This is pretty simple is do.
There are a number of ways you can do this. I will give you an example of how this can be done using link entries that are located in a flat text file ->
Code:
Egypt|yourpage.com/egypt.html
Osiris|yourpage.com/osiris.html
Ok, the above would be the link_data.txt file. This file will hold all your link data, or data you want to link from your articles. The data to the left of the pipe will be the link names and the data to the right of the pipe is the actuall links.
Each entry is on its own line in the file (no whitespace inbetween lines)
PHP Code:
function link_data( $string ) {
$data = file( 'link_data.txt' );
foreach ( $data as $val )
{
$chunks = explode( '|', trim( $val ) );
$find = trim( $chunks[0] );
$replace = '<a href="' . trim( $chunks[1] ) . '">' . $find . '</a>';
if ( strstr( $string, $find ) )
{
$string = str_replace( $find, $replace, $string );
}
}
return( $string );
}
The above is your function. Call the function as so ->
PHP Code:
$string = 'Hi, this article is about Osiris. He was a great man in ancient Egypt blah blah blah';
$data = link_data( $string );
---------------------------------------------------
There are many other ways this can be done also, this is only a simple way of doing it. If you need the words to be case insensative, then replace the str_replace() with preg_replace() or other reg exp.......
