I am getting this error message while reading from a text file. Data is save correctly but there is error while reading.

 

Array ( [0] => Array ( [0] => ) [1] => Array ( [0] => ) [2] => Array ( [0] => ) [3] => Array ( [0] => ) )

Warning: Invalid argument supplied for foreach() in C:\wamp\www\earth\index.php on line 63

 

<?php function array2string($myarray,&$output,&$parentkey){
      foreach($myarray as $key=>$value){
         if (is_array($value)) {
            $parentkey .= $key."^";
            array2string($value,$output,$parentkey);
            $parentkey = "";
         }
         else {
            $output .= $parentkey.$key."^".$value."\n";
         }
      }
   }


   function string2array($string,&$myarray){
      $lines = explode("\n",$string);
      foreach ($lines as $value){
         $items = explode("&#38;#183;",$value);
         if (sizeof($items) == 2){
            $myarray[$items[0]] = $items[1];
         }
         else if (sizeof($items) == 3){
            $myarray[$items[0]][$items[1]] = $items[2];
         }
      }
   }


if(isset($_POST['save_value']) && ($_POST['save_value']==7) ) {

$index_name = $_POST['index_name'];
$curr_point = $_POST['current_pt'];
$point_change = $_POST['points_change'];
$per_change = $_POST['per_change'];

$mydb = array($index_name, $curr_point, $point_change, $per_change);
print_r($mydb);
// Convert the array into string
   	array2string($mydb,$output,$parent);

// Store the string in a file   
   	$f1 = fopen("test.txt","w+");
   	fwrite($f1,$output);
   	fclose($f1);
}

if(isset($_POST['show_records'])) {

// Read the file back from the disk
   $f1 = fopen("test.txt","r");
   $newString = fread($f1,filesize('test.txt'));
   fclose($f1);
   
   // Convert the content back to an array
   string2array($newString, $newArray);

   // Print out the array
   foreach ($newArray as $item) {   // this is line 63 
      print_r($item);
   }
}
?>

 

Any help much appreciated.

try to change function to

   function string2array($string,&$myarray){
      $lines = explode("\n",$string);
      foreach ($lines as $value){
         $items = explode("·",$value);
         if (sizeof($items) == 2){
            $myarray[$items[0]] = $items[1];
         }
         else if (sizeof($items) == 3){
            $myarray[$items[0]][$items[1]] = $items[2];
         } else echo 'error in string2array function';
      }
   }
