i want to add value $b into array. array_push($new_array, $b); am i right?
Define the array.
Push the data into the array.
Example:
$array = new array();
foreach ($group as $b) {
if ($b == 0) {
echo "error";
} else {
echo "true";
array_push($array,$b) //or any value?
}
}

Use it:
array_push($arr,"true");
or
echo "true";
$arr[] = $b;

Use
$arr[] instead of array_push() - it's faster.use array_push check this link
$a = new array();
array_push($a,"true");
print_r($a);
We can add to a numerical array in these ways:
$arr = new array("true"); //Create the array & add the values
var_dump($arr); //Print the contents of the array to screen
You can also push values to an array:
$arr = new array(); //Create the array
array_push($arr, 'true'); //'Push' the value into the next available index
var_dump($arr); //Print the contents of the array to screen
You can also add to array by directly setting the index:
$arr = new array(); //Create the array
$arr[0] = 'true'; //'Set' index 0 to the value
var_dump($arr); //Print the contents of the array to screen
foreach
