replace into foreach

[snowman2344]

I have the following code that works great except when the variable is blank. I need to replace any blank varibles with  

 

Is there a Guru that can help

 

 
$game_results = file("include/game_results.csv");
foreach ($game_results as $game_result) {
list($date, $h_a, $w_l_t, $us, $them, $vs_team) = explode(",", $game_result);
echo "<tr><td align='center'>$date</td>
                 <td align='center'>$h_a</td>
                 <td align='center'>$w_l_t</td>
 <td align='center'>$us</td>
 <td align='center'>$them</td>		  
  <td align='center'>$vs_team</td>  </tr>";
}

Try:

 

list($date, $h_a, $w_l_t, $us, $them, $vs_team) = array_map(
	create_function(
		'$x',
		'return empty($x) ? " " : $x;'
	),
	explode(",", $game_result)
);

Works good except when the value is 0. it replaces the 0 with  . Any way around this

 

Thanks for the quick responce

empty returns true for 0, so compare it against null instead.

 

list($date, $h_a, $w_l_t, $us, $them, $vs_team) = 'hi,ho,hl,0,hm,hn';
$arr = array_map(
	create_function(
		'$x',
		'return $x == null ? " " : $x;'
	),
	explode(",", $game_result)
);

i just read the manual on create_function. I think im missing the point, lemme ask if i got this right...

 

its a function where you input as a string what you want the function to do, with the variables that you also input?

 

if im right, i have to say: What the hell? why wouldnt you just write out what you want to do in plain code?

Anonymous functions aren't available until PHP 5.3.0, if you were writing that code for a system with PHP 5.3.0 or higher installed you might do it this way:

 

list($date, $h_a, $w_l_t, $us, $them, $vs_team) = array_map(
	function($x){
		return $x == null ? " " : $x;
	},
	explode(",", $game_result)
);
