# file

(PHP 3, PHP 4 , PHP 5)

file -- Reads entire file into an array

## Description

array file ( string filename [, int use_include_path [, resource context]] )

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. Upon failure, file() returns `FALSE`.

You can use the optional use_include_path parameter and set it to "1", if you want to search for the file in the include_path, too.

`<?php
// Get a file into an array. In this example we'll go through HTTP to get
// the HTML source of a URL.
$lines = file('http://www.example.com/');
// Loop through our array, show HTML source as HTML source; and line numbers too.
foreach ($lines as $line_num => $line) {
echo "Line #<b>{$line_num}</b> : " . htmlspecialchars($line) . "<br />\n";
}
// Another example, let's get a web page into a string. See also file_get_contents().
$html = implode('', file('http://www.example.com/'));
?>`

> Vihje: T�m�n funktion kanssa voit k�ytt�� my�s URLia tiedostonimen sijaan jos "fopen wrappers" on kytketty p��lle. Katso funktiosta fopen() lis�tietoa tuetuista URL-protokollista ja siit� kuinka tiedoston nimi m��ritell��n Liite L.

> Huomaa: Each line in the resulting array will include the line ending, so you still need to use rtrim() if you do not want the line ending present.

> Huomaa: 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.

> Huomaa: As of PHP 4.3.0 you can use file_get_contents() to return the contents of a file as a string.

> In PHP 4.3.0 file() became binary safe.

> Huomaa: Context support was added with PHP 5.0.0.

Varoitus
Some non-standard compliant webservers, such as IIS, send data in a way that causes PHP to raise warnings. When working with such servers you should lower your error_reporting level not to include warnings.

See also readfile(), fopen(), fsockopen(), popen(), file_get_contents(), and include().
