jQuery AJAX从PHP获取

Question

I have this php and js file

PHP

<?php
    $user_id = '10';
    echo $user_id;
?>

JS

$(document).ready(function() {
            $.ajax({
                url:"uid.php",
                success:function(data){
                    alert(data);
}
});
});

I get "10" as alert

However for this PHP and JS there is no alert

PHP

<?php
class uidclass{
function uid_func($event, $arguments)
{
    $user_id = '10';
    echo $user_id;
}
}
?>

JS

$(document).ready(function() {
            $.ajax({
                url:"uid.php",
                success:function(data){
                    alert(data);
}
});
});

Thanks in advance

You need to use the class and method properly

<?php
class uidclass{
    function uid_func($event, $arguments) {
        $user_id = '10';
        echo $user_id;
    }
}

$bob = new uidclass;
$bob->uid_func(null,null); // since the parameters are not defined

or like this

<?php
class uidclass{
    function uid_func($event = null, $arguments = null) {
        $user_id = '10';
        return $user_id;
    }
}

$bob = new uidclass;
print $bob->uid_func(); // we have already set defaults in the function definition

or even add a constructor and print inside the method

<?php
class uidclass{
    public function uid_func($event = null, $arguments = null) {
        $user_id = '10';
        print $user_id;
    }
    public function __construct() {
        $this->uid_func();
    }
}

$bob = new uidclass();
