5 years ago
Hello i have this function for languages using php
function lang($var){
return $var;
}
when i write
<?php echo lang("test lang"); ?> the function output will return ( test lang )
so now is my question how can i use this function inside javascript without creating another languages function to use it inside javascript, all i need is i want to convert or another idea to use php function inside js files.
Kind regards.

You can run a PHP file and get the results of anything you echo.
Or you can put it in a <script> tag
<script>
var lang="<?php echo lang("test lang"); ?>";
</script>
The big difference is when the function runs. In the first it runs after the current page is requested/loaded. In the second it runs while the page is being rendered.

You can't.
Javascript runs in the user's browser.
PHP runs on the server. It reads your .php files, runs PHP that it finds, sends HTML to the browser, and exits.
There is no "spooky action at a distance" that allows you to run PHP code from within the Javascript code.
Unsure what you are trying to accomplish. You could use Ajax to send some data to your PHP server. But it will run a new script.
Maybe you mean you want PHP to process JS files before they are sent. That is a PHP question, but I think was recently answered here. JS files aren't normally processed by PHP, but apparently there is a way to configure PHP to do so. Google is your friend. Or ask on a PHP forum.

Thanks for your replay dear watusiware
bro in one of my project my php language file was as array when i was to get something i was get it like this
php
- $lang = array (
- "Hi_there" => "Hi there"
- );
js
- var js_lang = <?php echo json_encode( $lang ) ?>;
so i was putting json_encode(); before my js scripts, so i was using my php languages inside js like this.
js
- alert(js_lang("Hi_there")); //Out put is Hi there
but my problem is in my new project i do function for inside php language (NOT ARRAY) like i was do in old project.
So if i cann't do what i asking about, what should i do please?

You need help from a PHP FORUM. We can help you with jQuery.
You need to configure your PHP server to allow you to use PHP in your JS files. It is not configured for this by default.
I do not use PHP. I only know this because somebody answered the same question a few days ago. Unfortunately, I can't find that post.

You need to use Ajax or simply getJSON. You can look up a phrase or phrases that way. Even if it comes from a database.
The problem has nothing to do with PHP, it is a general server question.

It was good chatting with you. I looked up file_exists. It can not be passed an URL. Only the path to the avaliable_languages.php file with a relative path that gets to the correct folder.

Yes bro now it's working with
D:/wamp64/www/project_name/includes/languages/avaliable_languages.php
But i want to do something more dynamic with this path!
Thanks for your answers guys :)

You can use a relative or short path. But it depends where this PHP is.
if it is in D:/wamp64/www/project_name/check.php you can use the short name includes/languages/avaliable_languages.php .

For anyone who comes to this thread, we used a variation of the first answer. No Ajax. No delays for the user.
- <?php
- $lang = array("success" => lang("success"),"danger" => lang("danger") );
- function lang($word){
- // use your real lang function!
- return "OK";
- };
- ?>
- <script>
- var lang=<?php echo json_encode($lang); ?>;
- alert(lang.success)
- </script>

Jake answer was good, and gives me more ideas.
-------------------------------------------------------------------
In this code i just make it easy to add keys, but i'm trying to access $lang outside the lang () function, then i never will need to add keys like what i did in line 10.
So I'm upset from $language_code_avaliable array in line 10 
, i want to make this script more dynamical 
, i want to make this script more dynamical Any ideas to make this script more dynamical without add and remove keys!
- <?php
- function lang($key){
- $lang = array (
- "lang_name" => "En",
- "Hello_user" => "Hello user :)"
- );
- return $lang[$key];
- }
- $language_code_available= array("lang_name","Hello_user");
- $langs = array();
- for($i=0; $i <= count($language_code_available) - 1; $i++){
- $langs[$language_code_available[$i]] = lang($language_code_available[$i]);
- }
- ?>
- <script type="text/javascript">
- var js_lang = <?php echo json_encode($langs) ?>;
- alert(js_lang['lang_name']);
- </script>
Because this is not a PHP forum. Please consider the question closed. If you need PHP help or ideas you should use a PHP forum or just ask me personally.
