如何在php中回送循环并将其放入变量中？
嗨，我在从php发送数据到pdf时遇到问题。我认为唯一的方法是将数据放入一个变量，该变量将被发送到pdf函数。 下面是我需要放入php变量中的代码如何在php中回送循环并将其放入变量中？,php,javascript,jquery,ajax,Php,Javascript,Jquery,Ajax,嗨，我在从php发送数据到pdf时遇到问题。我认为唯一的方法是将数据放入一个变量，该变量将被发送到pdf函数。 下面是我需要放入php变量中的代码 <table width="95%" height="95%"> <tr> <td align="center"> <table width="100%" border="0" cellpadding="2" cell

虽然我不完全明白你在问什么，但我会尽力回答的 如果您希望当前使用PHP在变量中显示页面的所有内容，而不是使用echo，那么您需要将这些信息附加到变量中，因此
<?php
$timestamp = mktime(0,0,0,$cMonth,1,$cYear);
$maxday = date("t",$timestamp);
$thismonth = getdate ($timestamp);
$startday = $thismonth['wday'];

$day = '0'.$day;
}else{
$day = $day;
}
$date = $monthNames[$cMonth-1].' '.$day.', '.$cYear;

现在，您可以使用$send\u me\u to\u pdf作为pdf函数的参数，在其中发送数据？虽然我不完全理解您的问题，但我会尝试回答 如果您希望当前使用PHP在变量中显示页面的所有内容，而不是使用echo，那么您需要将这些信息附加到变量中，因此

现在，您可以使用$send_me_to_pdf作为pdf函数的参数，在其中发送数据？如果您有一大块HTML/PHP，并且需要将输出存储在变量中而不是打印到屏幕上，您可以使用函数来简化此过程：
<?php
ob_start(); // Start the buffer (nothing will be output)
?>
