Cannot redeclare conenect() error using PDO - php

Question

I´m using pdo for my sql statements.
I have a connect.php file with this code:
<?php
function connect()
{
$dbHost = 'localhost';
$dbUser = 'root';
$dbPass = '';
$dbName = 'mysite';
try
{
$pdo = new PDO("mysql:dbname={$dbName};host={$dbHost}", $dbUser, $dbPass);
}
catch(PDOException $e)
{
echo $e->getMessage();
}
return $pdo;
}
?>
Now Im trying to use my connect.php in other php file like this:
include('../crud/config.php');
$pdo = connect();
And Im having this error:
Fatal error: Cannot redeclare connect() (previously declared in F:\Xampp\htdocs\projet\crud\config.php:9) in F:\Xampp\htdocs\projet\crud\config.php on line 32
Somebody there have some ideia why this is happening?
Maybe its because im using the statement like this with $pdo->
$verifyLevel = $pdo->prepare("SELECT * FROM administradores where id = :user");
$verifyLevel->bindValue(":user", $user);
$verifyLevel->execute();
$num_rows = $verifyLevel->rowCount();
$result = $verifyLevel->fetch(PDO::FETCH_ASSOC);
Because if I remove the $pdo = connect(); dont gives thar error but then gives other error but then because Im using $pdo->prepare to my sql statement I have an error because $pdo is not recognized without $pdo = connect()
