_dump($_COOKIE) I get the following output:

array(9) {
    ["wordpress_test_cookie"] => string(15)
    "WP Cookie check" 
    ["wp-postpass_299da1fd9cb967a93782c5397fa3a35e"] => string(34)
    "$P$BXtsZ0i1qom3bqiFk4b9GeG8l9dFVG." 
}

I want to check the contents of $_COOKIE for the existence of wp-postpass_ elements.

I tried: if(strpos($_COOKIE,'wp-postpass_') === 0) { but this didn't work.

Where am I going wrong?

Thank you

Answer 1

if(isset($_COOKIE)){
    foreach($_COOKIE as $key=>$val){
        if(strpos($key,'wp-postpass_') === false) {
        //not found
        }else{
        //found
        }
    }
}
