I'm looking for some PHP scripts that be able to search into the Database and retrieve all the records that matches the user input string in the search form.

Please advise.

The script I am posting is a fairly advanced search page using left joins on tables, but I think you can grasp what the script is doing. This search allows for 3 different types of search methods (either used separately or in combination), and allows the user to sort the search results as well. Additionally, this script has restricted access to the page, but you can eliminate that if it is not necessary. I have the results in a repeating row (limited to 50 records per page)This is something I have used, adapted, and built upon several times. If you need the search to be less advanced, you can adapt to your needs as well. Granted, you probably didn't need the whole page of code, but I thought it would be helpful as well.

<?php require_once('connections.php'); ?>
<?php
if (!isset($_SESSION)) {
  session_start();
}
$MM_authorizedUsers = "";
$MM_donotCheckaccess = "true";

// *** Restrict Access To Page: Grant or deny access to this page
function isAuthorized($strUsers, $strGroups, $UserName, $UserGroup) { 
  // For security, start by assuming the visitor is NOT authorized. 
  $isValid = False; 

  // When a visitor has logged into this site, the Session variable MM_Username set equal to their username. 
  // Therefore, we know that a user is NOT logged in if that Session variable is blank. 
  if (!empty($UserName)) { 
    // Besides being logged in, you may restrict access to only certain users based on an ID established when they login. 
    // Parse the strings into arrays. 
    $arrUsers = Explode(",", $strUsers); 
    $arrGroups = Explode(",", $strGroups); 
    if (in_array($UserName, $arrUsers)) { 
      $isValid = true; 
    } 
    // Or, you may restrict access to only certain users based on their username. 
    if (in_array($UserGroup, $arrGroups)) { 
      $isValid = true; 
    } 
    if (($strUsers == "") && true) { 
      $isValid = true;

try to alter this script for your use:

input page:

<p>Search:</p>
<form name="form1" action="post" action="process.php">
<input type="text" name="text1" value="">
<input type="submit" name="submit" value="Submit">
</form>

process.php

//put your db connection here(for example localhost)....
$host="localhost";
$db_user="user";
$db_password="password";
$database="db";
$dbh=mysql_connect ($host, $db_user, $db_password) or die ('I cannot connect to the database because: ' . mysql_error());
mysql_select_db ("$database");

//string to be searched from the input form...
$str=$_POST['text1'];

//query string...
$query="SELECT field1,field2 from table1
             WHERE field1='$str'";

/* field1,field2 are fields you want to display,
table1 is the table where you want to search the data... */

$result=mysql_query($query);
$num=mysql_num_rows($result);

//display results...
while ($i<$num)
{
$field1=mysql_result($result,$i,"field1");
$field2=mysql_result($result,$i,"field2");
echo $field1;
echo ",";
echo $field2;
echo "</br>";
$i++;
}

Basically that's it...
