help, array values echoed as Array on loop!

I have tried both ways to loop through an array and output the data and verify that the array is an array and I get no erros but I get this value, which should not be so. Here I'm checking if it's an array: if (!is_array($ID_arr)) { # show error if no array echo '$ID_arr is not an array.'; } here I'm counting the keys but it only outputs as 1: $key = count($ID_arr); echo $key; here are two loops that do the same thing and they both output Array: for($i = 0; $i < count($ID_arr); $i++) { echo $ID_arr[$i]; } foreach($ID_arr as $ind_picture) { echo $ind_picture; } Why? If it helps, in order to get the array, the values were taken from a database and exploded from a coma delimited string. $ID_arr[] = explode(',', $pictures); # make db data into array This is the string: 15,16,17,18,19 I want each array element to contain => 15 => 16 => 17 etc... why does it echo as Array? - Victor > www.argilent.com ______________________________________________________________________ Post your free ad now! http://personals.yahoo.ca
