(PHP 3, PHP 4 >= 4.0.0) file -- Reads entire file into an array Descriptionarray file ( string filename [, int use_include_path])
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.
Huomaa:
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.
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.
Huomaa:
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.
| Varoitus | Tämä funktio ei (vielä)
osaa käsitellä binäärimuotoista dataa! (esim. kuvia) |
Vihje: Tämän funktion kanssa voit
käyttää myös URLia tiedostonimen sijaan jos "fopen wrappers" on kytketty
päälle. Katso myös fopen().
See also readfile(),
fopen(), fsockopen(), and
popen().

The file() function doesn't recognize Macintosh line breaks as delimiters.
You'll need to convert them to UNIX newlines characters before using this
function.

It appears that the file() function causes file access problems for perl
cgi scripts accessing the same files. I am using Perl v5.6.0 in linux
with PHP/4.0.4pl1. After running a php app using the file() function, any
perl cgi trying to access the same file randomly dies returning an
internal server error: premature end of script headers.
The simple
fix is to use fopen(), fgets() and fclose() instead of file().

Here is a simple way to find the size of an html page that is a url, not a
file:
$myurl = "http://www.fuzzygroup.com/";
$content_array
= file($myurl);
$content = implode("",
$content_array);
$mysize = strlen($content);
print $mysize;

file() has a strange behaviour when reading file with both \n and \r as
line delimitator (DOS files), since it will return an array with every
single line but with just a \n in the end. It seems like \r just
disappears.
This is happening with PHP 4.0.4 for OS/2. Don't know
about the Windows version.

You can always directly insert a carriage return and line
feed:
chr(13).chr(10)
Seems to work fine for me. Remember to
use them together as some text readers wont recognise these separately.
e.g. chr(13) (carriage return) in some cases will display an invalid
character at the point where you wanted a new line. Adding chr(10) solves
this.
I find it handy to make it a global var.
I know it's
small but hopefully this helps someone who has to develop script for a few
different platforms. It helps me.
Cheers.

Here is a quick snippet that will read in N number of lines of a file, then
print them.
$n=10
$fp =
file(/path/to/your/file);
$i=0
while($i < $n){
echo "$fp[$i]";
$i++;
}
I am using this
right now to display the current progress of the seti@home client working
on my server, instead of displaying the whole thing, which isn't web page
friendly.
Because sometimes short really is sweet...

A binary-safe file() :
function bs_file($filename) {
$fp =
@fopen($filename, "r");
if (!($fp)) {
return
0;
}
while (!feof($fp)) {
$temp .= fread($fp,
4096);
}
$arr = explode("\n", $temp);
return
$arr;
}
But too bad no \n attached :(

need a random line stamp?
useful for humour stories
:-)
<?
$file =
file("/path/to/your/file");
mt_srand ((double)
microtime() * 1000000);
$line = mt_rand(0,count($file));
echo
$file[$line];
?>

If you have formated a text file using spaces, the function file(and
readfile too) deletes them end let only one space between words.
