How do I get multiple images from a single string - php

Question

I've looked around and haven't found a answer that did it for me. I don't want all the images from an HTML page. I just want all the images from a single string.
On a page, I'm using two different strings. I want all the images that are within the second image. I want to loop them into a carousel.
I've looked around a bit and this is what I got:
function GetImgString($plaatje){
preg_match_all('/<img[^>]+>/i',$plaatje, $result);
$house = $result[0];
$i = 1;
$output = '<div class="carousel-inner">';
foreach ( $house as $houses ) {
if ($i == 1) {
$output.= '<div class="item active">';
}else{
$output.= '<div class="item">';
}
$output.=
$house.'
<div class="container">
<div class="carousel-caption">
</div>
</div>
</div>
';
$i++;
}
$output .= '</div>';
return $house;}
This is the output:
Array
(
[0] => &ltimg src="images/Huizen/huis-3.jpg" alt="" />
[1] => &ltimg src="images/Huizen/huis-4.jpg" alt="" />
)
How do I solve this?

Answer 1

I assume, when you do the regexp, in your results, there are the 2 images.
You are start to building your output into a variable, calles $output, but you return with $house, what contain the 2 result from preg_match.
So you can try with this:
function GetImgString($plaatje) {
preg_match_all('/<img[^>]+>/i', $plaatje, $result);
$houses = $result[0];
$houses = str_ireplace('<', '&lt', $house);
$houses = str_ireplace('>', '&gt', $house);
$i = 1;
$output = '<div class="carousel-inner">';
foreach ($houses as $house) {
$class = ' class="item"';
if ($i === 1) {
$class = ' class="item active"';
}
$output.= '<div '.$class.'>';
$output.= $house . '
<div class="container">
<div class="carousel-caption"></div>
</div>
</div>' . "\n";
$i++;
}
$output .= '</div>';
return $output;
}
