How can I get the last element of an array without changing its internal pointer?
What i'm doing is:
while(list($key, $value) = each($array)) {
//do stuff
if($condition) {
//Here I want to check if this is the last element of the array
prev($array);
}
}
so end($array) would mess things up.
Try this:
<?php
$array=array(1,2,3,4,5);
$totalelements = count($array);
$count=1;
while(list($key, $value) = each($array)) {
//do stuff
if($count == $totalelements){ //check here if it is last element
echo $value;
}
$count++;
}
?>
for($count=1;list($key, $value) = each($array));$count++)Warning: this accepted answer is outdated and now triggers the following error. The PHP manual for the end() specifically says that function's parameter is passed by reference because it is modified by the function. This means you must pass it a real variable and not a function returning an array because only actual variables may be passed by reference.
Notice: Only variables should be passed by reference
It's simple, you could use:
$lastElementKey = end(array_keys($array));
while(list($key, $value) = each($array)) {
//do stuff
if($key == $lastElementKey) {
//Here I want to check if this is the last element of the array
prev($array);
}
}
Why not just using something like:
$lastElement= end($array);
reset($array);
while(list($key, $value) = each($array)) {
//do stuff
}
// Do the extra stuff for the last element
$value is the last element.Something like this:
$array = array_reverse($array, true);
$l = each($array);
$lastKey = $l['key'];
$array = array_reverse($array, true);
while(list($key, $value) = each($array)) {
//do stuff
if($key == $lastKey) {
echo $key . ' ' . $value . PHP_EOL;
}
}
The problem here is that if the array is big one then it'll take some time to reverse it.
array_keys. Also, click the big orange question mark to get formatting help and instructions.end()changes the arrays internal pointer, and it's mentioned in the question that it isn't of any help.$count = count($array);and check using it.
