PHP之间的动态变量名称

Question

I have a badly designed Database that I have to deal with. In order to have a smaller code footprint, I need to use dynamic variable naming in PHP. However, the names of each variable vary greatly. Here's a sample of my code:

<?php

    $test = (object)[
        'variable_1_text'   => 'ONE',
        'variablevv_1_another_one'   => 'Two',
        'variablett_1_blah'   => 'III',
        'variablex_1_text_lala'   => 'Four',
        'variable_2_text'   => 'ONE',
        'variablevv_2_another_one'   => 'Two',
        'variablett_2_blah'   => 'III',
        'variablex_2_text_lala'   => 'Four',
        'variable_3_text'   => 'ONE',
        'variablevv_3_another_one'   => 'Two',
        'variablett_3_blah'   => 'III',
        'variablex_3_text_lala'   => 'Four',
        'variable_4_text'   => 'ONE',
        'variablevv_4_another_one'   => 'Two',
        'variablett_4_blah'   => 'III',
        'variablex_4_text_lala'   => 'Four',
    ];

    //this doesn't work
    foreach (array(1,2,3,4) as $temp_val) {
        echo $test->variable_{$temp_val}_text . "<br />";
        echo $test->variablevv_{$temp_val}_another_one . "<br />";
        echo $test->variablett_{$temp_val}_blah . "<br />";
        echo $test->variablex_{$temp_val}_text_lala . "<br />";
    }

?>

There's a lot of these variables. I just need how to dynamically make those 1, 2, 3, and 4 in between the names of the variable names. Is this even possible?

You can try this: $test->{'variable_'.$temp_val.'_text'};
