fseek()

fseek - Seeks on a file pointer

Syntax

int fseek (resource $handle, int $offset, int $whence)

Arguments

• handle - A file system pointer resource that is typically created using fopen().
• offset - The offset. To move to a position before the end-of-file, you need to pass a negative value in offset and set whence to SEEK_END.
• whence - whence values are: SEEK_SET - Set position equal to offset bytes. SEEK_CUR - Set position to current location plus offset. SEEK_END - Set position to end-of-file plus offset.

Description

Sets the file position indicator for the file referenced by handle. The new position, measured in bytes from the beginning of the file, is obtained by adding offset to the position specified by whence.

Version

PHP 4, 5

Return value

Upon success, returns 0; otherwise, returns -1. Note that seeking past EOF is not considered an error.
