open read then write

[weazy]

i want to open a file, say config.php to read from, i am using openclose.php to do the opening and reading.

in config.php there are variables set like:
<?

$var1 = 'php coding is fun';

$var2 = 'i like open source';

$var3 = 'string3';

<............bunch of other crap.........................>

?>

how do i read those variables and then write them to openclose.php?

so far i have:

<?

$fh = fopen('config.php', 'r');
if (!$fh) {
echo "Couldn't open config.php, make sure you are in the correct directory.";
} else {
echo "Opened config.php, begin writing shortly.<br><br>";

<..........need some direction here............>

if (!fclose($fh)) {

echo  "Did not properly close config.php.";

} else {
echo "Closed config.php for reading.";
}
}

?>

If you have a possibility for storing data outside your webdir you could use a text file to store the settings.
Its much easier if you can do it like this:

php coding is funⁱ like open source^string3

in a textfile, without all the tags.
You can then explode() the row into an array:

function file_get_contents($filename, $use_include_path = 0) {
$fd = fopen ($filename, "rb", $use_include_path);
$contents = fread($fd, filesize($filename));
fclose($fd);
return $contents;
}

$atext = file_get_contents("../variables.txt");
if (!$atext) { 
echo "Couldn't open variables.txt, make sure you are in the correct directory."; 
} else { 
$vArr = explode("^", $atext);
$myVar1 = $vArr[0];
$myVar2 = $vArr[1];
$myVar3 = $vArr[2];
fclose($atext));
} 

echo $myVar1."<br>";
echo $myVar2."<br>";
echo $myVar3."<br>";

But I'm suddenly wondering here:
Do you just want to echo the values, or do you actually want to write them to a file??

If you just want access to them, you can use the construct
include("config.php");
and all the values there will be accessible in openclose.php

id just go with mogsters suggestion if you can. However if you are stuck with text file encoding...

have you looked into the [man]parse_ini[/man] function

i think the include statement is teh way to go. good idea. but the filehandling tip is also useful. thanks to both for the tips.
