php: how to replace all string values by variables values?

Question

I am using that kind of html template:

Hello {{username}}, my email is {{email}} and my age is {{age}}

(number of {{variables}} is dynamic)

I would like to autoamtically parse the template and replace all {{variables}} by their php variable content

ex:

$username="Peter"; $email="myemail";$age=20;

so it should render like :

$res = render("template.html", array("username"=>$username, email=>$email, age=>$age));

Hello Peter; my email is myemail and my age is 20

Have you considered using something like Twig instead of reinventing the wheel? ;) — lxg

This task would be solved much easier and more elegant by means of a HEREDOC definition, but the syntax for your template would have to be slighty different: php.net/manual/en/… — arkascha

how about using <?=$username?> instead of {{username}} ? — xmike

you can consider replacing all '{{' with '$' and '}}' with ''. If you are using vim editor try this: :%s/{{/$/gc :%s/}}//gc — JammuPapa

You could do it like this:

function render($template, $vars) {
    $template = file_get_contents($template);
    $search  = [];
    $replace = [];
    foreach ($vars as $key => $value) {
        $search[] = '{{'.$key.'}}';
        $replace[] = $value;
    }
    return str_replace($search, $replace, $template);
}

Although if you want more complexity you should use something like Handlebars:

etc

Try this.

function render($template,$values){
    $data=file_get_contents('templates/'.$templates); //templates/ is just templates path. you can change it.

    foreach ($values as $key => $value) {
        $data=str_replace('{{'.$key.'}}', $value, $data);
    }

    return $data;
}
