I have an array of objects, any array in php. How do i skip the last element in the foreach iteration?
5 Answers
Use a variable to track how many elements have been iterated so far and cut the loop when it reaches the end:
$count = count($array);
foreach ($array as $key => $val) {
if (--$count <= 0) {
break;
}
echo "$key = $val\n";
}
If you don't care about memory, you can iterate over a shortened copy of the array:
foreach (array_slice($array, 0, count($array) - 1) as $key => $val) {
echo "$key = $val\n";
}

i don't know why it felt like it was a bad question, but this was certainly what i was asking about. I want to loop through everything but exclude the last element in the array.. Thanks

@muffin The question is really why that last element should be excluded in the first place ... if there's something special about that value, perhaps it shouldn't be there.

Both approaches worked fine, no errors... very self explanatory. Thank You.

array_slice( $array, 0, -1 );There's various ways to do this.
If your array is a sequentially zero-indexed array, you could do:
for( $i = 0, $ilen = count( $array ) - 1; $i < $ilen; $i++ )
{
$value = $array[ $i ];
/* do something with $value */
}
If your array is an associative array, or otherwise not sequentially zero-indexed, you could do:
$i = 0;
$ilen = count( $array );
foreach( $array as $key => $value )
{
if( ++$i == $ilen ) break;
/* do something with $value */
}

This is also a good answer ..upvote thanks :)

@muffin You're welcome. As you can see from other answers, there are lots of ways to achieve what you were after.

You have a typo in for-loop. Should be a semicolon instead of a comma.

@erfan It's not a typo. I'm initializing two variables (separated by a comma) in the first part of the for loop. Each expression in
for( expr1; expr2; expr3 ) can be empty or contain multiple expressions separated by commas.Irfanullah Jan
@DecentDabbler Oh wow ... I feel dumb now XD
If you don't want to delete the last array entry with pop, you could skip it like this
$array = array('v1','v2','v3',...)
$counter = 1;
foreach($array as $value)
{
//do your thing in loop
if($counter == count($array)) continue; // this will skip to next iteration if last element encountered.
$counter++;
}

What you are trying to do will defeat the purpose of foreach loop. It is meant to loop through the entire array and make our job easy.
for ex: You can get the array size using COUNT function in php and then can use for loop and set the limit to arraysize-2, so the last array will be omitted

$count = count($array);
$i=0;
foreach ($arr as &$value)
{
$i++;
if($i==($count-1))
{
echo 'skip';
}
else
{
echo $value;
}
}

Doesn't work if keys are strings.

@jack okk than I am editing my answer.. :)
ReNiSh AR
simply do this: for($i=0;$i<$count-1;$i++)
if $element == end($myarray) breakendonarray_keys.
