根据2个数字之间的差异多次插入图像。 PHP [英] Inserting an image multiple times based on difference between 2 numbers. PHP

问题描述

处理脚本，计算从API检索的日期之间的差异。我想让它然后放入图像的次数差异。

working on a script, that calculates the difference between dates retrieved from an API. I want it to then drop in an image as many times as the difference.

$d1 = new DateTime('2012-04-04');
$d2 = new DateTime('2012-03-31');

$interval = $d1->diff($d2);

我曾尝试使用for循环，但没有成功

Ive tried to have a go with a for loop but with no success

for ($i = 0 $i <= $interval; $i++) 
{ 
  echo = "<img src=\"test.jpg"/";
}

你们有没有看到任何问题？

can you guys see any problems?

推荐答案

我发现PHP的DateTime在使用modify（）方法而不是普通算术时效果更好。

假设你每天想要一个图像：

I find PHP's DateTime works better when you use the modify() method instead of normal arithmetic.
Assuming you want one image per day:

$d1 = new DateTime('2012-04-04');
$d2 = new DateTime('2012-03-31');    

while($d2 <= $d1)
{
     echo "<img src=\"test.jpg\">";
     $d2->modify("+1 day");
}
