I am unable to execute a code inside catch block when there is a file exception. Below is the code.

try 

 // Check for file size. which will make sure file exists in local server.
 filesize($localPath);
 return 'success';
 catch(FileException $e) 

 Log::error('Error reading file size ' . $e->getMessage());
 $failedAttempts = $failedAttempts + 1;

 // Set to sleep for 10.
 sleep(10);

 // Start recursive call.
 $this->downloadMedia($url, $localPath, $failedAttempts);
 

I also tried Exception and ErrorException but nothing worked. Any help is appreciated.

if You check this manual You'll see filesize method does not throw exception.

Returns the size of the file in bytes, or FALSE

(and generates an error of level E_WARNING) in case of an error.

and since looks like You've not enabled error reporting or display_error directive - You don't see that E_WARNING

You can just throw exception manually:

try 

 // Check for file existence or throw exception.
 if (!is_file($localPath)) 
 throw new Exception($localPath.' does not exists');
 
 return 'success';

catch(Exception $e) 

 // here goes exception handling

Extra advice (out of question's scope):

There is no logic to check for file existence in recurring way.

If file is downloaded it will exist otherwise You'll never download it during recursion.

What if someone will pass link to file that does not exists?

Better jus download it and stop with success or exception.
