I would like to replace just complete words using php
Example : If I have
$text = "Hello hellol hello, Helloz";
and I use
$newtext = str_replace("Hello",'NEW',$text);
The new text should look like
NEW hello1 hello, Helloz
PHP returns
NEW hello1 hello, NEWz
Thanks.
You want to use regular expressions. The \b
matches a word boundary.
$text = preg_replace('/\bHello\b/', 'NEW', $text);
If $text
contains UTF-8 text, you'll have to add the Unicode modifier "u", so that non-latin characters are not misinterpreted as word boundaries:
$text = preg_replace('/\bHello\b/u', 'NEW', $text);
