array_key_exists() - El Forum - 03-31-2010

My simple code checks if the array contains "hits" column and if not, then creates it for the first time by assigning a value to this column.

However after assigning this value the function array_key_exists() still "tells" in the next loop circulation that the "hits" key doesn't exist. Could you look and comment please?

Code:
foreach($bets as $bet)

{

$hit = 0;

if($bet->homeGoals == $bet->homeScore && $bet->awayGoals == $bet->awayScore):

  $hit = 1;

endif;

if($hit == 1)

{

   if(array_key_exists('hits', $standings)):

     $standings[$bet->username]["hits"] += 1;

     echo '$hit=1, key_exists '.$bet->username.'<br/>';

   else:

     $standings[$bet->username]["hits"] = 1;

     echo '$hit=1, not key_exists '.$bet->username.'<br/>';

   endif;

}

else 

{    

   if(!array_key_exists("hits",$standings)):

     $standings[$bet->username]["hits"] = 0;

     echo '$hit=0, not key_exists '.$bet->username.'<br/>';

   endif;

}

}

The result of the code is:

Code:
$hit = 0, not key_exists jack

$hit = 1, not key_exists jack    <-- after this line the array_key_exists("hits",$standings) function should always return TRUE;

$hit = 0, not key_exists masta

$hit = 1, not key_exists skurwix

$hit = 0, not key_exists skurwix

$hit = 0, not key_exists zari

$hit = 0, not key_exists zari

$hit = 0, not key_exists masta

$hit = 0, not key_exists jack

$hit = 1, not key_exists masta

$hit = 0, not key_exists skurwix

$hit = 0, not key_exists zari

$hit = 0, not key_exists jack

$hit = 0, not key_exists skurwix

$hit = 1, not key_exists trolek

After the line I marked above the array_key_exists() function should not return FALSE anymore or maybe I misunderstood something?

Please comment guys.

Havent had a good look at your function yet, but have tried useing

Code:
print_r( $standings );

just before the if statement, so you can see exactly whats in that array.

When you call

Code:
if(array_key_exists('hits', $standings)):

try changing it to

Code:
if(array_key_exists('hits', $standings[$bet->username])):

Works perfectly!

Thanks Andrew.
