Resources are commonly used to iterate through a mysql or file handle.
example
<?php
while($row = mysql_fetch_row($resource)){
echo $row[0] ;
}
?>
It's possible to fake this treatment.
<?php
class fakewhile{
public $arrayCount;
public $arrayCounter;
function setArrValues(){
$this->arrValues = array(0
=>array("apple","artichoke","apricot"),1 =>
array("bears","dogs","cats"));
$this->arrayCounter = 0;
$this->arrayCount = count($this->arrValues);
}
function outputValues(){
/*
* Anything until the if statement is evaluted one more
* time then the array count value
*/
$arrayInfo = $this->arrValues;
$arrCounter = $this->arrayCounter;
if($arrCounter > $this->arrayCount){
return false;
}
$endCounter = $arrCounter+1;
$this->arrayCounter = $endCounter;
return $arrayInfo[$arrCounter];
}
}
$fw = new fakewhile();
$fw->setArrValues();
while($row = $fw->outputValues()){
print_r($row);
}
?>
Hopefully will get someone started on completing a complete application.
