Reading a large file from a remote server using a PHP script

Question

I am trying to read large files, say an illustrator file or a photoshop file, using cron on my system. File size varies from 20 to 300 mb

I use some kind of function, but during reading it breaks into the middle. Therefore, I wanted to get a new opinion.

Sum of these functions

• file_get_contents
• ReadFile
• curl

which is most effective in terms of

• Consistency (should not be interrupted when reading a file)
• speed
• uses a resource

if there are more than two cron jobs, does this affect all server performance.

Pass the code of best practice.

Thanks in advance
