Data Structures

[Andrew Peskin]

Is it possible to create data structures in PHP and if so, would someone
provide a bried example?

Example:

I would like to create a Data Structure JRec which has the following fields

lID (Long)
dtDate (Date)
sName (10 Character String)

Thanks.

Re: Data Structures

Use objects, classes or arrays. See the PHP manual for more details.

Quick example:
<?php
$foo->lID = 10;
$foo->dtDate = date();
$foo->sName = "I like PHP";
?>

Thank you very much for your quick response ... another question ... if
you wanted to read/write data from/to a binary file, can you do this
from PHP?

I should add ... can you read/write to a binary file, whole objects, in
your example above, can you write $foo to a binary file, then read the
binary file and place the record into a new variable $foo1?

Yes. See http://php.net/serialize and fwrite/fread.
Also see http://php.net/download-docs.php
