Hi,

 

 

How to push into the array

 

0//Push

0 //Skip

0//skip

0//Skip

0//Skip

1// Push

1//Skip

1//Skip

1//Skip

0 //Push

1 //Push

1 //Skip

 

 

If any change from 0 to 1 then push else skip that row.

 

If next row has the same value then push into the array else skip that row.

try this

$array =  array();
$previous = null;
foreach($row as $current) {
  if($previous === null || ($previous == 0 && $current == 1) || ($previous == 1 && $current == 0) ) {
    array_push($array, $current); //or u can use simply $array[] = $current
}
}

That won't work, since you're never setting $previous.

 

Try something like:

<?php
$test = explode(',','1,1,1,0,0,0,1,1,0,0,1,1,0,0,0,1');
$prev = -1;
$new = array();
foreach ($test as $t) {
        if ($t != $prev) $new[] = $t;
        $prev = $t;
}
echo implode(',',$new);
?>
