Question

I have a php function that generates HTML code like below

function j_uf_SomeFunction($some_var) {
    ?><div class="db_photo">
        <img alt="<?php echo some_php_function ?>" src="<?php echo $some_var; ?>" />
    </div><?php
}

Of course, its much more advanced and add all sorts of user options.

In most case I place this function inline, as opposed to have to append it to a string. However, I’ve come to the first occurrence (probably not the last occurrence) where I need to store the rendered HTML in a string and not have it sent straight off to the parser for building the page.

I need to cut the function off and tell it to take the html generated and store it in a string, and not send it off to the page, only on certain situations.

Answer 1

function j_uf_SomeFunction($some_var) {
    ob_start();
    ?><div class="db_photo">
        <img alt="<?php echo some_php_function ?>" src="<?php echo $some_var; ?>" />
    </div><?php
  return ob_get_clean();//suggestion by GWW
}

ob_start() is starting buffer receive
ob_get_clean() cleans current buffer and returns its value.
