Why do we use a token concept in PHP?

Why do we use a token concept in PHP?

Question is not specific to PHP only, it is generic for Web development, language will not matter.

OPTIMIZE TABLE should be used if you have deleted a large part of a table or if you have made many changes to a table with variable-length rows (tables that have VARCHAR, VARBINARY, BLOB, or TEXT columns).

Deploy and Release your PHP Applications with Phing

Deploy and Release your PHP Applications with Phing

Phing is a PHP project build tool based on Apache Ant. A build system helps you to perform a group of actions using a single command.
