note 118905 added to function.strpos

It is interesting to be aware of the behavior when the treatment of strings with characters using different encodings. <?php # Works like expected. There is no accent var_dump(strpos("Fabio", 'b')); #int(2) # The "á" letter is occupying two positions var_dump(strpos("Fábio", 'b')) ; #int(3) # Now, encoding the string "Fábio" to utf8, we get some "unexpected" outputs. Every letter that is no in regular ASCII table, will use 4 positions(bytes). The starting point remains like before. # We cant find the characted, because the haystack string is now encoded. var_dump(strpos(utf8_encode("Fábio"), 'á')); #bool(false) # To get the expected result, we need to encode the needle too var_dump(strpos(utf8_encode("Fábio"), utf8_encode('á'))); #int(1) # And, like said before, "á" occupies 4 positions(bytes) var_dump(strpos(utf8_encode("Fábio"), 'b')); #int(5) ---- Server IP: 72.52.91.14 Probable Submitter: 177.205.100.168 ---- Manual Page -- http://php.net/manual/en/function.strpos.php Edit -- https://master.php.net/note/edit/118905 Del: integrated -- https://master.php.net/note/delete/118905/integrated Del: useless -- https://master.php.net/note/delete/118905/useless Del: bad code -- https://master.php.net/note/delete/118905/bad+code Del: spam -- https://master.php.net/note/delete/118905/spam Del: non-english -- https://master.php.net/note/delete/118905/non-english Del: in docs -- https://master.php.net/note/delete/118905/in+docs Del: other reasons-- https://master.php.net/note/delete/118905 Reject -- https://master.php.net/note/reject/118905 Search -- https://master.php.net/manage/user-notes.php
