Split text file into equal blocks. How???

[josel]

I would like to limit size of content per page. So, given document (A), how can I load this document a block at a time? Better yet, how can I split the document into variables each holding X-bites?

Thank you all in advance!

Regards,


Jose Lerebours

Have you tried file()

array file ( string $filename [, int $flags [, resource $context]] )

Reads an entire file into an array.
Returns the file in an array. Each element of the array corresponds to a line in the file, with the newline still attached. Upon failure, file() returns FALSE.

or maybe

fread()

Description
string fread ( resource $handle, int $length )

fread() reads up to length bytes from the file pointer referenced by handle. Reading stops when up to length bytes have been read, EOF (end of file) is reached, (for network streams) when a packet becomes available, or (after opening userspace stream) when 8192 bytes have been read whichever comes first.

OK - This is a start. I guess the question now is how do I now how many elements are there in an array ???

Once I have a file read onto an array, array can then be referenced 0-X; X being the unknown ...

This is very good information vacunita (Do you know that vacunita in Spanish means "little vaccination"? - lol You could just be the vaccination I need to improve my PHP)

vacunita,

I found that the function sizeof() is the answer to my follow-up question.

Armed with this information, I can now write UDF that will accept three parameters ArrayName, StartRow, NumberOfRows

Using a for/next (or while) loop, I can set my pointer to StartRow and take it from there.

Once the loop is complete, I will then return the built string and ... I shall be victorious!

What do you think?

Thanks,

Jose Lerebours

You could also have used the count() function on the array, and gotten the number of entries in the array, then you would know how many lines there are, and decide how many to show.

By the way, the php.net online manual is your friend in these situations.
