关于PHP中的OOP的澄清

Question

Few of my friend said that traditional way of programming can conflict. For an Example I have created and input box and submit button like this

    <form name="sample" method="post">
    <input type="text" name="name"/>
<input type="submit" />
    </form>
    <?php
    if(isset($_POST['name']){
    $name=$_POST['name'];
    echo $name;}
?>

Now there if three user example tom,jerry and spike enter them name and press submit at the same time is the result can conflict? I have also heard that writing on OOP dose not conflicts. Is it true? If I have to write the same program in OOP the how it will be? Thanks,

Answer 1

As was mentioned, three people submitting a form at the same time will not cause a conflict with what you are doing - simply echoing the inputted value. The way PHP works is to give Tom, Jerry, and Spike each their own $name.

As for an object-oriented approach, the final approach would depend on the scope of your project.

class Person
{
    private $_name;

    public function __construct( $name )
    {
        $this->_name = $name;
    }

    public function WhoAmI()
    {
        echo $this->_name;
    }
}

$myPerson = new Person( $_POST['name'] );
$myPerson->WhoAmI();
