HTML elements in PHP - php

Question

I am very new to PHP, so be gentle.
It seems I cant run HTML in PHP.
For example when I try to
echo "<script> success(); </script>";
Result will be:
<script> success(); </script>
Another example:
$msg2 = "<b>Dear</b> ".$name ."\n\n" ."Thank you for your registration, we will be contacting you within 48h."."\n\n" ."Yours ....";
Result will be:
<b>Dear</b> (name of the client)
Thank you for your registration, we will be contacting you within 48h.
Yours ....
I checked the meta its:
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
I will give You guys the code ( some of it is in Estonian )
<?php
if (isset($_REQUEST['email'], $_REQUEST['nimi'], $_REQUEST['koolitus'], $_REQUEST['telf'], $_REQUEST['kuupaev'], $_REQUEST['tingimused'])) {
$admin_email = "ville.madison#gmail.com";
$email = $_REQUEST['email'];
$koolitus = $_REQUEST['koolitus'];
$nimi = $_REQUEST['nimi'];
$kuupaev = $_REQUEST['kuupaev'];
$telf = $_REQUEST['telf'];
$marked = $_REQUEST['marked'];
$kodulehemail = "koolitused#registreerumine.ee";
$koolitaja = $_REQUEST['koolitaja'];
$beauty = "info#beautyfactory.ee";
$msg = "Koolitusele registreerumine: " . $koolitus . "\n" . "Soovitud koolitaja: " . $koolitaja . "\n\n" . " Nimi: " . $nimi . "\n" . " Email: " . $email . "\n" . " Telefon: " . $telf . "\n" . " Soovitud kuupäev (aaaa-kk-pp): " . $kuupaev . "\n\n" . "Märked: " . $marked;
$msg2 = '<b>Hea</b> ' . $nimi . "\n\n" . "Täname Teid koolitusele broneerimast, teatame Teile registreeringu kinnitamisest 48h jooksul." . "\n\n" . "Teie Beauty Factory";
mail($admin_email, "Koolitusele registreerumine", $msg, "From:" . $kodulehemail);
mail($email, "Koolitusele registreerumine", $msg2, "From:" . $beauty);
}
?>
At the moment there is only one word that I am trying to make in bold for the sake of testing. But when I get it working I will start editing it more and I want to echo a javascript function in the php if statement.
I have tried using single quotes, double quotes and the:
nl2br(htmlentities($msg2));
None of it works

Answer 1

The message you send is not interpreted as HTML. The default
header of the mail function is text/plain.
If you want your customers to see the bold text, you must specify the content-type as HTML in the message header.
<?php
// Set the content type of the email to HTML (and UTF-8)
$header = 'Content-type: text/html; charset=utf-8' . "\r\n";
// Add the from field
$header .= 'From: ' . $beauty . "\r\n";
// Send email
mail ($email, "Koolitusele registreerumine", $msg2, $header);
?>
However you will not be able to use Javascript as it is intepreted client side. PHP does not interpret Javascript, and most of the mail clients will not execute Javascript for obvious security reasons.

Here is a sample example of how to use html tags in php:
<?php
var $name = "xyz";
var $email = "xyz#gmail.com";
echo '<table border="1" style="width:20%">';
echo '<tr><th>UserName</th><th>Email</th></tr><tr><td>';
echo $name."<br>";
echo '</td><td>';
echo $email."<br>";
echo '</td></tr></table>';
?>
This is basic php and html table format example,you can follow this for write html tags.

Answer 3

The problem was that the function mail() had a default content of text/plain, just needed the $header to make text/html. Thanks guys for your quick answers !
