#16751 — Regular Express - preg_replace - matching whole phrases

Hi 

I am doing some replacements on text using arrays e.g.

$text="Everyone loves apple and banana smoothies";
$searcharray=array("/\bBanana\b/i","/\bApple\b/i","/\bTomatoes\b/i");
$replacearray=array("Toffee","Soup","Breadsticks");

$newtext=preg_replace($searcharray,$replacearray,$text);


I'm using \b so that only full words are replaced and \i to make the match case insensitive.

It all works fine - but when I want to search for, say...

       Pineapple...

i.e. a word with punctuation after it, it doesn't work.

I've tried escaping the .s to no avail...

Any ideas?

Many thanks
Steve

add a 'u'
$text="banana's";
$searcharray=array("/\bBanana.s\b/ui");
$replacearray=array("Toffee");
$newtext=preg_replace($searcharray,$replacearray,$text);
print $newtext;

(You mean /i)

Maybe you left the \b in there?  Maybe you did not escape the escape
character correctly?  Much better to show what did not work.

  "\bBanana\\.\\.\\."

works for me.
