MySQL won't load on localhost - php

Question

I can't get mysql table to load on localhost. below i used PDO and the table worked fine. no errors...the table works fine in phpmyAdmin...please help driving me nuts. i imported table from my web server to local host from a earlier version..
<?php
$user = "root";
$pass = "root";
try {
$dbh = new PDO('mysql:host=localhost;dbname=iosLeads',$user,$pass);
foreach($dbh->query('SELECT * from Customer') as $row) {
print_r($row);
}
$dbh = null;
} catch (PDOException $e) {
print "Error! :" . $e->getMessage()."<br/>";
die();
}
?>
but when i used this code it show a blank screen, no errors..i tried same code with other tables and it works fine.
<?php
// set up the connection variables
$db_name = 'iosLeads';
$hostname = 'localhost';
$username = 'root';
$password = 'root';
// connect to the database
$dbh = new PDO("mysql:host=$hostname;dbname=$db_name", $username, $password);
// a query get all the records from the users table
$sql = 'SELECT * FROM Customer';
// use prepared statements, even if not strictly required is good practice
$stmt = $dbh->prepare( $sql );
// execute the query
$stmt->execute();
// fetch the results into an array
$result = $stmt->fetchAll( PDO::FETCH_ASSOC );
// convert to json
$json = json_encode( $result );
// echo the json string
echo $json;
?>
I'm getting this in my php error.log

Answer 1

If the array in $result has strings other than UTF-8 encoded, the function json_encode() may fail and will return false (see PHP manual json_encode). To check this, dump the value of $result before using json_encode():
var_dump($result);
If you have an array in $result but no other return value than false from json_encode(), you must set the correct character encoding for the database connection.
