Best Of PHP Deprecations

4 real

• mbstring.func_overload

  This implies that code using mbstring.func_overload is incompatible with practically all other code, which is written under the assumption that basic string operations work normally.

• each()

  The each() function is inferior to foreach in pretty much every imaginable way, including being more than 10 times slower.

• assert() with string argument

  Using assert($value) to check if a value is truthy opens an RCE vulnerability if there is any chance for $value to be a string.

  ¯\_(ツ)_/¯

• $errcontext argument of error handler

  Due to technical issues, this does not throw a deprecation warning. It is a documentation-only deprecation.

• Reflection export() methods

  As such, the export() method is wholly unnecessary, confusing, and violates PHP's own inheritance rules.
