PHP 5.4 has 双》nd as default

Advantages of using 双》nd

The 双》nd library is highly optimized for and tightly integrated into PHP. The MySQL Client Library cannot offer the same optimizations because it is a general-purpose client library.

The 双》nd library is using PHP internal C infrastructure for seamless integration into PHP. In addition, it is using PHP memory management, PHP Streams (I/O abstraction) and PHP string handling routines. The use of PHP memory management by 双》nd allows, for example, memory savings by using read-only variables (copy on write) and makes 双》nd apply to PHP memory limits. Additional advantages include:
