Identical to readfile(), except that file() returns the file in an array. Each element of the array corresponds to a line in the file, with the newline still attached.
Note: Each line in the resulting array will include the line ending, so you still need to use trim() if you do not want the line ending present.
Note: If you are having problems with PHP not recognizing the line endings when reading files either on or created by a Macintosh computer, you might want to enable the auto_detect_line_endings run-time configuration option.
You can use the optional second parameter and set it to "1", if you want to search for the file in the include_path, too.
<?php
// get a web page into an array and print it out
$fcontents = file ('http://www.example.com/');
while (list ($line_num, $line) = each ($fcontents)) {
echo "<b>Line $line_num:</b>; ", htmlspecialchars ($line), "<br>\n";
}
// get a web page into a string
$fcontents = implode ('', file ('http://www.example.com/'));
?> |
Note: As of PHP 4.3.0 you can use file_get_contents() to return the contents of a file as a string in a binary safe manner.
| Warning |
This function is not (yet) binary safe! |
Tip: You can use a URL as a filename with this function if the fopen wrappers have been enabled. See fopen() for more details on how to specify the filename and Appendix I for a list of supported URL protocols.
See also readfile(), fopen(), fsockopen(), and popen().
