[nycphp-talk] convert str array to int ???

Sorry for the miss info.  What I meant to say is that, there is only one 
elementary type.  This is always text (String if you will).  Since I used to 
do C/C++ with CGI.  String is what I call it.  Also the C/C++ does not have 
String or Array Type.  We just used char type. :-)  Maybe it is just a 
little too much detail (Maybe even useless in term of programming in PHP)

"anything from a form is always a string"

That's not totally true...

Try this out:

<?php

function displayArray($array) {

	echo '<table width="500" border="1" cellspacing="1" cellpadding="3">';

	foreach ($array as $key => $value) {

		echo '<tr><td width="25%"><b>' . $key . '</b></td><td width="75%">' .
$value . '</td></tr>';

	}

	echo '</table>';

	return;

}

	if ($_POST['action'] == 'process') {

		displayArray($_POST);

	} else {

?>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

<html>
<head>
	<title>Untitled</title>
</head>

<body>

<form method="post">

<input type="hidden" name="action" value="process">

<input type="text" name="name[first_name]" size="20">

<input type="submit">

</form>

</body>
</html>

<?php

	}

?>

The variable 'name' in the form is now an array.

First, anything from a form is always a string, because there isn't anything
that is past to your php script that says it is any other type.  Second, you
can use "array_merge.

Hi,
i have a script which works with integers. i am taking the inputs from a
form and now it defaults to string. a var_dump gives :

INPUTS :
array(2) {
    [0]=>
    array(2) {
      [0]=>
      string(1) "0"
      [1]=>
      string(1) "1"
    }
    [1]=>
    array(2) {
      [0]=>
      string(1) "1"
      [1]=>
      string(1) "1"
    }
}

but i need the values to be ints....

i tried :

foreach ($pieces as $k => $v) {
   $$k = $v;
   echo $k ."=". $v ."<br>";
//var_dump ($v);
   $cast = is_array ($v);
   if ($cast) {
    foreach ($v as $key => $val) {
     $$key = $val;
     echo $key ."=". $val ."<br>";

     $chk = is_int($val);
     echo "variable type : $chk <br>";
     if (!$chk) settype ($val,"integer");
    }
   }
}

but still i am not able to type juggle. i have missed something but i am
unable to find out what. can someone plz identify what it is?
is there a better way, i am not sure i am coding in the right way...

also, i have two arrays, i want to merge them as :
new[0] = array1[0], array2[0], array2[1]
new[1] = array1[1], array2[1], array2[1]

how to do this, i am again not getting the results like expected.

Thz
Tracy
