Problemas con mod write en Apache

[Jhon Silver]

He subido el archivo .htacces y archivo adjunto para crear urls amigables tipo teclado-virtual.php en vez php?id=14
Las urls se ven amigables pero me aparecen una serie de lineas en las que dice

Deprecated: Function ereg_replace() is deprecated in /home/artic/public_html/seourls.php on line 23

Deprecated: Function ereg_replace() is deprecated in /home/artic/public_html/seourls.php on line 23


Os paso el código de .htaccess

Código Apache:

RewriteEngine On
 
RewriteRule ^([^/]*)/([^/]*)/$ article.php?id=$1&title=$2 [L]
RewriteRule ^profile/([^/]*)/([^/]*)/$ profile.php?a=$1&name=$2 [L]
RewriteRule ^category/([^/]*)/([^/]*)/$ category.php?id=$1&name=$2 [L]
RewriteRule ^page/([^/]*)/([^/]*)/$ page.php?p=$1&title=$2 [L]
 
RewriteRule ^start/([^/]*)/([^/]*)/$ index.php?page=$1&ipp=$2 [L]
 
RewriteRule ^category/([^/]*)/([^/]*)/start/([^/]*)/([^/]*)/$ category.php?id=$1&title=$2&page=$3&ipp=$4 [L]
 
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]{1,5}|/)$
RewriteRule (.*)$ %{REQUEST_URI}/ [R=301,L]
 

Y el código php del archivo seourls.php

Código PHP:

<?php 
 
 
 
 
 
GENERATE SEO URLS */
function generate_seo_link($input,$replace = '-',$remove_words = true,$words_array = array())
{
    //make it lowercase, remove punctuation, remove multiple/leading/ending spaces
    $return = trim(ereg_replace(' +',' ',preg_replace('/[^a-zA-Z0-9\s]/','',strtolower($input))));
 
    //remove words, if not helpful to seo
    //i like my defaults list in remove_words(), so I wont pass that array
    if($remove_words) { $return = remove_words($return,$replace,$words_array); }
 
    //convert the spaces to whatever the user wants
    //usually a dash or underscore..
    //...then return the value.
    return str_replace(' ',$replace,$return);
}
 
/* takes an input, scrubs unnecessary words */
function remove_words($input,$replace,$words_array = array(),$unique_words = true)
{
    //separate all words based on spaces
    $input_array = explode(' ',$input);
 
    //create the return array
    $return = array();
 
    //loops through words, remove bad words, keep good ones
    foreach($input_array as $word)
    {
        //if it's a word we should add...
        if(!in_array($word,$words_array) && ($unique_words ? !in_array($word,$return) : true))
        {
            $return[] = $word;
        }
    }
 
    //return good words separated by dashes
    return implode($replace,$return);
}
 
?>
 

¿Que creeis que ocurre para que aparezca las líneas de código?
Perdón por el desconocimiento
