Increment a value inside php foreach?

Question

Is it possible to increment a php variable inside a foreach? I know how to loop by declaring outside.

I'm looking for something like the syntax below

foreach ($some as $somekey=>$someval; $i++)
{

}

Solution 1

No, you will have to use

$i = 0;
foreach ($some as $somekey=>$someval) {
    //xyz
    $i++;
}

Solution 2

foreach ($some as $somekey=>$someval)
{
     $i++;


}

Solution 3

lazy way of doing is:

{
    $i=1;
    foreach( $rows as $row){
        $i+=1;
    }
}

,but you have to scope foreach for $i to dont exist after foreach or at last unset it

$i=1;
foreach( $rows as $row){
    $i+=1;
}
unset($i);

, but you should use for cycle for that as leopold wrote.

Solution 4

I know it is an old one here, but these are my thoughts to it.

$some = ['foo', 'bar'];

for($i = 0; $i < count($some); $i++){
 echo $some[$i];
}

-- Update --

$some = ['foo', 'bar'];
$someCounted = count($some);

for($i = 0; $i < $someCounted; $i++){
 echo $some[$i];
}

It would achieve, what you are looking for in first place.
Yet you'd have to increment your index $i.
So it would not save you any typing.

Solution 5

$dataArray = array();
$i = 0;
foreach($_POST as $key => $data) {
    if (!empty($data['features'])) {
        $dataArray[$i]['feature'] = $data['features'];
        $dataArray[$i]['top_id'] = $data['top_id'];
        $dataArray[$i]['pro_id'] = $data['pro_id'];
    }
    $i++;
}
