It's usually used as a single character wildcard. So "something = ?" would match
"A", "B", "1", etc.. but not "AB, "A1".

In the some code I'm working with I see many database queries using the
PEAR DB class where "?" is used for a value in the SQL. What is the
rule for using "?" in this way what value does it take.
Example code.
$ticket=$db->getRow(
"SELECT id,department,
from, cc, bcc FROM tickets WHERE
id=?",
array($tid)
);
