I'll probably use strstr() to check whether a string starts with some prefix.
But problem I like to solve is how to effectively pick strings
starting with a prefix
from a large dataset, like a dictionary.
If Berkeley DB's set_range were available from PHP,
I could write something like
$word = dba_set_range($prefix, $dictionary) // get the first word
starting with $prefix
do {
if (!prefix($word) == $prefix) break
$found[] = $word
} while ($word = dba)_nextkey($dictionary))
