How can values be retrieved from a while loop in PHP and used outside of the loop?

To retrieve values from a while loop in PHP and use them outside of the loop, you can store the values in an array or variable during each iteration of the loop. Once the loop has finished executing, you can access these stored values outside of the loop. 

$values = array();

while ($condition) {
    // Perform some operations
    $value = getValue(); // Retrieve value from the loop
    $values[] = $value; // Store the value in an array
}

// Values can now be accessed outside of the loop
foreach ($values as $val) {
    echo $val . "<br>";
}
