Example 1:# Opening a file for reading.
<?
$file = file("file.txt");
$j = count($file);
for($i=0; $i<$j; $i++) {
echo "$file[$i]<br>";
}
?>
Example 2:# Opening a file for reading.
<?
$my_file = "file.txt";
$fp = fopen($my_file, 'r');
$buffer = fread($fp, filesize($my_file));
echo $buffer;
fclose($fp);
?>
Example 3:# Opening a file for writing.
<?
$my_file = "/path/to/file.txt";
$message = "This is a line of text"."\n";
$fp = fopen ($my_file, 'w');
fwrite ($fp, $message);
fclose ($fp); }
?>
Example 4:# Opening a file for appending.
<?
$my_file = "/path/to/file.txt";
$message = "This is a line of text"."\n";
$fp = fopen ($my_file, 'a');
fwrite ($fp, $message);
fclose ($fp);
?>
