PHP: Set variable in to include file in 'if' statement

Question

I am trying to set a variable in an if statement so that only when the if statement is true, the variable will be set and will be able to be used further down on the page.

Here's what I have tried:

if ($row[8] == 1) {
    echo 'Message here';
    ob_start();
    include('F164.php');
    $f164 = ob_get_clean();
}

as well as:

if ($row[8] == 1) {
    echo 'Message here';
    $f164 = include('F164.php');
}

Why dont these work, can you include the errors that you care getting? — Chase

What are you trying to set the variable to? Why don't you put a function in the include file, and call the function? — Barmar

@Chausser When using ob_start(); include('F164.php'); $f164 = ob_get_clean(); the file simply does not show up. When using $f164 = include('F164.php'); it does, but where it is declared, not where the variable is further down on the page. — swiftsly

What does the if statement have to do with this? The way you're trying to set the variable won't work outside the if, either. — Barmar

@Barmar I would like the "if" statement to set the variable $f164 to include('F164.php'); only if $row[8] == 1. — swiftsly

new answer:

<?php
if ($example === 123) {
    ob_start();
    include 'file_with_output.php';
    $var = ob_get_contents();
    ob_end_clean();
}
?>

Just tried, this works for me.

If this does not work for you, please give an example content of the included file.

old answer:

I assume the value of the variable is in the F164.php file. You can assign it by returning the value in the included file:

F164.php looks like this:

<?php
    $somevar = 'lolvalue';
    return $somevar;
?>

Code:

if ($example == true) {
    $var = include 'F164.php';
}

Means: If $example is true, $var will get the value 'lolvalue'.

Edit:

After reading your question again and again, i'm not sure if we mean the same thing. Still hope i could help.

Actually that sets $example to true... You missed an equals sign ;)

Let's say the file the code is from is called "header.php." "F164.php" is a file with <div>'s that are supposed to be displayed at the bottom of the "header.php" if $row[8] == 1, but the code in the original question is up near the top. Also, please note, and I should have said this before, "F164.php" has no variables declared at this time.
