Deprecated features in PHP 5.3.x

PHP 5.3.0 introduces two new error levels: E_DEPRECATED and E_USER_DEPRECATED. The E_DEPRECATED error level is used to indicate that a function or feature has been deprecated. The E_USER_DEPRECATED level is intended for indicating deprecated features in user code, similarly to the E_USER_ERROR and E_USER_WARNING levels.

The following is a list of deprecated INI directives. Use of any of these INI directives will cause an E_DEPRECATED error to be thrown at startup.

Deprecated functions:

Deprecated features:

  • Assigning the return value of new by reference is now deprecated.
  • Call-time pass-by-reference is now deprecated.

A backward compatibility break which is not documented:

Fatal error: Uncaught exception 'RuntimeException' with message 'Directory name must not be empty.'

This happens with new RecursiveIteratorIterator( new RecursiveDirectoryIterator( $staticPath ) )

If you previously defined register_long_arrays in php.ini and have a lot of code with $HTTP_*_VARS that need to be replaced the following may help on *.nix systems:

sed -i 's/\$HTTP_\(.*\)_VARS/\$_\1/g' filename.php

What this command does is replace all occurrences of $HTTP_*_VARS with their respective $_ counter parts, e.g. $HTTP_COOKIES_VAR to $_COOKIES

To replace alot of files, you might combine it with the find command: 
find ./ -name "*.php" -exec sed -i 's/\$HTTP_\(.*\)_VARS/\$_\1/g' {} \;

For other deprecated variables like $HTTP_POST_FILES change your sed arguments:

sed -i 's/\$HTTP_POST_FILES/\$_FILES/g'

Deprecated variables created by the register_long_arrays directive as far as I know are:

Correction on my previous note.

sed -i 's/\$HTTP_\(.*\)_VARS/\$_\1/g' {} \;

will screw up multiple instances of $HTTP_*_VARS in the file.

You'll have to use an instance of sed like:

sed -i 's/\$HTTP_SERVER_VARS/\$_SERVER/g'
find ./ -name "*.php" -exec sed -i 's/\$HTTP_POST_VARS/\$_POST/g' {} \;
find ./ -name "*.php" -exec sed -i 's/\$HTTP_GET_VARS/\$_GET/g' {} \;

for each of the deprecated variables you might have in your files.

It also occurred to me a simple php conversion script would also work:


add directory recursion functions, ect.
