问：朋友您好，我正在寻找使用PHP创建进度栏的脚本。请分享您的建议。
答：通过将以下代码放入php文件中，使用以下代码：
<?php
session_start();
ini_set('max_execution_time', 0); // to get unlimited php script execution time
if(empty($_SESSION['i'])){
$_SESSION['i'] = 0;
}
$total = 100;
for($i=$_SESSION['i'];$i<$total;$i++)
{
$_SESSION['i'] = $i;
$percent = intval($i/$total * 100)."%";
sleep(1); // Here call your time taking function like sending bulk sms etc.
echo '<script>
parent.document.getElementById("progressbar").innerHTML="<div style=\"width:'.$percent.';background:linear-gradient(to bottom, rgba(125,126,125,1) 0%,rgba(14,14,14,1) 100%); ;height:35px;\"> </div>";
parent.document.getElementById("information").innerHTML="<div style=\"text-align:center; font-weight:bold\">'.$percent.' is processed.</div>";</script>';
ob_flush();
flush();
}
echo '<script>parent.document.getElementById("information").innerHTML="<div style=\"text-align:center; font-weight:bold\">Process completed</div>"</script>';
session_destroy();
