count caracters

[edou]

Hi,

 

I'm trying to make a website using wordpress and would like to find a way to count the amount of caracters used in a message in order to stop displaying at a certain point with a link like 'read more', linking to the specific page of this message.

 

Can anyone help.

It's probably basic, but I'm really new with php.

 

Thanks.

For characters use substr. 

For words, a regular expression.

Slight expansion upon Jessica's post: If you use UTF-8 on your site, you want to use mb_substr () instead of plain substr (). To properly support those multi-byte characters.

could you be more specific. I really know nothing about php.

 

I think the function that's now counting the following is:

 

if ( count($content) > 1 ) {

if ( $more ) {

$output .= '<span id="more-' . $post->ID . '"></span>' . $content[1];

} else {

if ( ! empty($more_link_text) )

$output .= apply_filters( 'the_content_more_link', ' <a href="' . get_permalink() . "#more-{$post->ID}\" class=\"more-link\">$more_link_text</a>", $more_link_text );

$output = force_balance_tags($output);

}

 

}

 

 

The problem with that, is that if I place pictures after my text, it won't display it unless I click 'read more'. So I'm obliged to place first my pictures, which is not so nice to see.
