When the PHP code in the php-Web page writes data to the SQLite database, the string "000...0" is stored as 0, solving the reason?

Phpsqlite

Title, I used PHP to write data to a table in SQLite, containing the user name and password two fields, but when the field value (user name or password) is similar to "000...0" such as the value, the database saved in the field value is only one bit 0.
The PHP code is as follows

   
   open('survey.db');    }}$db = new MyDB();if(!$db){    echo $db->lastErrorMsg();} else {    echo "Opened database successfully\n";}$sql =<<
   
   
    
    exec($sql);if(!$ret){    echo $db->lastErrorMsg();} else {    echo "Records created successfully";}$db->close();?>
