PHP :: Simple PHP Excerpt

simple-excerpt.php

<?php
/**
 * $pos = get cut position based on fixed position ($fixed),
 * but without break last word
 */

$text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit.";
$excerpt = '';

$fixed = 25;

if(strlen($text) >= $fixed)
{
	$pos = strpos($text, ' ', $fixed);
	$pos = $pos ? $pos : strlen($text);
	$excerpt = substr($text,0,$pos);

	// delete last non alphanumeric character (save ">" if you want to save html tag)
	$excerpt = preg_replace('/[`!@#$%^&*()_+=\-\[\]\';,.\/{}|":<>?~\\\\]$/', '', $excerpt);
}

$excerpt = $excerpt == '' ? $text : $excerpt;

echo fix_unclosed_html_tag($excerpt);

function fix_unclosed_html_tag($string) {
	if(trim($string) == '') return '';

	libxml_use_internal_errors(true);
	$dom = new DOMDocument();
	$dom->loadHTML(mb_convert_encoding($string, 'HTML-ENTITIES', 'UTF-8'));

	return $dom->saveHTML($dom->getElementsByTagName('div')->item(0));
}

This doesn't work with unicode. Instead of removing non-ASCII/English letters/numbers just remove ending ,.'[]{}()!@#$%^&*()_+ etc...

Hi Xeoncross, thanks for your help!, i have updated the code 👍
