Question

Within a PHP foreach loop I have a person’s name looping. However, outside the loop I want to determine the largest length used within the loop. So I may have 6 names in the loop and most of them may be 6-8 characters long, but one might be 12 characters. So I would like to find the largest amount.

Answer 1

$info = array();

$names = array("Name 1","Name 2","Name 3","This is the longest string","Name 4");

foreach($names as $key=>$value) {
    if(empty($info) || strlen($value) > $info[1]) {
        $info[0] = $key;
        $info[1] = strlen($value);
    }
}

echo 'The longest value is ', $names[$info[0]], ' which has ', $info[1], ' charachters and its array index is ', $info[0];
