How do I turn a variable into an array?

[horseatingweeds]

I'm having trouble understanding this of finding an example.

 

How do I make a variable like this:

 

$state = "\

US:AK:Alaska|\

US:AL:Alabama|\

US:AR:Arkansas|\

US:AS:American Samoa|\

US:AZ:Arizona|\

";

 

Into an array? I then want to cut each array value into its three parts so I can convert the state code to the actual name.

explode() with |\ as delimiter, then explode() with : delimiter

Right, I understand that. I'm confused how to get it into the arrays.

If you want state code => name, try this:

 

$state_arr = explode("|\n", $state); # if "|\n" is the delimineter
$lookup_tab = array();
foreach ($state_arr as $s) {
  list($country, $code, $name) = explode(':', $s);
  $lookup_tab[$code] = $name;
}
print_r($lookup_tab);

btherl, thanks.

 

I'm understanding better now.

How can I alter the above code to also include a numerical index? Like ($number, $country, $code, $name).

Not 100% sure what you want here.. but maybe something like this:

 

$state_arr = explode("|\n", $state); # if "|\n" is the delimineter
$lookup_tab = array();
$i = 0;
foreach ($state_arr as $s) {
  list($country, $code, $name) = explode(':', $s);
  print "$i, $country, $code, $name\n";
  $lookup_tab[$code] = $name;
  $i++;
}
print_r($lookup_tab);

 

I haven't actually stored the numerical index because I'm not sure where you want it.  But that code should demonstrate how to make it available.
