fgets

Description

Gets a line from file pointer.

Parameters

stream

All

length

Reading ends when length - 1 bytes have been read, or a newline (which is included in the return value), or an EOF (whichever comes first). If no length is specified, it will keep reading from the stream until it reaches the end of the line.

Return Values

Returns a string of up to length - 1 bytes read from the file pointed to by stream. If there is no more data to read in the file pointer, then false is returned.

If an error occurs, false is returned.

Examples

Reading a file line by line

<?php

$fp = @fopen("/tmp/inputfile.txt", "r");

if ($fp) {
    while (($buffer = fgets($fp, 4096)) !== false) {
        echo $buffer, PHP_EOL;
    }

    if (!feof($fp)) {
        echo "Error: unexpected fgets() fail\n";
    }

    fclose($fp);
}

?>
