foreach : Invalid argument supplied

[williamZanelli]

Hi guys,

 

Just wondering if you could tell me whats wrong with the following array

 

$array2d= array(

    5  => array(
    'fname'  =>  'Smith',
    'sname'  => 'smith'
    ),

);

 

Its had me all day, when I run it inside a foreach, it throws the following warning,

 

Warning: Invalid argument supplied for foreach()  - followed by the line number.

 

Thanks for your thoughts

Can we see all the relevant code?  If you put that in a foreach it will work.

With the array is not wrong, with your code proably is.

Hi guys,

 

Thanks for the prompt responses.

 

The code I have is cumbersome, so I decided to keep it simple.

 

The foreach is like,

 

foreach($array2d as $key => $val) {
                if($data[$key] != '') {
                    $sql = "......"
//loads of business logic etc.

 

The error is thrown at line foreach.

 

Thanks for your thoughts

You should var_dump the array variable to make sure it is correctly populated.

do you do something with $array2d sometime between where you assign it and run that foreach?  Invalid argument means it is not an array. ..

Thanks for this guys.

 

How do I do a var dump?

You can do:

 

print_r($array2d);
//or
var_dump($array2d);

 

Like CV said, you must be changing your array between the codes you've posted.  Please post all the code from your first except to the second.
