Why not go for a simpler solution? If the position of the text to be
interpolated inside the other is fixed, it will be simpler to just refer to the
variable there, e.g.:
$name = 'John Q. Public';
$salutation = "Hello $name!, how is the weather over there?";
If what you need is to replace an existing fixed part, then str_replace() would
be the way to go:
$salutation = str_replace('[NAME]', $name, 'Hello [NAME]!, how is the weather
over there?');
Yet another possibility is simple concatenation:
$text = 'Hello !, how is the weather over there?';
$salutation = substr($text,0,6).$name.substr($text,6);
When trying to solve something, I tend to use the KISS approach. Usually the
simpler solution is the one needed (Occam's razor)
BTW, I do not see what this has to do w/ OOP in PHP <grin>, and string
interpolation, concatenation and replacement are all already discussed in the
_fine_ PHP manual.
If the bits to be replaced or extracted for concatenation are variable but
follow a patterns, then use any of the preg_* functions (ereg* are OK, but
usually slower and the regexes not as rich).
Cheers.
