The list is limited to a very specific set of functions that PHP is an ill fit to utilise and I have never seen used in a positive context. These are best done with a non-scripted program or perhaps Python.

Of course, no matter the language used, input sanitising is essential.

Edit: Since you've edited your post to add cURL to your criticism, please note I originally replied "These are best done with a non-scripted program or perhaps Python" for exactly this reason.

Much of the criticism of PHP can be leveled against its misuse as much as the language's own shortcomings.
