for loop and array in PHP: add element only at last interation

Question

I have an empty array ($report), and i want to create a multidimensional array with element of "$array" The problem is that adds elements only for index = 2 (last interation). Why?

<?php
 $array= array("3,4","5,6","7,8");
 $report= array();
 for($i=0, $n= count($array); $i< $n; $i++){
      $lat= substr($array[$i],0,1);
      $lng= substr($array[$i],2,1);  
      $report= array(array($lat,$lng));
  }
  echo "<pre>";  print_r($report);

   ?>

You rewrite the array, to add item use $report[]= array(array($lat,$lng)); — splash58

In the line $report= array(array($lat,$lng)); you reinit array every pass of the loop. To add new item to array rewrite it to

$report[]= array(array($lat,$lng));

You are replacing the value of $report every iteration. Use this syntax to append to the array:

$report[] = array(array($lat,$lng));

The [] appends values to the end of an array.
