关于PHP正则匹配取出数据的问题

下面是经过一部分处理的源代码

<?php$exam = curl_init("http://exam.hhit.edu.cn/fgquery.do?status=lowquery&tsid=2012120348");curl_setopt($exam, CURLOPT_RETURNTRANSFER, true); // 获取数据返回curl_setopt($exam, CURLOPT_BINARYTRANSFER, true); // 在启用 CURLOPT_RETURNTRANSFER 时候将获取数据返回$exam=curl_exec($exam);        $exam = preg_replace("']*?>'si","",$exam);          $exam = preg_replace("']*?>'si","",$exam);           $exam = preg_replace("']*?>'si","",$exam);           $exam = str_replace("","{tr}",$exam);           $exam = str_replace("","{td}",$exam);           //去掉 HTML 标记            $exam = preg_replace("'<[/!]*?[^<>]*?>'si","",$exam);          //去掉空白字符             $exam = preg_replace("'([rn])[s]+'","",$exam);        $exam = preg_replace('/ /',"",$exam);           $exam = str_replace(" ","",$exam);           $exam = str_replace(" ","",$exam);         $exam = explode('{tr}', $exam);        array_pop($exam);               print_r($exam);?>

[19] => 编号{td}课程{td}日期{td}时间{td}班级{td}考场{td}任课教师{td}[20] => 1{td}流体力学{td}2014-11-0600:00:00.0{td}14:00-16:00{td}土木122{td}Ⅲ-209{td}巩妮娜{td}

回复讨论(解决方案)

你是要这样的

print_r(array_map(null, explode('{td}', $exam[19]), explode('{td}', $exam[20])));

Array(    [0] => Array        (            [0] => 编号            [1] => 1        )    [1] => Array        (            [0] => 课程            [1] => 流体力学        )    [2] => Array        (            [0] => 日期            [1] => 2014-11-0600:00:00.0        )    [3] => Array        (            [0] => 时间            [1] => 14:00-16:00        )    [4] => Array        (            [0] => 班级            [1] => 土木122        )    [5] => Array        (            [0] => 考场            [1] => Ⅲ-209        )    [6] => Array        (            [0] => 任课教师            [1] => 巩妮娜        )    [7] => Array        (            [0] =>             [1] =>         ))

print_r(array_combine(explode('{td}', $exam[19]), explode('{td}', $exam[20])));

Array(    [编号] => 1    [课程] => 流体力学    [日期] => 2014-11-0600:00:00.0    [时间] => 14:00-16:00    [班级] => 土木122    [考场] => Ⅲ-209    [任课教师] => 巩妮娜    [] => )

我想应该是第二种 作为一个数组变量插入到模板中 谢谢大神

版主，可以问个小问题吗？[日期] => 2014-11-0600:00:00.0这个数据在页面上是没有00:00:00.0这些的，能去掉吗？

$s = '2014-11-0600:00:00.0';echo date('Y-m-d', strtotime($s));echo substr($s, 0, 10);

谢谢版主，如此敬业，感激万分，此贴终结！
