<para>
|
|
Identical to <function>readfile</function>, except that
|
|
<function>file</function> returns the file in an array. Each
|
|
element of the array corresponds to a line in the file, with the
|
|
newline still attached.
|
|
</para>
|
|
<note>
|
|
<para>
|
|
Each line in the resulting array will include the line ending, so you
|
|
still need to use <function>trim</function> if you do not want the line
|
|
ending present.
|
|
</para>

You can use the optional second parameter and set it to "1", if
|
|
you want to search for the file in the <link
|
|
linkend="ini.include-path">include_path</link>, too.

As of PHP 4.3.0 you can use <function>file_get_contents</function> to
|
|
return the contents of a file as a string in a binary safe manner.
