Uncover the grave of create_function().

Anonymous functions from this function were introduced in PHP4, obsolete with the introduction of closures in PHP5, and finally purged in PHP8.

Installation

composer require php5friends/polyfill-create_function

Security issue

This package uses eval to generate functions. The caller user of the function is responsible for not executing unexpected code.

In particular, generating a function using external input or a string stored in the Database poses a significant risk.

Functions

This package provides Php5Friends\create_function() and create_function()

Php5Friends\create_function()

Wrapper function of create_function(). Provides a function generation mechanism for environments where create_function() function does not exist.

Php5Friends\create_closure()

Create a Closure from same paremeters of create_function().

create_function() for PHP 8

Simply Polyfill function of create_function().
