使用foreach循环，我们如何用ob_start（）回显数据

Question

We have designed a Progress bar, using Jquery Ui. we need a program that can deliver data in numeric value. That code is not working

PHP CODE

<?php
 ob_start();
 $array = array(10,20,30,40,50,60,70,80,90,100);
 foreach($array as $a ){
echo $a;
 sleep(1);
ob_end_clean();
 }
 echo 100 ;
 ?>

PHP code for echo a single item, it clears the existing data, so that our Ajax program can get the actual numeric data.

Thanks

You need to send a request to your php script with a parameter if you don't have an actual update:

$(function() {
    $("#progressbar").progressbar({ value: 0 });
    setTimeout(function(){ updateProgress(0); }, 500);
});
function updateProgress(data) {
    $.get(url+'?progress='+data, function(data) {
        // data contains whatever that page returns     
        if (data < 100) {
            $("#progressbar").progressbar({value: parseInt(data)});
            $("#progresstext").html("<p>    Loading...<p>");
            setTimeout(function(){ updateProgress(data); }, 500);
        } else {
            $("#progressbar").progressbar({value: 100});
        }
    }); 
}

and your PHP script:

<?php
    echo (int)$_GET['progress']+10;
?>
