fseek — Seeks in a file.
int fseek(file_handle, offset);
resource file_handle: File
int offset: Offset in
0 on success; -1 on error
Moves file pointer from its current position to a new
position, forward or backward, specified by the number of
bytes. You can determine the current position by using ftell() . This function
doesn't operate on file pointers opened using FTP or
HTTP. Note that seeking past EOF is not considered an
error, but the file position is changed (even if
invalid). When trying to seek before the start of the
file, fseek() fails.
Example 326. Print every
second character from a file
$fh = fopen("test.txt", "r");
$a = 0;
$a = $a + 2;
