modifying an array

Hello,

I have an array :

Array ( '2' => '27584.10', '3' => '1008.00', '6' => 11393.55, '7' => 888.12 )

which i need to modify to fill missing keys from 0 to 11 with zero
value. Like this :

Array ( '0' => '0', '1' => '0', '2' => '27584.10', '3' => 1008.00', '4' =>
'0', '5' => '0', '6' => '11393.55', '7' => '888.12', '8' => '0', '9' =>
'0', '10' => '0', '11' => '0' )

but I couldn't find an array function to fill the missing keys with a zero
value.

Thank you.

Maybe, you should try prepare own function, for example:

$array = array('2' => '27584.10', '3' => '1008.00', '6' => 11393.55,
'7' => 888.12);

for ($i=0; $i<12; $i++){
if (!array_key_exists($i)) $array[$i] = 0;
}

Hello Marcin,

Thank you !

I was indeed using your solution but didn't know how to fill the empty
value.

Instead of using : $array[$i] = 0;
I was fighting with function like array_map. I was searching for
complication, because I wanted to fill the empty values at the right key
place.
Putting the values at the end of the array was the solution.

Now I just have to ksort() the array.

Thank you for your help and pointed me to the right direction.

Regards.

try

$b = $a + array_fill(0, 12, 0);
ksort($b);
print_r($b);

I'm curious why you need this.

Hello,

your example with array_fill is exactly what I needed.

Thank you.

Hello....

In that case, you are using a statement that create an Associative
Array. This means that every key is an string. Maybe you must change
and define the id as integer without the ' ($array[1]=value).

Ok. Now, you can take some different way: create the array filled woth
zero, and later change the values. Check on the PHP manual the
information about array_fill() function.

(If you want to iterate an array, use: while(list($a,
$b)=each($array)), where you can verify every position in the $array,
$a is the key and $b is the value)
