Hey, I need to delete all images from a string and I just can't find the right way to do it.
Here is what I tryed, but it doesn't work:
preg_replace("/<img[^>]+\>/i", "(image) ", $content);
echo $content;
Any ideas?

you can use txt2re.com to formulate regular expression. Usually, I use this one and after that, modify the code as per my need.FerdousTheWebCoder– FerdousTheWebCoder2019-02-04 09:03:57 +00:00Commented Feb 4, 2019 at 9:03

Try dropping the \ in front of the >.
Edit: I just tested your regex and it works fine. This is what I used:
<?
$content = "this is something with an <img src=\"test.png\"/> in it.";
$content = preg_replace("/<img[^>]+\>/i", "(image) ", $content);
echo $content;
?>
The result is:
this is something with an (image) in it.

Can you make this except of (image) it will replace with the alt of an image?

preg_replace("/<img[^>]+\>/i", "(image) ", $content); Hows that's different from the actual question?You need to assign the result back to $content as preg_replace does not modify the original string.
$content = preg_replace("/<img[^>]+\>/i", "(image) ", $content);

This strips all tags, not only img tags.
Sean it works fine i've just used this code
$content = preg_replace("/<img[^>]+\>/i", " ", $content);
echo $content;
//the result it's only the plain text. It works!!!

I wanted to display the first 300 words of a news story as a preview which unfortunately meant that if a story had an image within the first 300 words then it was displayed in the list of previews which really messed with my layout. I used the above code to hide all of the images from the string taken from my database and it works wonderfully!
$news = $row_latest_news ['content'];
$news = preg_replace("/<img[^>]+\>/i", "", $news);
if (strlen($news) > 300){
echo substr($news, 0, strpos($news,' ',300)).'...';
}
else {
echo $news;
}
$this->load->helper('security');
$h=mysql_real_escape_string(strip_image_tags($comment));
If user inputs
<img src="#">
In the database table just insert character this #
Works for me

simply use the form_validation class of codeigniter:
strip_image_tags($str).
$this->load->library('form_validation');
$this->form_validation->set_rules('nombre_campo', 'label', 'strip_image_tags');
