使用exiftool将图片中的元数据提取到json对象中

Question

I'm developing a website where I need to extract the metadata of an image (jpeg) with exiftool. I'm doing it with this code:

$cmd = exec("exiftool ".$this->url, $result);

$result is now a classic array:

array (size=113)
0 => string 'ExifTool Version Number         : 10.40' (length=39)
1 => string 'File Name                       : photo7.jpg' (length=44)
2 => string 'Directory                       : images' (length=40)
3 => string 'File Size                       : 139 kB' (length=40)
4 => string 'File Modification Date/Time     : 2017:11:26 16:27:05+01:00' (length=59)
5 => string 'File Access Date/Time           : 2017:12:17 23:07:18+01:00' (length=59)
6 => string 'File Inode Change Date/Time     : 2017:11:26 16:27:05+01:00' (length=59)
7 => string 'File Permissions                : rw-r--r--' (length=43)
8 => string 'File Type                       : JPEG' (length=38)
9 => string 'File Type Extension             : jpg' (length=37)
...

But I want to turn this array into an other array with meaningful keys and not numbers. Something even better would be to have a json object. In any case, I want the final array to looks like this:

    array (size=113)
'ExifTool Version Number' => string '10.40' (length=5)
'File Name' => string 'photo7.jpg' (length=10)
...

Is there a simple way to achieve this?

Answer 1

Just split the strings at the colon...

$result2 = array();
foreach($result as $value){
    $tmp = preg_split("#\s*\:\s*#", $value);
    $result2[$tmp[0]] = $tmp[1];
}
$result = result2;
