  • 0

I have tried to use templates to be able to make a multilingual web site, so i created a folder called languages containing en.php and fr.php
here is the code for en.php:

<?php
class Index {

    public $filename;
    public $assigned_vars = array();

    public function set($key, $value) {
        $this -> assigned_vars[$key] = $value;
    }

    public function display() {
        if (file_exists($this -> filename)) {
            $output = file_get_contents($this -> filename);
            foreach ($this->assigned_vars as $key => $value) {
                $output = preg_replace('/{' . $key . '}/', $value, $output);
            }
            echo $output;
        } else {
            echo "*** Missing template ***";
        }
    }

}

$index = new Index;
$index -> filename = "templates/index1.php";
$index -> set('page_title', "Welcome");
$index -> set('first_name', "Welcome to our website.");
$index -> display();
?>

and here is the code for fr.php:

<?php
class Index {

    public $filename;
    public $assigned_vars = array();

    public function set($key, $value) {
        $this -> assigned_vars[$key] = $value;
    }

    public function display() {
        if (file_exists($this -> filename)) {
            $output = file_get_contents($this -> filename);
            foreach ($this->assigned_vars as $key => $value) {
                $output = preg_replace('/{' . $key . '}/', $value, $output);
            }
            echo $output;
        } else {
            echo "*** Disparus modèle ***";
        }
    }

}

$index = new Index;
$index -> filename = "templates/index1.php";
$index -> set('page_title', "Bienvenue");
$index -> set('first_name', "Bienvenue sur notre site.");
$index -> display();
?>

then i created a folder called templates and created a file called index1.php

and here is index1.php:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en">
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
        <title>{page_title}</title>
    </head>
    <body>
        {first_name}
        <br/>
        <a href="?lang=en-us">english</a>
        <a href ="?lang=fr">French</a><br />
        <?php
        echo strftime("Y", time());
        ?>
    </body>
</html>

and then i created the regular index.php
and here is the code for index.php:

<?php
if (isset($_GET['lang'])) {
    setcookie('language_test', $_GET['lang'], time() + (60 * 60 * 24 * 7));
    if ($_GET['lang'] == "fr") {
        require ('languages/fr.php');
    } else {
        require ('languages/en.php');
    }
} else {
    require ('languages/en.php');
}
?>

here is my problem when i try to show index.php in my browser it works fine but the php code in index1.php doesn’t show any of this strftime();, but when i try to view the source of this
index.php
it’s showing me this:

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en">
    <head>
        <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
        <title>Welcome</title>
    </head>
    <body>
        Welcome to our website.
        <br/>
        <a href="?lang=en-us">english</a>

        <a href ="?lang=fr">French</a><br />
        <?php
        echo strftime("Y", time());
        ?>
    </body>
</html>

thanks in advance. and sorry for being so long and sorry for my awful english.

    When you are invoking file_get_contents($this -> filename); it just converts strftime("Y", time()); part as string. So it does not execute.

    In the index1.php you should use {time} instead of 

    <?php
echo strftime("Y", time());
?>

    So It’ll look like 

    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <title>{page_title}</title>
</head>
<body>
    {first_name}
    <br/>
    <a href="?lang=en-us">english</a>
    <a href ="?lang=fr">French</a><br />
    {time}
</body>

    Now add time in en.php or fr.php like bellow

    $index -> set('time', strftime("%Y", time()));

    Its better not to re-invent a template library. There are plenty available. See this blog post top 25 php template engines
