file

Reads entire file into an array

&reftitle.description; ``array``false```file` `string` `filename` `int` `flags` 0 ``resource``null```context`&null;

Reads an entire file into an array.

You can use `file_get_contents` to return the contents of a file as a string.

&reftitle.parameters;

`filename`

- Path to the file.

  &tip.fopen-wrapper;

`flags`

- The optional parameter `flags` can be one, or more, of the following constants:

  `FILE_USE_INCLUDE_PATH`

- Search for the file in the include_path.

`FILE_IGNORE_NEW_LINES`

- Omit newline at the end of each array element

`FILE_SKIP_EMPTY_LINES`

- Skip empty lines

`FILE_NO_DEFAULT_CONTEXT`

- Don't use the default context

`context`

- ¬e.context-support;
&reftitle.returnvalues;

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;.

Each line in the resulting array will include the line ending, unless `FILE_IGNORE_NEW_LINES` is used.

¬e.line-endings;
&reftitle.errors;

Emits an `E_WARNING` level error if the file does not exist.

### `file` example

    <?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";
    }

    // Using the optional flags parameter
    $trimmed = file('somefile.txt', FILE_IGNORE_NEW_LINES | FILE_SKIP_EMPTY_LINES);
    ?>
