Question

Hi I’m working on a checking a given array for a certain value.

my array looks like

while($row = mysqli_fetch_array($result)){

    $positions[] = array( 'pos' => $row['pos'], 'mark' => $row['mark'] );
}

I’m trying to get the info from it with a method like

<?php
    if(in_array('1', $positions)){
          echo "x";
    }
?>

This I know the value ‘1’ is in the array but the x isn’t being sent as out put. any suggestions on how to get “1” to be recognized as being in the array?

Edit:
I realize that this is an array inside of an array. is it possible to combine in_array() to say something like:
“is the value ‘1’ inside one of these arrays”

Answer 1

in_array is not recursive. You’re checking if 1 is in an array of arrays which doesn’t make sense. You’ll have to loop over each element and check that way.

$in = false;
foreach ($positions as $pos) {
    if (in_array(1, $pos)) {
        $in = true;
        break;
    }
}
