[Resolved] replace several substrings

[aconway]

I am trying to use the ereg_replace to replace substrings in a string. I am having problems when there are several different substrings that I want to replace... example:

If I do this:

$string = 'See the Cat';

$newstring = ereg_replace('Cat','<a href=\'cat.php\'>Cat</a>',$string);

echo $newstring;

It works fine, but I have scenarios where

$string = 'See the Cat, Dog and Monkey';

and I want a link to the Dog and Monkey as well.

I came across a thread that did something like this:

$foo = array(
     "Cat"  => "<a href=\"cat.php\">Cat</a>",
     "Dog" => "<a href=\"dog.php\">Dog</a>",
     "Monkey" => "<a href=\"monkey.php\">Monkey</a>"
   );
   $newstring = ereg_replace(array_keys($foo),array_values($foo),$string);
   echo $string;

But, I can't get it to work, and it looks like it will only replace one of the items... but, I could be wrong 🙂

Solved it:

echo eregi_replace("(Cat|Dog|Monkey)","<a href='\\\\1.php'>\\\\1</a>",$string);

I know I marked it resolved, but I have another question. So... PLEASE READ THIS

I came to another scenario where I have: Sea Horse

Now the a tag comes out like this

<a href="Sea Horse.php">

two problems the capitals and the space, any ideas on how to remove the space and change to lower case only within the url?

I didn't think about the upper case before.

I tried to use this

ereg_replace("(Cat|Dog|Monkey|Sea Horse)","<a href=".strtolower('\\\\1').".php>", $string);

But it doesn't turn it to lower case

ANY HELP PLEASE!!
