Output (echo/print) everything from a PHP Array

Question

Is it possible to echo or print the entire contents of an array without specifying which part of the array?

The scenario: I am trying to echo everything from:

<

Answer 1

You can use print_r to get human-readable output.

See http://www.php.net/print_r

Answer 2

You can use print_r to get human-readable output. But to display it as text we add "echo '';"

echo ''; print_r($row);

Answer 3

I think you are looking for print_r which will print out the array as text. You can't control the formatting though, it's more for debugging. If you want cool formatting you'll need to do it manually.

Answer 4

Similar to karim's, but with print_r which has a much small output and I find is usually all you need:

function PrintR($var) {
    echo '<pre>';
    print_r($var);
    echo '</pre>';
}

Answer 5

This is a little function I use all the time its handy if you are debugging arrays. Its pretty much the same thing Darryl and Karim posted. I just added a parameter title so you have some debug info as what array you are printing. it also checks if you have supplied it with a valid array and lets you know if you didn't.

function print_array($title,$array){

        if(is_array($array)){

            echo $title."<br/>".
            "||---------------------------------||<br/>".
            "<pre>";
            print_r($array); 
            echo "</pre>".
            "END ".$title."<br/>".
            "||---------------------------------||<br/>";

        }else{
             echo $title." is not an array.";
        }
}

Basic usage:

//your array
$array = array('cat','dog','bird','mouse','fish','gerbil');
//usage
print_array("PETS", $array);

Results:

PETS
||---------------------------------||

Array
(
    [0] => cat
    [1] => dog
    [2] => bird
    [3] => mouse
    [4] => fish
    [5] => gerbil
)

END PETS

Answer 6

For nice & readable results, use this:

function printVar($var) {
    echo '<pre>';
    var_dump($var); 
    echo '</pre>';
}

The above function will preserve the original formatting, making it (more)readable in a web browser.
