fgets — Gets line from file pointer
Gets a line from file pointer.
파일 포인터는 fopen(), fsockopen()을 통하여 성공적으로 열려, fclose()로 닫지 않은 유효한 파일이여야 합니다.
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 no length is specified, it will keep reading from the stream until it reaches the end of the line.
Note: Until PHP 4.3.0, omitting it would assume 1024 as the line length. If the majority of the lines in the file are all larger than 8KB, it is more resource efficient for your script to specify the maximum line length.
Returns a string of up to length - 1 bytes read from the file pointed to by handle .
If an error occurs, returns FALSE.
| 버전 | 설명 |
|---|---|
| 4.3.0 | fgets() is now binary safe |
| 4.2.0 | The length parameter became optional |
Example #1 Reading a file line by line
<?php
$handle = @fopen("/tmp/inputfile.txt", "r");
if ($handle) {
while (!feof($handle)) {
$buffer = fgets($handle, 4096);
echo $buffer;
}
fclose($handle);
}
?>
Note: PHP가 매킨토시 컴퓨터에서 파일을 읽거나 작성할 때 행의 끝을 판단하지 못하면, auto_detect_line_endings 실행 옵션을 활성화 함으로써 문제가 해결될 수 있습니다.
Note: People used to the 'C' semantics of fgets() should note the difference in how EOF is returned.
