PHP Fatal error: Cannot redeclare

Modified on:
PHP Fatal error PHP Fatal erro redeclare php redeclare function redeclare function PHP Fatal error Cannot redeclare

If you see error message 'PHP Fatal error: Cannot redeclare function' or similar error message in your script, it means there is a problem with your script code (it tries to declare the same function multiple times).

This error says that your function is already defined. This could mean:

  • you have the same function defined in two files
  • you have the same function defined in two places in the same file
  •  the file in which your function is defined is included two times (so, it seems the function is defined two times)

To help with the third point, a solution would be to use include_once instead of include when including your functions.php file -- so it cannot be included more than once.
