foreach problem?

[ok]

Hi guys, very basic problem with foreach..

 

 

below is the codes.

  $multi_winner[$i] = $row['invited_by'];

  foreach ($multi_winner as $value2) {
echo "<br>multipler_winner: ". $value2;
  }

 

below is the error message.

Warning: Invalid argument supplied for foreach()

 

Thank you!

Try this

 

<?php
     $i=0;
     $multi_winner[$i] = 'test';

  foreach ($multi_winner as $value2) {
echo "<br>multipler_winner: ". $value2;
  }
?>

What I do to catch errors with foreach loops, is checking if the variable is actually an array. So like this:

 

<?php

$multi_winner[ $i ] = $row[ "invited_by" ];

if( is_array( $multi_winner )
{
      foreach( $multi_winner as $value )
      {
            print( "stuff" );
       }
}
?>
