PHP array_push错误为“ Unexcepted T_STRING”

Question

<?php

require 'init.php' ;
$sql = "select * from contacts  ;
$result = mysqli_query($con ,$sql);
$response = array();

while($row = mysqli_fetch_array($result))
{
    array_push($response,array("name"=>$row['name'],"email"=>$row['email']));
}

echo json_encode($response) ;
mysqli_close($con);

?>

他们的错误发生在最后3行...错误是“ unknownd T_STRING”
