Menu
Ive written a script to send html emails and all works well. I have the email stored in a separate HTML file which is then read in usin a while loop and fgets(). However, i want to be able to pass variables into the html. For example, in a html file i may have something like..
<body>
Dear Name <br/>
Thank you for your recent purhcase
</body>
and i read this into a string like so
$file = fopen($filename, "r");
while(!feof($file)) {
$html.= fgets($file, 4096);
}
fclose ($file);
I want to be able to replace "Name" in the html file by a variable and im not entirely sure on the best way to do this. I could always make my own tag and then use regex to replace that with the name once ive read the file into the string, but im wondering if there is a better/easier method to do this.
(On a side note, if anyone knows whether its better to use file_get_contents instead of multiple calls to fgets, id be interested to know)

str_replace() also has the disadvantages of potentially matching and replacing things that you might not want to. Smarty is definitely overkill for this, I would follow Matt's suggestion above by doing something like the following
function getEmailContents(array $vars) {
extract($vars);
ob_start();
include 'email.html.php';
return ob_get_clean();
}
email.html.php would look like this
<body>
Dear <?php echo $name; ?> <br/>
Thank you for your recent purhcase of <?php echo $product; ?>
</body>
and you can call it like this
$emailContents = getEmailContents(array('name' => 'El Yobo', 'product' => 'Something'));
You'll never match anything by mistake this way and it's easily extended with other variables etc. without having to use addition str_replace() calls.
If you need to go much further than that, it might be worthwhile looking at Smarty.

You could use str_replace() to define placeholders like
Dear %name
Thank you for your recent purchase of %product
and then replace them on the fly:
$html = str_replace("%name", $order_name, $html);
$product = str_replace("%product", $order_product, $html);
Using file_get_contents() or fopen() is both all right.
