In this tutorial, we will learn how to get the image width and height in php. We will use getimagesize() function to implement it.

Here is an example.

<?php
$imgsize_arr = getimagesize('image/image_file.jpg');
$img_width = $imgsize_arr[0];
$img_height = $imgsize_arr[1];
echo "Image width: ".$img_width."<br/>Image height:".$img_height;
?>
