Creating array in loop and getting result problem

[SUNIL16]

Hi friends,

 

below is my code

$arr1 = array('a'=>'1');
  $arr2 = array('a'=>'0.5');
  $arr3 = array('b'=>'1');
  $arr4 = array('a'=>'1.5');
  $arr5 = array('c'=>'1');
  $arr6 = array('b'=>'1');
  $arr7 = array('c'=>'1.5');
  $arr8 = array('a'=>'1');
  
  $all_array = array_merge_recursive($arr1, $arr2, $arr3, $arr4, $arr5, $arr6, $arr7, $arr8);
  echo "<pre>";
  print_r($all_array);
  echo "</pre>";
  
  foreach($all_array as $all_array_key => $all_array_value)
  {
      $all_count = 0;  
      foreach($all_array_value as $all_array_value_key => $all_array_value_value)
      {
          $all_count += $all_array_value_value;
      }
       
    echo $all_array_key." = ".$all_count."<br>";
  }
  

 

 

now result i am getting

a = 4

b = 2

c = 2.5

 

but my condition is not this i will be creating multiple array using loop, then how can use array_merge_recursive?

 

I want for this above result

 

for($i = 0; $i<$num ; $i++)

{

$arr.$i = array('a'=>'1');//like this i will be sending value dynamically

//(say second will be array('b'=>'1.5') 3rd array('c'=>'1'), 4th array('a'=>'1.5') like that

}

 

then it will create arrays untill that $num value reaches,

 

now how can i get the result in the same way as above.

 

Please let me know any logic or code. how to do this.

Please any one having any logic

Where are the indices, 'a','b','c', etc., coming from?

Hi kenrbnsn,

 

They are coming from database.

 

 

for($i = 0; $i<$num ; $i++)

{

$arr.$i = array('$result[type]'=>'$result[values]'); this will be 'a'=>'1'

}

 

 

[kenrbnsn]

Instead of doing "$arr.$i", which actually should be written as ${'arr'.$i}, you need to do something like

<?php
$arr = array();
for ($i = 0; $i < $num; ++$i) {
    if (!is_array($arr[$i])) {
         $arr[$i] = array();
    }
    if (!is_array($arr[$i][$result['type'])) {
        $arr[$i][$result['type']] = array();
    }
    $arr[$i][$result['type']][] = $result['value'];
}
?>

 

Note: untested.
