How can PHP developers optimize code to accurately retrieve and utilize image dimensions in a web development project?

To accurately retrieve and utilize image dimensions in a web development project, PHP developers can use the getimagesize() function to obtain the width and height of an image. This function returns an array containing the dimensions as well as other information about the image, which can then be used in various ways within the project. 

// Get the image dimensions
$image_info = getimagesize('image.jpg');
$image_width = $image_info[0];
$image_height = $image_info[1];

// Output the dimensions
echo "Image width: " . $image_width . "px<br>";
echo "Image height: " . $image_height . "px";
