Suppose I don't have access to a database server.
I have any indexed array of like keyed arrays, essentially mimicing a database table. Are there any libraries or functions that I can use to 'query' the array in a SQL like manner ?
e.g. $data = array (array(a=>1,b=>2,c=>3) ,array(a=>2,b=>3,c=>4) ,array(a=>3,b=>4,c=>5) );
I think foreach is about the only thing you can do here. If your issue is memory storage then you might consider using SQLite, never used it myself but I hear it's quite small and pretty fast.
Well I did think of one other possibility... if you really don't have a database option then you might structure your data into an xml file and then use XPath (I think PHP 5 only) to do queries like that. But a database would be better suited for this task.
