9999 Posted September 27, 2006 Share Posted September 27, 2006 This script excepts a user input and searches for it in the $info field of my delimited text file database. If a user enters multiple words it will search for the occurance of each word. My question is what would I change in my script to make it search for exactly what was typed in? I want to allow my users to first search for exactly what they type in and if the are not happy with the number of results returned, I will give them the opportunity to do a "deep search" which is what I already have.[code]<?php$months = array ( 'January' => '01', 'February' => '02', 'March' => '03', 'April' => '04', 'May' => '05', 'June' => '06', 'July' => '07', 'August' => '08', 'September' => '09', 'October' => '10', 'November' => '11', 'December' => '12',);if($_REQUEST['usersearch'] == '1') // Display Keyword Search Results{# $file = file('data.txt'); $search = $_GET['search']; $file = file('data.txt'); $keys = preg_split('/[\s,]+/', preg_replace('/([^a-z0-9\s])/i', '', trim($search) ) ); if (sizeof($keys) > 5) { die("Please enter less keywords."); } else if (empty($keys[0])) { die("Please enter a valid keyword."); } $pattern = '/('. implode('|', $keys) .')/i'; $matches = array(); $matchcount = 0; foreach (array_values($file) AS $data) { list($month, $day, $year, $info) = explode('|', trim($data) ); if (preg_match($pattern, $info)) { $matches["$year {$months[$month]} $day"][] = preg_replace($pattern, '<span style="color:red;">$1</span>', $info); $matchcount++; } } if (sizeof($matches) > 0) { ksort($matches); $count = 0; printf('<center><b><p>%d match%s found.</p></b></center>', $matchcount, $matchcount == 1 ? NULL : 'es'); $months = array_flip($months); // flip array toconvert months back to names foreach ($matches AS $days => $event) { foreach ($event AS $result) { list($year, $month, $day ) = explode(' ', $days ); $month = $months[$month]; // convert back to month name $count++; echo '<b><font face="Times New Roman">' . $count .
