Question

Just a simple question. I have a contact form stored in a function because it’s just easier to call it on the pages I want it to have.

Now to extend usability, I want to search for {contactform} using str_replace.

Example:

function contactform(){
  // bunch of inputs
}

$wysiwyg = str_replace('{contactform}', contactform(), $wysiwyg);

So basically, if {contactform} is found. Replace it with the output of contactform.

Now I know that I can run the function before the replace and store its output in a variable, and then replace it with that same variable. But I’m interested to know if there is a better method than the one I have in mind.

Thanks

Answer 1

Your method is fine, I would set it as a $var if you are planning to use the contents of contactform() more than once.

It might pay to use http://php.net/strpos to check if {contact_form} exists before running the str_replace function.

You could try both ways, and if your server support it, benchmark:

<?php echo 'Memory Usage: '. (!function_exists('memory_get_usage') ? '0' : round(memory_get_usage()/1024/1024, 2)) .'MB'; ?>
