Description:
------------
There is no documentation page available for array & string functions in chm 
format of PHP documentation. 

When I click on the link "array functions" on the array page it leads me back to 
the array page.

Also when I search for "array functions", "string functions" or "explode"(any of 
the array or string functions) in the index tab on left side, it shows me no 
search results.
