url parsing

Anon

All this code wants to do is print "Array" in the text box I created. What I want is for the code to print a parsed url in the text box. Can anyone tell me what is wrong with this code?

<title>URL_Parser</title>

<form name="frmurlparser" method=post action="url_parser.php">
Enter a URL:
<input name="URL" type="text">
<input name="Parse" type="submit" value="Parse">

</form>

<?php
if ($URL!="") {
$pat=".";
$str=$URL;
$arr=split($pat, $str, 3);
echo ("<textarea name='Parsed' rows=5 cols=40 wrap>$arr</textarea>");

}else {
echo ("<textarea name='Parsed' rows=5 cols=40 wrap></textarea>");

}

?>
</form>

</body>

What 'split' actually does is spliting a string into an array at every pattern found.

If you want to print the contents, element by element, from an array, try this piece of code :

<?php
while(list($index, $value) = each($arr)) {
echo "|$index|$value|<br>\n";
}
?>

And if you want to have it done faster / another way, try this :

<?php
$arr_out = implode('|', $arr);
echo $arr_out;
?>

Hint : Have a look at www.php.net/split to see what the command actually does and perhaps have a look at arrays too.
