View Full Version : [PHP] file_get_contents

Hi everyone,

Doing a site for which the homepage will have three main sections on it (e.g., about, donate, contact).

For those sections, there will be three other pages (about.htm, donate.htm, and contact.htm).

For the about section of the homepage, for example, I would like to have, say, the first 50 words from the div called "content-container" in "about.htm" and have those words written in the about section on the homepage, with like, an ellipsis at the end (...) and then a 'read more' link which links to about.htm

I was fooling around with file_get_contents but didn't really get anywhere (I suck at .PHP :D).

If anyone could help me out, that'd be great.

Thanks!

Each character is a byte, so where it says max_len, you can do 50 * avg. # of characters in each word...

That's rather a stupid idea. You should use some other function (scan through the list on that php site), which reads each word and increments your counter...

Well - I think I can just use strlen or whatever and just substring to get the 50 characters - but how would I start at '<div id='container'> and end at the next '</div>'?

Thanks for your help. Managed to get it on my own using some basic brainstuff.



$the_file = $page . '.htm';
$file_contents = file_get_contents($the_file);
$search_haystack = htmlspecialchars($file_contents);
/////
$beginning_search_needle = '&lt;div id=&quot;' . $div_id_name . '&quot;&gt;';
$beginning_search_needle_length = strlen($beginning_search_needle);
$beginning_search_needle_position = strpos($search_haystack, $beginning_search_needle) + $beginning_search_needle_length;
$search_haystack = substr($search_haystack, $beginning_search_needle_position);
/////
$end_search_needle = '&lt;/div&gt;';
$end_search_needle_length = strlen($end_search_needle);
$end_search_needle_position = strpos($search_haystack, $end_search_needle);
$search_haystack = substr($search_haystack, 0, $end_search_needle_position);
/////
$search_haystack = substr($search_haystack, 0, $content_length);
if($search_haystack{strlen($search_haystack)-1} == '.') {
$search_haystack = substr($search_haystack, 0, strlen($search_haystack)-1);
};
//////
$final_contents = $search_haystack;
$final_contents.= '... ' . '<a href="' . $the_file . '">' . 'Read More.' . '</a>';
echo $final_contents;
