php array

[subhomoy]

Hello everybody

 

I am facing some problem with array..

 

I have a na array like this

$arr = array(

  [0]=>1,

[1]=>10,

[2]=>166,

[7]=>12,

[15]=>1365,

[20]=>1253,

.

.

.

.

.

[31]=>40

);

What i want is that to show the whole array.

 

The keys consist of all the dates of a month..

 

If no specific dates exits then it will show 0 for that corresponding dates..

 

Like the above array does not contain keys [3]. [4], [5], ....

 

I awant to show them as zero...

 

Like this

$arr = array(

  [0]=>1,

[1]=>10,

[2]=>166,

[3]=>0,

[4]=>0,

[5]=>0,

[6]=>0,

[7]=>12,

[15]=>1365,

[20]=>1253,

.

.

.

.

.

[31]=>40

);

Any help will be greatly appreciated... Thank u in advance....

for ($I = 1; $I < $lastday; $I++)
   if (array_key_exists($I,$ar))
       echo "$I is $ar[$I] <br>";
   else
       echo "$I is 0<br>";

$arr = $arr + array_fill_keys(range(0, max(array_keys($arr))), 0);

ksort($arr);

Cronix - Not familiar with array_fill_keys() nor range() but after reading the manual I think there is a flaw in this.  Your range will produce a set of values ending with whatever is the highest EXISTING key in the array.  Then array_fill_keys assigns a 0 value to all of the indices in the range set.  What about the days that were not in the original array higher than the existing max day?

Yeah, I was just going by the example he posted. If he needs that he can just change max(array_keys($arr)) to the number of days in the given month. He also has a "0" day, not sure how that's possible if it's the days of the month.
