how to know if an array is on the last positon - HTML Forums

DamianWarS · 10-21-2009, 07:46 AM

I have an array with string values as indices. I want to be able to loop through the array until it has reached the last index but I want to control when it goes to the next position and I don't want the loop to control it. So I want to use a while loop to check if the array has reached the last position or not. If it hasn't reached the last position I want it to continue the loop otherwise it ends the loop. I don't want to use a foreach loop or array_walk because I want to control the position of the array. Is there a way to check if the array's position is at the end? here is some pseudo code of what I want to accomplish:

PHP Code:


			
while (is array's position at the end?){

  if(condition) {

    next($array)

  }

}

im using current(array) as my check to see if the array has past the last postion or not. here is an example:

PHP Code:


			
$a = array("index1"=>32, "index2"=>30, "index3"=>34);

while(current($a)){ 

    echo key($a) . " = " . current($a) . "<br />"; 

    next($a);

}

the output should be:

Code:

index1 = 32
index2 = 30
index3 = 34

the php manual for current says:

Quote:

If the internal pointer points beyond the end of the elements list or the array is empty, current() returns FALSE

which works pretty well for what I want.
