Re: [PHP-DB] Database search question
Hmm to do a search on one table it might actually be quicker to do a query for every thing in the query. First convert to all lowercase. Then explode the query into an array using " " as the delimiter. Then implode this array into a list that looks something like this. "var1","var2"...) you can do this by using implode and putting Quotes at the end. Then in the query you can use the IN part of the query. I'm sorry if this is totally incorrect but I'm going off my memory. SELECT fields FROM tbl WHERE tblFields IN ($query) it might be INTO but I'm dang sure it is IN. Go to Zend.com and phpbuilder.com for some good resources on search engines you can modify it to suit your needs. I this helps a little bit. -Mike - Original Message - From: "Chris Payne" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Saturday, March 30, 2002 7:15 PM Subject: [PHP-DB] Database search question Hi there everyone, How can I accomplish the following?

RE: [PHP-DB] Database search question
Disclaimer: Its late, I'm tired and I haven't tested this code. Hope it
helps.
Quick Overview:
//make your dictionaries all lower case for ease
$countries = array( 1 => 'us', 2 => 'germany', 3 => 'australia' );
$cities = array( 1 => 'new york', 2 => 'berlin', 3 => 'sydney' );
$lodging = array( 1 => 'hotel', 2 => 'motel', 3 => 'inn', 3 => 'bed and
breakfast' );
$query = "hotel germany";
//user will put it in wrong case.
$query=strtolower($query);
//loop over each array and use it to figure out what column in table to
query
foreach ($countries as $country) {
if $country
if (strstr($query, $country)) {
$column = "country";
//need to break out of loop here
}
}
Hope it helps and isn't too wrong. I think you get the idea. Build up some
data dictionaries that map parts of the input to the columns and the
construct query dynamically. If you can't figure it out, generate a ui on
the fly asking "By X did you mean?" and then 3 radio buttons to set the
right column.

eregi() is for case-insensitive matching
The preg_* functions allow switching back and forth between case-sensitive
and case-insensitive subpattern matching within a single pattern.
