通过数组迭代并使用PHP动态地将值添加到HTML

Question

Using the code below, I am getting divs with class 'post' from an external HTML file and print them to the posts page. Everything shown below works as it should be, however I would like to supplement the code with some automation. More precisely, instead of having hard coded values in the arrays I want to pass variable which were obtained by iterating through all divs with the needed class. Could you please help to implement such action. Thanks in advance.

PHP

<?php

$doc = new DOMDocument();
$doc->loadHTMLFile($url);

$xpath = new DOMXpath($doc);

$post = $xpath->query("//*[contains(@class, 'post')]");

$array = iterator_to_array($post);
?>

HTML posts page

<div><?php  echo $doc->saveHTML($array[0]);?></div>
<div><?php  echo $doc->saveHTML($array[1]);?></div>
<div><?php  echo $doc->saveHTML($array[2]);?></div>

HTML external file

<div class="post">
    post 1 
</div>      
<div class="post">
    post 2 
</div>      
<div class="post">
    post 3
</div>

Not sure if i understood your question .. is this what u wanted ?

foreach ($array as $key => $value)
 echo "<div> $value </div>";

OR

foreach ($array as $key => $value)
 echo "<div> ".$doc->saveHTML($value)." </div>";

Update

If you are looking for a function [Askd in comments]

function printdiv($value){
 echo "<div> ".$doc->saveHTML($value)." </div>";
}

then call it from wherever you want eg. via foreach loop

foreach ($array as $key => $value)
 printdiv($value);
