Question

I am trying to empty the content of a directory using glob() and foreach() using

$files = glob('/upload/'.$id.'/temp/*.JPEG'); 
    foreach($file as $files){
    unlink($file);}

But I just keep getting ‘Invalid argument supplied for foreach()’

Is this just a syntax error or can I not use unlink() in a foreach loop?

Also, just out of curiosity, will this code find all files in a directory?

$files = glob('/upload/'.$id.'/temp/*.*');

Answer 1

Invalid argument supplied for foreach() means the argument you passed is not an array. Here you passed $file. $file is not array. In fact it does not exists yet.

The format of foreach is,

foreach (array_expression as $value)
    statement
foreach (array_expression as $key => $value)
    statement

From your code the correct solution would be

foreach ($files as $file)
