If you zip up all your files along with an sql dump of your db and anything else needed to run your code I will look at it.

[HTML Form data to CSV file using PHP]

Close. You need to remove the hardcoded $_POST values for your form to work. Also dont use $_SERVER['PHP_SELF'], it is vulnerable to SQL Injection. Use $_SERVER['script_name']

Run this. If it doesn't work you may have a file permission issue.

$_POST['fname'] = 'Sam';
$_POST['lname'] = 'Smith';
$_POST['sex']   = 'M';

$list = array(
    array(
        $_POST['fname'],
        $_POST['lname'],
        $_POST['sex']
    )
);

$fp = fopen('test.csv', 'a');

foreach ($list as $fields)
    {
    fputcsv($fp, $fields);
    }
fclose($fp);

[Help with arrays.]

Speaking of "Skinning a Cat", lets all head on over here for some fun.

[Skinning a cat (Or how many ways to output "Hello World!")]

We all know in PHP there are many ways to come up with the same exact result. Just for fun, lets see how many ways you can come up with to output the standard Hello World!. I did this on another forum awhile back and there are many. I will start off with the two most basic ways;

 

 

echo "Hello, World!";

 

print "Hello, World!";

[Help with arrays.]

 

Well, if we're just showing different ways to skin a cat:

$fun = array(
 'First Word' => 'Programming',
 'Second Word' => 'in',
 'Third Word' => 'PHP',
 'Fourth Word' => 'is',
 'Fifth Word' => 'fun!',
 'Programming in PHP is fun!'
);
 
$fullSentence = array_pop($fun);
foreach($fun as $key => $val) 
{
    echo "$key, $val<br />";
}
echo $fullSentence;

 

 

Interesting take, although it does require that you know that the last element is the one without a key.

[Help with arrays.]

Just for giggles:

$fun = array(
 'First Word' => 'Programming',
 'Second Word' => 'in',
 'Third Word' => 'PHP',
 'Fourth Word' => 'is',
 'Fifth Word' => 'fun!',
 'Programming in PHP is fun!'
);

foreach($fun as $key => $val) 
{
    if ($val != end(array_values($fun))) {
        echo "$key, ";
    }

    echo "$val<br />";
}
