php : use str_replace( ); on some condition?

my text:

bob have message123 and alice has message

i want:

bob have newmessage and alice has newmessage

My current code is:

$fullText= str_replace("message123", "newmessage", $fulltext);
$fullText= str_replace("message", "newmessage", $fulltext);

but it becomes:

bob have newnewmessage and alice has newmessage

Use the strtr() function -- it will not pass again over stuff that it already replaced:

$fullText = 'bob have message1 and alice has message without 1.';
$fullText = strtr( $fullText, array(
    "message1" => "newmessage",
    "message" => "newmessage" ) );

For the simplest solution, you could just add spaces:

$fullText= str_replace(" message1 ", " newmessage ", $fulltext);
$fullText= str_replace(" message ", " newmessage ", $fulltext);

Or using multiple needles:

$fullText = str_replace(array(' message1 ', ' message '), array(' newmessage ', ' newmessage '), $fullText);

You could always use preg_replace.

In this case:

$fullText=preg_replace("/\bmessage[0-9]*/", "newmessage", $fullText);

which will replace message, message1, message2 etc.
