Without checking the return value of "prepare" if "exec" is used then it will cause Fatal Error.
"PHP Fatal error: Call to a member function execute() on a non-object "
To avoid this error,need to check return value as following:
<?php
$db = new SQLite3('school.db');
if($stmt = $db->prepare('SELECT id,student_name FROM classTen '))
{
$result = $stmt->execute();
$names=array();
while($arr=$result->fetchArray(SQLITE3_ASSOC))
{
$names[$arr['id']]=$arr['student_name'];
}
}
?>
