First, don't use "help pls!" as a subject. That will get ignored by many
readers.
Secondly, you *REALLY* should put this stuff into a DATABASE, not a file.
Honest. It's going to be much *EASIER* if you do.
Here's the PHP for what you think you want, but you really don't:
<?php
if (isset($rates)){
$file = fopen('rate.php', 'w') or die("Unable to record new rate
information. Sorry!");
while (list($country, $rate) = each($rates)){
$line = "'$country' => '$rate'";
$charcount = fputs($file, $line);
if ($charcount != strlen($line)){
echo "Only wrote $charcount out of ", strlen($line), "
characters!<BR>\n";
}
}
}
?>
<FORM ACTION=<?=$PHP_SELF?> METHOD=POST>
<?php
$rates = file('rate.php') or die("Unable to look up rate information.
Sorry!");
while (list(,$line) = each($rates)){
$parts = explode('=>', $line);
$country = trim($parts[0]);
$rate = trim($parts[1]);
$country = substr($country, 1, -1); # Strip off apostrophes.
echo "$country <INPUT NAME=rates[$country] VALUE=$rate><BR>\n";
}
?>
<INPUT TYPE=SUBMIT>
</FORM>
