Strpos question

Anon

I have a code to find a position of a specfic string. here is the code.

$string1 = "she is a girl, he is a boy";
$string2 = "she is a girl, (he) is a boy";
$string3 = "she is a girl, \"he\" is a boy";

echo strpos($string1,"he");

for $string1, i wanna find the position of "he", the strpos will return 1. which is the "he" inside "she", but what i want is the "he" after the word "girl".
how can i solve this problem??
Besides, for $string2 and $string3, although "he" is embraced a '()' and '""',
i want the strpos still can return a correct answer, how can i do so??
can i use regular expression in strpos??
Thank you very much.

$string2 = "she is a girl, (he) is a boy";
...
what I want is the "he" after the word "girl".

You could first find the position of "girl" within the string and then search for "he" from there. You might also want to check out preg_match. Something like the (untested) following may do what you want:

preg_match("/\b(he\b.*)$/", $string2, $match);
$pos = strlen($string2)-strlen($match[1]);

Alternatively you can forget preg match and just use the 1 from the first result as an offset for strpos() in the second search.

I think a better solution would be to search for " he" or "he " or " he ". Of course, to search the 2nd and 3rd string, you would search for he with the enclosing characters. (one or both)
