Description:

From manual page: http://www.php.net/function.in-array

In the "Description" section, the document states:
> Searches haystack for needle using loose comparison unless strict is set. 

As the function requires "needle" then "haystack", it would make sense to reword the statement to reflect the function's actual requirements.

e.g. change to:
> Searches with needle in haystack using loose comparison unless strict is set. 

It may seem pedantic, but the wording in the current sentence sincerely confused me and I was having errors with the function until I read examples and found the function required needle then haystack.

This change would also bring continuity to the in_array documentation and match the "Parameters" and "Examples" sections.

Kind Regards,
Greg
