PHP从URL获取数组

Question

I'm trying to make a PHP array from a URL string.

My code:

$files = urldecode($_POST['files']); // The String
error_log($files); // Output to see how it looks like
parse_str($files); // parse...
error_log($files[0]); // See the result

My Error_log after I run the script:

file[]=U07ttCL89
f

(If someone is wondering why I output with error_log - it because I can't see the output)

Why is it returning f after parsing?

The $_POST['files']] syntax is :

file[]=XXXXXXXXX&file[]=YYYYYYYY&file[]=ZZZZZZZZZ

Answer 1

You have a typo. The new var is file not files ;)

error_log($file[0]); // See the result

You can access a string like an array. If you use $files[0], you ouput the first char of the string, which is stored in $files. In your case it is file[]=XXXXXXXXX&file[]=YYYYYYYY&file[]=ZZZZZZZZZ

Answer 2

Use this:

$files = array();
$count = count($_POST['files']);
for($i=0;$i<$count;$i++){
  $files[] = $_POST['files'][$i];
}

UPDATE: The answer is actually simpler

$files = $_POST['files'];
