Saleforce uses 15-character IDs as primary keys for every record. When
retrieving an ID over the API,
18-character case-insensitive IDs are returned. Generally, this doesn't cause
any problems because the 18-character version can be used anywhere the
15-character one is. One problem arises though when you are storing IDs in a
text field. In this case, you may need to convert a 15-character ID into its
18-character version. Salesforce provides a description of how
to perform this conversion.
Here is a PHP implementation of the algorithm.
function sf15to18($short) {
$chunks = str_split($short, 5);
$extra = '';
foreach ($chunks as $chunk) {
$chars = str_split($chunk, 1);
$bits = '';
foreach ($chars as $char) {
$bits .= (!is_numeric($char) && $char == strtoupper($char)) ? '1' : '0';
}
$map = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ012345';
$extra .= substr($map, base_convert(strrev($bits), 2, 10), 1);
}
return $short . $extra;
}
