To read a TIFF file in PHP, you can use the Imagick extension which is a native PHP extension for reading and writing images in different formats, including TIFF. Here is a simple example of how to read a TIFF file using the Imagick extension in PHP:

// Path to the TIFF file
$tiffFile = 'path/to/your/file.tif';

// Create a new Imagick object
$image = new Imagick($tiffFile);

// Get the number of pages in the TIFF file
$numPages = $image->getNumberImages();

// Loop through each page in the TIFF file
for ($i = 0; $i < $numPages; $i++) {
    // Set the page number
    $image->setIteratorIndex($i);
    
    // Get the image data for the current page
    $imageData = $image->getImageBlob();
    
    // Do something with the image data (e.g. display it, save it to a file, etc.)
    // For example, you can output the image data as base64 encoded image:
    echo '<img src="data:image/tiff;base64,' . base64_encode($imageData) . '"/>';
}

// Destroy the Imagick object
$image->clear();
$image->destroy();


In this example, we first create an Imagick object with the path to the TIFF file. We then get the number of pages in the TIFF file using the getNumberImages() method. We loop through each page in the TIFF file and get the image data for that page using the getImageBlob() method. Finally, we can do something with the image data, such as displaying it on a webpage or saving it to a file.


Make sure you have the Imagick extension installed on your server in order to use this code. You can install it using the following command:

1
sudo apt-get install php-imagick


or

1
sudo yum install php-imagick


depending on your system's package manager.
