hi andras-
consider the strstr() and strrstr() functions :
$str = 'abcabc';
print strpos ($str,'b'); // 1
print strrpos($str,'b'); // 4
these positions can be used with other functions, such as substr() :
$str = 'abc.png';
print strpos($str,'.'); // 3
print substr($str,strpos($str,'.')); // .png
print substr($str,strpos($str,'.')+1); // png
print substr($str,0,strpos($str,'.')); // abc
and it's good to keep in mind that foo.tar.gz and foo.bar.eh.boo may give
unexpected results so choose your logic wisely :)
and as already stated, split() and explode() would work too :
$str = 'abc.png';
$pieces = explode('.',$str);
print $pieces[0]; // abc
print $pieces[1]; // png
also, depending on what you're doing, something like the following may be
appropriate as it'll check the end of $str for a desired ending :
if (eregi('(gif|jpg|png|jpeg)$',$str)) {
print 'yes, variable $str ends with gif, jpg, png or jpeg';
}
warm regards,
Philip Olson
