Re: string conversion

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 On Thu, 20 Sep 2001, Andras Kende wrote: > Hi, > > I trying to cut the last 4 char of a string but sometimes its cut 3 sometime > 4 char.... > > $pic1=$amyrow["picture"]; > $pic2 = substr("$pic1", 0, -4); > > Actually I have some pictures where I need to cut off the extensions... > > amamm.jpg > 33.jpg > 321.gif > > to > > amamm > 33 > 321 > > Is any other way than substr to do this ?? > > Thanks > > Andras > > > -- > PHP General Mailing List (http://www.php.net/) > To unsubscribe, e-mail: php-general-unsubscribe@lists.php.net > For additional commands, e-mail: php-general-help@lists.php.net > To contact the list administrators, e-mail: php-list-admin@lists.php.net >
