How To Echo An Array

It's not like I've never done it before, but for some reason it won't work this time... I'm just returnin an array from a function //Call Function to create the result array $specs

Solution 1:

Print all values of an array

<?phpecho'<pre>';
   print_r($specs);
   // OR var_dump to get variable type (string / int / etc)
   var_dump($specs);
   echo'</pre>';
?>

The echo of the pre tags are for formatting reasons in HTML since the pre tag will show linebreaks (\n) as a visible new line inside of HTML.

As for echoing a single value from an array, all you have to do is refernce the key like you were doing.

echo$specs['length'];

You can make sure the key exists by using the function isset.

if(isset($specs['length'])) {
   echo$specs['length'];
}else{
   echo'Error, Length not found';
}

The functions used in this answer can be found on the PHP.net website var_dump(), print_r() and isset()

Solution 2:

not sure if you want the number of elements of the array :

echo count($specs);

or iterate over your array :

foreach($specsas$key => $value){
    echo"$key : $value<br/>";
}
