Questions tagged [php-5.4]

PHP 5.4 is the successor to PHP 5.3. It was released on March 1, 2012. Use this tag for version-specific issues relating to specifically to PHP 5.4.

PHP 5.4 Changes:

  • Support for traits has been added.
  • Short array syntax has been added, e.g. $a = [1, 2, 3, 4]; or $a = ['one' => 1, 'two' => 2, 'three' => 3, 'four' => 4];.
  • Function array dereferencing has been added, e.g. foo()[0].
  • Closures now support $this.
  • <?= is now always available, regardless of the short_open_tag php.ini option.
  • Class member access on instantiation has been added, e.g. (new Foo)->bar().
  • Class::{expr}() syntax is now supported.
  • Binary number format has been added, e.g. 0b001001101.
  • Improved parse error messages and improved incompatible arguments warnings.
  • The session extension can now track the upload progress of files.
  • Built-in development web server in CLI mode.

See Migrating from PHP 5.3.x to PHP 5.4.x for more information.
