Hey, guys, good afternoon. How do I use a variable from an X.php file on the Y.php page ? I want to do the following for example:
<?php
$Frase = "minha frase";
?>
On my Y page I want to get the value of one of these variables, example:
<h3>
<?php $Frase; ?>
How could I receive the result of these variables from other pages? someone would have an example?

Knowing that the file "other_file.php" has:
<?php
$frase = "abcdef";
?>
In another file (from the same directory) the variable can be included as follows:
<?php
include('outro_ficheiro.php');
echo $frase;
?>
You didn’t call me back, pal
@Júliorodrigues are both files in the same directory? The code is between the <?php tags and ?> ?
No. X file -> Assets(include) Y file is at the root
You have to set the correct directory of the file where the variable is in the incude.
After the <?php add this line: error_reporting(E_ALL);
 ini_set("display_errors", 1); and see which error appears... probably you are going the wrong way, try so include "assets/outro_ficheiro.php;"...
Thanks, Gustavo! It worked! I did via include! the problem was the way I specified the way! Thanks!
Works perfect, thank you very much. My files were a hahaha mess

By way of session.
<?php
session_start(); # Deve ser a primeira linha do arquivo
$frase = "Minha Frase";
$_SESSION['frase'] = $frase;
?>
<?php
session_start(); # Deve ser a primeira linha do arquivo
echo $_SESSION['frase'];
?>
Only it returns me Warning: session_start(): Cannot send Session cookie - headers already sent by (output Started at /home/mktbt/mktbt.com/index.php:18) in /home/mktbt/mktbt.com/index.php on line 348 Warning: session_start(): Cannot send Session cache Limiter - headers already sent (output Started at /home/mktbt/mktbt.com/index.php:18) in /home/mktbt/mktbt.com/index.php on line 348
You are putting the command in the first line of your file ?
Yes, it is in the first line of my file. But now does not return the message
Using a session variable to capture variable values, above all if they are configuration values, is a bit exaggerated, and unsafe don’t you think ? A simple include would be enough. Or, you can explain in which situations the sessions are most beneficial.
He asked if there was an example. I gave an example of several, such as the use of include. Now, he didn’t specify anything in the question, so I talked about the session. He didn’t ask anything more than that. If you’re worried give a more complete answer.
Many of us have been affected in the past, and even today some are affected, due to transmitted bad practices, or unclear examples of how to correctly use a function or build decision trees, or where best fit each of them, and even today these gaps remain in many of us. That’s more or less what I meant. If you’re going to exemplify something, think 2x how it will be used in a while. It doesn’t have to be perfect, just minimally logical.
To me you just philosophized and said nothing.

Yes it is possible with

– Naldson
include('includes/controllers.php');

It is better to add more details about your problem, how it works include, pq need to pass this value to another page.
