PHP Replace where needed ONLY

[Valleriani]

Right now I have this set of code

 

for ( $counter = 1; $counter <= $count; $counter += 1) {
$content['post_content'] = str_replace($pieces[$counter], '<strong>' . $pieces[$counter] . '</strong>', $content['post_content']);
}

 

What it does is change any keywords in the content to have a bold feel to it, pretty simple enough.

 

The issue is, sometimes the keyword is in image links or links in general, for example:

$content['post_content'] = There is a bull here, a big bull! <img src="www.bigbull.com">

 

Generally it should just bold the two first ones, but not the last one (One's in < >'s basically shouldn't be).. Right now it would come out like <img src="www.big<strong>bull</strong>.com"> Which is a nasty booboo...

 

Can anyone help me out, or give me advise on how to zap this issue? Thanks!

This is how I think you could do it

 

Keep that initial for loop.

 

Then do a search to find the location of the keyword. If it finds the location  Check the first character after and before the keyword, if before is a Space, after is a space, OR before is a period after is a space, OR before and after are spaces, then it isn't a part of a link like that.

 

Then you can add the strong.

 

Repeat that for all occurances of the keyword.

 

Something like that should work.
