php arrays

[DazlerD]

Hi

 

Our servers have just been updated to php version 5.2.6 and we have started to get errors.

 

I have some code that initialises a two dimensional array with dates and hours.  We then fill the array and use this to display the info.

 

Here is my code to initialise the array.

 

// Setup Date Array.  Start of week is 03082008
for ($wd = 0; $wd < 7; $wd++)
{
  $col_name = date('dmY', mktime(0, 0, 0, date("m",$StartOfWeek)  , date("d",$StartOfWeek)+$wd, date("Y",$StartOfWeek)));
  $a_diary = array($col_name => array("00" => ".", "01" => ".", "02" => ".", "03" => ".", "04" => ".", "05" => ".", "06" => ".", "07" => ".", "08" => ".", "09" => ".", "10" => ".", "11" => ".", "12" => ".", "13" => ".", "14" => ".", "15" => ".", "16" => ".", "17" => ".", "18" => ".", "19" => ".", "20" => ".", "21" => ".", "22" => ".", "23" => "."));


  echo '<br>col_name = '.$col_name;
  echo '<br>$a_diary['.$col_name.']["15"] = '.$a_diary[$col_name]["15"];
}

  echo '<br>Show diary array for the week';
  echo '<br>$a_diary["03082008"]["15"] = '.$a_diary["03082008"]["15"];
  echo '<br>$a_diary["04082008"]["15"] = '.$a_diary["04082008"]["15"];
  echo '<br>$a_diary["05082008"]["15"] = '.$a_diary["05082008"]["15"];
  echo '<br>$a_diary["06082008"]["15"] = '.$a_diary["06082008"]["15"];
  echo '<br>$a_diary["07082008"]["15"] = '.$a_diary["07082008"]["15"];
  echo '<br>$a_diary["08082008"]["15"] = '.$a_diary["08082008"]["15"];

 

And here is the output:

 

col_name = 03082008
$a_diary[03082008]["15"] = .
col_name = 04082008
$a_diary[04082008]["15"] = .
col_name = 05082008
$a_diary[05082008]["15"] = .
col_name = 06082008
$a_diary[06082008]["15"] = .
col_name = 07082008
$a_diary[07082008]["15"] = .
col_name = 08082008
$a_diary[08082008]["15"] = .
col_name = 09082008
$a_diary[09082008]["15"] = .

Show diary array for the week
Notice: Undefined index: 03082008 in \\nas76ent\domains\p\mydomain.co.uk\user\htdocs\folder\date.php on line 226
$a_diary["03082008"]["15"] = 

etc etc

 

Is there any reason why the array can be interigated whilst in the for loop but outside the for loop it doesnt find the element?

 

Please help, this is messing with my mind !!  lol

 

Thanks

what you are doing is overriding the value

 

$a_diary each time....

 

you may try this:

 

// Setup Date Array.  Start of week is 03082008
for ($wd = 0; $wd < 7; $wd++)
{
  $col_name = date('dmY', mktime(0, 0, 0, date("m",$StartOfWeek)  , date("d",$StartOfWeek)+$wd, date("Y",$StartOfWeek)));
  $a_diary[$col_name] = array("00" => ".", "01" => ".", "02" => ".", "03" => ".", "04" => ".", "05" => ".", "06" => ".", "07" => ".", "08" => ".", "09" => ".", "10" => ".", "11" => ".", "12" => ".", "13" => ".", "14" => ".", "15" => ".", "16" => ".", "17" => ".", "18" => ".", "19" => ".", "20" => ".", "21" => ".", "22" => ".", "23" => ".");


  echo '<br>col_name = '.$col_name;
  echo '<br>$a_diary['.$col_name.']["15"] = '.$a_diary[$col_name]["15"];
}

  echo '<br>Show diary array for the week';
  echo '<br>$a_diary["03082008"]["15"] = '.$a_diary["03082008"]["15"];
  echo '<br>$a_diary["04082008"]["15"] = '.$a_diary["04082008"]["15"];
  echo '<br>$a_diary["05082008"]["15"] = '.$a_diary["05082008"]["15"];
  echo '<br>$a_diary["06082008"]["15"] = '.$a_diary["06082008"]["15"];
  echo '<br>$a_diary["07082008"]["15"] = '.$a_diary["07082008"]["15"];
  echo '<br>$a_diary["08082008"]["15"] = '.$a_diary["08082008"]["15"];
