Array to string conversion error - why?

Keiron Waites

I get the following error:

Notice: Array to string conversion in C:\Documents and
Settings\ShepMode\Desktop\Websites\ShareMonkey.net \Web\join.php on line 11
in this code:

$input = array(array("First
Name",$_POST['firstname']),array("Surname"=>$_POST['surname']),array("Compan
y Name"=>$_POST['company_name']),
array("Website / Application
URL"=>$_POST['url']),array("Email
Address"=>$_POST['email']),array("Username"=>$_POST['username']),
array("Password"=>$_POST['password']));

(line 11) if (substr_count($value,"@") != 1) {
$error_message .= "The email address you have
entered is invalid.<br>";
}

Why does substr_count($value,"@") cause this notice? And since it is not an
error as such, how do I rectify it without modifying php.ini?

Thanks,

Keiron

Because $value is an array? Hard to say without seeing where it's assigned...

Don't hide this warning, since you've probably now counting the number of @
characters in the string 'Array', which isn't what you want...

Crap sorry, this: foreach ($input as $name => $value) { assigns the
$value.

So:

$input = array(array("First
Name",$_POST['firstname']),array("Surname"=>$_POST['surname']),array("Compan
y Name"=>$_POST['company_name']),
array("Website / Application
URL"=>$_POST['url']),array("Email
Address"=>$_POST['email']),array("Username"=>$_POST['username']),
array("Password"=>$_POST['password']));
foreach ($input as $name => $value) {
(line 11) if (substr_count($value,"@") != 1) {
$error_message .= "The email address you have
entered is invalid.<br>";
}
}

I don't want to hide the error, I want to fix the code :) Is there something
about the foreach that I don't understand?

$input = array(array("First
Name",$_POST['firstname']),array("Surname"=>$_POST['surname']),array("Compan
y Name"=>$_POST['company_name']),
array("Website / Application

foreach ($input as $name => $value) {
So each $value is an array.
(line 11) if (substr_count($value,"@") != 1) {
Running substr_count on an array doesn't make sense; the array gets turned
into the string 'Array' and a warning output.

Not sure why you've got a load of single-element arrays inside the outer
array.

Did you want something more like:

$input = array(
"First Name" => $_POST['firstname'],
"Surname" => $_POST['surname'],
"Company Name" => $_POST['company_name'],
"Website / Application URL " => $_POST['url'],
"Email Address" => $_POST['email'],
"Username" => $_POST['username'],
"Password" => $_POST['password'],
);
