An even more effective way:

#!/usr/bin/php
<?
$string = "author:Jane Smith institution:university of Cambridge year:1976";
$match = preg_split("/ (?=\w+:)/", $string, -1, PREG_SPLIT_DELIM_CAPTURE)
foreach ($match as $m){
list ($field, $value) = split(":", $m);
$sql_query[] = "$field = '$value'";
}
print "select * from database.table where " . join(" and ", $sql_query);
?>
