Note:

• Implode () can, for historical reasons, accept the IT parameters in either order. For consistency with explode (), however, it may is less confusing to use the documented order of arguments.
• For historical reasons, implode () can receive two parameter sequences, but explode () does not work. However, you can avoid confusion by order in the document.

Pieces

• The array you want to convert.

Return Values
