PHP pattern match search system - php

Question

I am trying to have PHP search based on letters entered into a text box. I want it to match a pattern and find the relevant results from the database.
So if I typed in
"Jo Smi"
It would find results
Jo Smith, Pojo Smithson, Ojo Smith
How would one achieve this. I know how to get information from the database but not parts of various fields.
The objective is to search through users searching in fields user_firstname, user_lastname and user_email
Any ideas?

Answer 1

You should be able to do that directly from your query.
get the text box results and escape them then do
SELECT * FROM `database` WHERE `name` REGEXP '{INPUT TEXT HERE}';
That should work I think.

Answer 2

You can do simplistic searching on fields in a database using the LIKE clause:
$query = "SELECT Fields FROM Table WHERE TestField LIKE '%".$escapedTextString."%'";

Answer 3

Do a LIKE search against an upper-cased version of your search terms. Don't forget to mysql_real_escape_string().
$searchpattern = mysql_real_escape_string(strtoupper("Jo Smi"));
mysql_query("SELECT * FROM table WHERE UPPER(column) LIKE '%$searchpattern%';");

Hello Man previous answer is good
but you want to know this info
get the variable => $name =
$_GET['name'];
if you want to make it upper case
use strtoupper();
if you want to
make it Lower case use
strtolower();
if you want to
search you should replace = with
where like where name = $name to
where name like $name
this info
abc% => variable start with abc and finish with any thing
%abc% => variable start any thing , contain abc , finish with any thing
%abc => variable start any thing ,finish with abc
