In the provided PHP script, why does the comparison of values in the array not yield any matches despite a matching value being present?

The issue is likely due to the strict comparison operator (===) being used in the comparison of values in the array. The strict comparison operator not only compares the values but also checks if the data types are the same. If the data types are different, the comparison will fail even if the values are the same. To solve this issue, you can use the loose comparison operator (==) instead, which only compares the values without checking the data types.

// Original code with issue
$array = [1, 2, '3', 4, 5];
$search_value = '3';

foreach ($array as $value) {
    if ($value === $search_value) {
        echo "Match found!";
    }
}

// Fixed code using loose comparison operator
$array = [1, 2, '3', 4, 5];
$search_value = '3';

foreach ($array as $value) {
    if ($value == $search_value) {
        echo "Match found!";
    }
}
