Question

i have a long string that can hold all these values at the same time:

hello<!>how are you? <!>I am fine<!> What is up? <!> Nothing!

I need to find all these posibilities:

' <!> '
' <!>'
'<!> '
'<!>'

And replace them with “\n”

Can that be achieved with str_replace in php?

Answer 1

If you only have those 4 possibilities, yes, then you can do that with str_replace.

$str = str_replace( array( ' <!> ', ' <!>', '<!> ', '<!>' ), "\n", $str );

Yeah, but what if there is two spaces ? Or a tab ? Do you add a spacial case for each ?

You can either add special cases for each of those, or use regular expressions:

$str = preg_replace( '/\s*<!>\s*/', "\n", $str );
