How can dynamic arrays be searched for specific values in PHP?

To search for specific values in dynamic arrays in PHP, you can use functions like array_search or in_array. These functions allow you to search for a specific value within an array and return its key or a boolean value indicating its presence. 

// Sample dynamic array
$numbers = [1, 2, 3, 4, 5];

// Search for value 3 in the array
$key = array_search(3, $numbers);

if ($key !== false) {
    echo "Value 3 found at index: " . $key;
} else {
    echo "Value 3 not found in the array";
}

// Another way to search for a value in the array
if (in_array(5, $numbers)) {
    echo "Value 5 is present in the array";
} else {
    echo "Value 5 is not found in the array";
}
