@ sylvain at abstraction dot fr : Afraid not, your code won't work on 32-bit PHP compilation, even if you try to bypass it that way. Another approach is as follows, which doesn't work either [guess internal pointer or something similar in PHP's fseek() still uses 4-byte signed integer, so no matter what we try it doesn't seek] : function file__fseek_safe ( $file_handler , $position ) { if ( bccomp( $position, "2147483647" ) == 1 ) { if ( ( $return = fseek( $file_handler, 0, SEEK_SET ) ) != 0 ) { return $return; } while( bccomp( $position, 0 ) == 1 ) { $_bytes = "2147483647"; if ( bccomp( $_bytes, $position ) == 1 ) { $_bytes = $position; } if ( ( $return = fseek( $file_handler, intval( $_bytes ), SEEK_CUR ) ) != 0 ) { return $return; } $position = bcsub( $position, $_bytes ); } return 0; } else { return fseek( $file_handler, intval( $position ), SEEK_SET ); } } ---- Server IP: 69.147.83.197 Probable Submitter: 78.182.217.52 ---- Manual Page -- http://www.php.net/manual/en/function.fseek.php Edit -- https://master.php.net/note/edit/101033 Del: integrated -- https://master.php.net/note/delete/101033/integrated Del: useless -- https://master.php.net/note/delete/101033/useless Del: bad code -- https://master.php.net/note/delete/101033/bad+code Del: spam -- https://master.php.net/note/delete/101033/spam Del: non-english -- https://master.php.net/note/delete/101033/non-english Del: in docs -- https://master.php.net/note/delete/101033/in+docs Del: other reasons-- https://master.php.net/note/delete/101033 Reject -- https://master.php.net/note/reject/101033 Search -- https://master.php.net/manage/user-notes.php
