How to remove first image from string - php

Question

I have the results from a database that contains images and text. I would like to remove the first image.
Example:
$string = 'This is some text and images
<img src="http://linktoimage" border="0">,
more text and <img src="http://linktoanotherimage"> and so on';
I would like to remove the first image, it is not always the same url.
Thanks for any help.

Answer 1

$string = 'This is some text and images
<img src="http://linktoimage" border="0">,
more text and <img src="http://linktoanotherimage"> and so on';
print preg_replace('/<img(.*)>/i','',$string,1);
The above should return
This is some text and images
,
more text and <img src="http://linktoanotherimage"> and so on
Assuming you know it'll be prefixed by spaces and a line break, and suffixed by a comma and line break (and you want to remove these, too), you can do
print preg_replace("/\n <img(.*)>\,\n /i",'',$string,1);
Which will give you
This is some text and images more text and <img src="http://linktoanotherimage"> and so on

Answer 2

There was a great answer on another Thread
function get_first_image($html){
require_once('SimpleHTML.class.php')
$post_dom = str_get_dom($html);
$first_img = $post_dom->find('img', 0);
if($first_img !== null) {
return $first_img->src;
}
return null;
}
You can do it via Regex expressions however regex isn't really suited for this.

Answer 3

$var = 'This is some text and images
<img src="http://linktoimage" border="0">,
more text and <img src="http://linktoanotherimage"> and so on';
echo preg_replace('/<img.*?>/', '123', $var, 1);
This should do it. ? in the regex is to make it ungreedy.

Answer 4

Being a RegEx newbie, I tend to avoid it and use something like:
$i = strpos($string,'<img');
if ($i !== false) {
$j = strpos($string, '>', $i);
if ($j !== false) $string = substr($string,0,$i) . substr($string,$j);
}
Probably should be $i-1 and/or $j+1 - I never remember exactly what it should be.

Answer 5

Finally nailed it down:
preg_replace('/<img[\S\s]*?>/i','',$txt,1)
This one also works for cases when you might have:
$string = 'This is some text and images
<img
src="http://linktoimage" border="0">,
more text and <img src="http://linktoanotherimage"> and so on';
(a new line character in the tag.)

Answer 6

This code works for me
$html is your html content variable from which you want to remove first image tag.
$str = preg_replace('/(<img[^>]+>)/i','',$html,1);
