PHP＆＃34; for循环＆＃34;收集数据

Question

如何循环这个东西来收集多个$ objectId的数据？例如从$ objectId 1038到1048。

在Im presentig可以收集数据的完整脚本。行$objectId = ""; //I want to gather info about IDs lets say from 1038 - 1048应该是我认为的循环，但我没有做好。

<form name="myForm" action="" method="post" id="myForm">
  <table cellpadding="2" border="1">
    <tr>
      <td width="264" rowspan="2" valign="top"><?php 

    function transformHTML($string)
    {
        $string = trim($string);
        $string = utf8_decode($string);
        $string = htmlentities($string, ENT_NOQUOTES);
        $string = str_replace("#", "&#35;", $string);
        $string = str_replace("%", "&#37;", $string);

        return $string;
    }

    function get_string_between($string, $start, $end){
        $string = " ".$string;
        $ini = strpos($string,$start);
        if ($ini == 0) return "";
        $ini += strlen($start);
        $len = strpos($string,$end,$ini) - $ini;
        return substr($string,$ini,$len);
    }

    if($_POST['submit']) { 

        $objectId = ""; //I want to gather info about IDs lets say from 1038 - 1048
