无法使用MAMP和PHP访问SQLite数据库

Question

I have been learning how to program websites lately and the time has come for me to add a database. I have in fact already successfully created a MySQL database and interacted with it with PHP.

My problem is I can't seem to access a SQLite database file with it. I am using MAMP to host locally for now. Here is a snippet of the code I am using to access the db and find and print out a value stored on it.

<?php
        $dbhandle = sqlite_open('/Applications/MAMP/db/sqlite/Users');

        if ($dbhandle == false) die ('Unable to open database');

        $dbquery = "SELECT * FROM usernames WHERE username=trevor";
        $dbresult = sqlite_query($dbhandle, $dbquery);

        echo sqlite_fetch_single($dbresult);
        sqlite_close($dbhandle);
?>

Answer 1

As you have access to the database (your code doesn't die ) , I'd say there's got to be an error later ;-)

Looking at your SQL query, I see this :

SELECT * FROM usernames WHERE username=trevor

Are you sure you don't need to put quotes arround that string ?
Like this :

SELECT * FROM usernames WHERE username='trevor'

Also, notice that sqlite_fetch_single will only fetch the first row of your data -- which means you might need to use sqlite_fetch_array or sqlite_fetch_object if you want to access all the fields of your resulset.
