fgets -- Gets line from file pointer


string fgets (int fp, int length)

Returns a string of up to length - 1 bytes read from the file pointed to by fp. Reading ends when length - 1 bytes have been read, on a newline (which is included in the return value), or on EOF (whichever comes first).

If an error occurs, returns false.

Common Pitfalls:

People used to the 'C' semantics of fgets should note the difference in how EOF is returned.

The file pointer must be valid, and must point to a file successfully opened by fopen(), popen(), or fsockopen().

A simple example follows:

Example 1. Reading a file line by line

$fd = fopen ("/tmp/inputfile.txt", "r");
while (!feof ($fd)) {
    $buffer = fgets($fd, 4096);
    echo $buffer;
fclose ($fd);
