Blank page when entering space in php search - php

Question

When adding a name with a space in the search bar the header and the footer remains however the body disappears.
I even added ini_set('display_errors', '1') and ini_set( 'default_charset', 'UTF-8' ); to check for errors however that didn't help.
Please note that the function works fine except when when entering any spaces
Here is the code:
<?php
//ini_set('display_errors', '1');
//ini_set( 'default_charset', 'UTF-8' );
session_start();
$title="Search";
include('includes/connection.php');
$url=parse_url($_SERVER['REQUEST_URI'],PHP_URL_PATH);
$url_array=explode("/",$url);
$name=end($url_array);
$uname = urldecode($name);
$position="absolute";
$sql ="SELECT userName , firstName, lastName,id
FROM users
WHERE userName LIKE ?
or firstName like ?
or lastName Like ?
or concat(firstName,' ',lastName) = ?";
$params=array("$uname","$uname","$uname","$uname");
$query= $dbh -> prepare($sql);
if($query-> execute($params)){
$results=$query->fetchAll(PDO::FETCH_OBJ);
if($query->rowCount() > 6) {
$position="inherit";
} else {
$position="absolute";
}
}
if (!$results) {
$mess = true;
// echo '<script type="text/javascript">alert("Hi");</script>';
}
//else {
//$mess = true;
//$query->errorInfo();
//}
include('includes/header.php');
//else
//{
// $mess = $query->errorInfo();
// echo '<script type="text/javascript">alert("'.$mess[2].'");</script>';
//}
?>

Answer 1

Like statement does not work like that. You should change your query in the proper format.
Replace:
$params=array("$uname","$uname","$uname","$uname");
With:
$params=array("%$uname%","%$uname%","%$uname%","%$uname%");

Answer 2

1. Add $uname=str_replace(" ", "% %", $uname); after $uname = urldecode($name); to wrap each space with %
2. Replace concat(firstName,' ',lastName) = ? With concat(firstName,' ',lastName) like ?
3. Follow Tahasin instructions, Replace $params=array("$uname","$uname","$uname","$uname"); with $params=array("%$uname%","%$uname%","%$uname%","%$uname%");

I solved the problem by adding the following line in the home page
search = search.replace(/\s/g,"-");
And in my search page, I added the following code
$name=str_replace('-',' ',$uname);
You people are great, thank you for helping me out
