Last Updated : 19 Feb, 2020

The read_exif_data() function is an inbuilt function in PHP which is used to read the EXIF headers from an image file and is an alternate for exif_read_data().

Syntax:

array read_exif_data( mixed $stream, string $sections,
                     bool $arrays, bool $thumbnail )

Parameters: This function accepts four parameters as mentioned above and described below:

$stream: It specifies the image file.
$sections (Optional): It specifies the comma separated list of sections.
$arrays (Optional): It specifies whether not to present each section as array.
$thumbnail (Optional): It specifies whether to read thumbnail or not.

Return Value: This function returns an associative array on success or FALSE on failure.

Below examples illustrate the read_exif_data() function in PHP:

Example 1:

<?php 
  
// Open a the file from local folder 
$fp = fopen('./geeksforgeeks.jpg', 'rb'); 
  
// Read the exif headers 
$headers = read_exif_data($fp); 
  
// Print the headers 
echo 'EXIF Headers:' . '<br>'; 
  
print("<pre>".print_r($headers, true)."</pre>"); 
?> 

Output:

EXIF Headers:
Array
(
    [FileName] => geeksforgeeks.jpg
    [FileDateTime] => 1580889002
    [FileSize] => 17763
    [FileType] => 2
    [MimeType] => image/jpeg
    [SectionsFound] => 
    [COMPUTED] => Array
        (
             => width="667" height="184"
            [Height] => 184
            [Width] => 667
            [IsColor] => 1
        )

)

// Add comment to the image   
$image->commentImage("THIS IS MY COMMENT");  
  
// Save the file to local image 
$image->writeImage('geeksforgeeks.jpg'); 
  
// Open a the same file 
$fp = fopen('./geeksforgeeks.jpg', 'rb'); 
  
// Read the exif headers 
$headers = read_exif_data($fp, 'COMMENT', true, true); 
  
// Print the headers 
echo 'EXIF Headers:' . '<br>';
