Invalid argument supplied for foreach()

Here is what I have...

An array - $result_array

Code:

---

Array
(
    Array
    (
        [name] => Phil
        [email] => [email protected]
        [company] => VNL
    )
    Array
    (
        [name] => Phil
        [email] => [email protected]
        [company] => Norm's World
    )
    Array
    (
        [name] => Ppeter
        [email] => [email protected]
        [company] => Norm's World
    )
    Array
    (
        [name] => Norm
        [email] => [email protected]
        [company] => Norm's World
    )
    Array
    (
        [name] => Webby Guy
        [email] => [email protected]
        [company] => VNI
    )
)

---

..and then I have a for and foreach which write the contents of each array within the $result_array array to a table:

PHP Code:

---

for ($c = 0; $c <= $result_array; $c++) {
    echo "    <tr>\n";
    foreach ($result_array[$c] as $data){
        echo "      <td>$data</td>\n";
    }
    echo "    </tr>\n";
} 


---

The table gets written out fine, but I get an infinite loop that gives me this error:

Warning: Invalid argument supplied for foreach() in <snip>loop.php on line 205

I figure I'm probably missing something obvious. Any help appreciated,

Thanks, Norm

I've never heard that it's valid to compare an integer to an array, neither is there any indication in the PHP docs that it is so. This is not perl, after all.
Even if it were, even if it yielded the number of elements in the array, using <= would be invalid and would attempt to access one element past the end.
Furthermore, because array entries can have string indices, you're not even guaranteed to get anything by looping a numeric index.

There are only two reliable ways of looping over complete arrays, and those are foreach and while(each) loops. There's no reason not to use them either.

Code:

---

foreach($result_array as $subarray) {
    echo "    <tr>\n";
    foreach ($subarray as $data){
        echo "      <td>$data</td>\n";
    }
    echo "    </tr>\n";
}

Umm... maybe because $result_array is not a number?? You need to find out how many elements are in the array and only loop to that many. I would suggest using the count() function to get the number of elements in the array, but keep in mind, you'll have to use just the < operator as the count will be starting from 1, not zero.

And it just occurred to me that your current code may be correct, except for what I just mentioned. Make it < rather than <= and see if that works.

Yep.

for ($c = 0; $c < sizeof($result_array); $c++)

Thanks
