Jimbo_17 Posted June 22, 2006 Share Posted June 22, 2006 I am trying to return an array, but only one element at a time. Much in the same way that mysql_fetch_array does. Here is an example of what I am trying to do.[code]class test { public function one(){ $test = array(1,2,3,4,5); foreach($test as $array){ return $array; } }};$TEST = new test();while($blah = $TEST->one()){ print $blah; //Want this to print out only one element at a time}[/code]Thanks in advance!

Buyocat Posted June 22, 2006 Share Posted June 22, 2006 When you say return, could you be more specific? Because the return command in a method can only be called once, as the method is exited as soon as something is returned. So if you want to interate through an array or something one at at time, returning a value each time. You'll either want to create a special iterator class that can remember its place in the array, or you'll just want a simple foreach loop that goes through the array one at a time letting you do stuff.EDIT - after looking at your example you want to create an interatorI'll let you devise an iterator class, it would need an attribute like $myPlace and would probably want some methods like, hasNext, next etc. Then you would call the method and next and it would return the next value in the array or whatever and increment the $myPlace value.

Jimbo_17 Posted June 22, 2006 Author Share Posted June 22, 2006 Thank you for the quick reply! I am trying to write a class that can treat a comma seperated values file (CSV) like a database. The problem I am running into is I want to have a function iterate through the file and grab the fields from one line at a time and spit them out. I need a way to grab the fields from one line, store them outside the class, and then go get the next line and start it all over.CSV Example:NAME,PHONE,ADDRESSBob,555-5555,32 Foo StreetShirley,555-5555,RM 354 Barr AptsI want the function to grab Bob's info, split it into an array, and then pass the array out of the class. Once the array is out of the class (In other words, in my index.php), I want it to get Shirley's info and do the same thing. Quote Link to comment Share on other sites More sharing options...
kenrbnsn Posted June 23, 2006 Share Posted June 23, 2006 You might want to take a look at the function [a href=\"http://www.php.net/fgetcsv\" target=\"_blank\"]fgetcsv()[/a].Ken Quote Link to comment Share on other sites More sharing options...
