在PHP中匹配通配符数组 - WordPress

Question

PHP code:

$search = "Who is KMichaele test";
$array = ["john","michael","adam"];

if (in_array($search, $array)) {
echo "success";
}
else
echo "fail";

I want the success output. How is it possible?

You can use array_reduce and stripos to check all the values in $array to see if they are present in $search in a case-insensitive manner:

$search = "Who is KMichaele test";
$array = ["john","michael","adam"];

if (array_reduce($array, 
                 function ($c, $i) use ($search) {
                     return $c || (stripos($search, $i) !== false);
                 },
                 false))
    echo "success";
else
    echo "fail";

Output:

success

Edit

Since this is probably more useful wrapped in a function, here's how to do that:

$search = "Who is KMichaele test";
$array = ["john","michael","adam"];

function search($array, $search) {
    return array_reduce($array, 
                         function ($c, $i) use ($search) {
                             return $c || (stripos($search, $i) !== false);
                         },
                         false);
}

if (search($array, $search))
    echo "success";
else
    echo "fail";

$search2 = "michael";
if (search($array, $search2))
    echo "success";
else
    echo "fail";

Output

success
success
