What I'm trying to do, is to get all the error phrases into some kind of array or object or class or something that I can easily use in my PHP script.

At the moment I am using the following query to get all the phrases of phrasetype 'error':

SELECT * FROM Phrase JOIN Phrase_Language USING(PhraseID) JOIN Language Using(LanguageID) WHERE Language = 'en' AND PhraseType = 'error';

This gets me what I need, but I'm not sure how to get it into an object or something that I can maybe query like this:

$phraseError->regexNameError->NativePhrase

Because what I need is the NativePhrase. And I've grouped them by PhraseType so that I don't have to load the whole table into my query, and I only get what I need. - Got this tip from another thread.

What I am ultimately after is to have as little queries as possible, so that my site isn't slowed down by multiple (/duplicate) queries all over the show, but also not to have long queries that contain info which I don't necessarily need on the current page.

Answer 1

This should work -

<?php
    //Selecting only the Phrase and the NativePhrase columns.
    $query = "SELECT Phrase, NativePhrase FROM Phrase JOIN Phrase_Language USING(PhraseID) JOIN Language Using(LanguageID) WHERE Language = 'en' AND PhraseType = 'error'";

    //Run the query.
    $res = $db->query($query) or die(mysqli_query($db));

    $PhraseError = Array();

    while($row = $res->fetch_assoc()){
        $PhraseError[$row['Phrase']] = $row['NativePhrase'];
    }

    /*
        This will now allow you to search like this,
        echo $PhraseError['regexSurnameError'];
        //will return the nativePhrase for that.
    */
?>
