King Php

The  plugin  for WordPress in order to control the maximum amount of characters displayed for an entry on the main page. If the set limit is surpassed a link to a page with the whole content will appear and the text on the entry will be chopped to that amount of characters, otherwise the content will be showed unchanged.

Installation
1 Download the plugin limit-post.phps to the /wp-content/plugins/ directory
2 Change the name from limit-post.phps to limit-post.php
3 Go into the plugin section on the administration site of wordpress and activate it.
4 Go into your index.php file and change the function the_content() with the_content_limit($max_characters, $link_text) where:
$max_characters: maximum amount of characters shown for an entry in the main page (index.php)
$link_text: text that is used to generate the link to the whole article.

A practical case:
Replace the line < ? the_content()?>  in the index.php file with:
< ? the_content_limit(1000, “Read more”);?>
