check if image exists php

Question

I am in the middle of coding up a property portal. I am stuck on checking images. I know how to check if an image url is set. But the problem is detecting if there is actually a valid image at the url. example : http://property.images.themovechannel.com/cache/7217/6094437/img_main.jpg This image url exists but the image is has now been removed so it just displays blank in my propety search page. Is there a way of checking there is an image there at the url and then displaying a placeholder if it doesnt exist. something like ``` $imageURL = "http://property.images.themovechannel.com/cache/7217/6094437/img_main.jpg"; if (exists($imageURL)) { display image } else { display placeholder } ``` But all this does is check the url exists, which it does there is just no image there Thanks in advance

Accepted Answer

Use `getimagesize()` to ensure that the URL points to a valid image.

```
if (getimagesize($imageURL) !== false) {
    // display image
}
```
