The empty() function will return true if the POST or GET arrays are empty. There is no need to loop over the values like this.</p> Tue, 21 Dec 2010 22:10:39 UTC https://snipplr.com/view/39904/post-or-get-data-empty-check https://snipplr.com/view/39904/post-or-get-data-empty-check <p>I don't directly loop POST or GET. I use like this. $val1 = $_POST['val1']; $val2 = $_POST['val2']; $val4 = $_POST['val3']; $arr = array($val1, $val2, $val3); if(check_empty($arr) === false) { // codes here } Any advice?</p> Thu, 23 Dec 2010 17:34:48 UTC https://snipplr.com/view/39904/post-or-get-data-empty-check https://snipplr.com/view/39904/post-or-get-data-empty-check <p>Okay, but I am not quite sure in what situation a function like that would be useful. If you want to know if an array is empty simply use: if (empty($array)) { echo "The array is empty"; } If you want to know if an array is NOT empty. ("!" means "not" and basically flips boolean values on their heads, so that false becomes true and vice versa): if ( ! empty($array)) { echo "The array is NOT empty"; } if you want to know if an array CONTAINS one or more empty values. if (in_array(null, $arr)) { echo 'Array contains one or more empty values'; } In PHP if a value can be thought of as empty it is considered to be of the type null: 0 (zero), false (boolean), "" (empty string), array() (empty array), 0.0 (empty decimal number), and so on, are all considered to be null. Be careful, though, to not use === in cases like this, because === also checks for the variable type and then the aforementioned values will not equal null. Also, you should take a look at PHP's [array functions](http://www.php.net/manual/en/ref.array.php "PHP array functions"). It is rare that you need to define your own functions for use with arrays. Anyways, so you can do something like this: $arr = array($POST['val1'],$POST['val2'],$_POST['val3']); if (in_array(null, $arr)) { echo 'Array contains one or more empty values'; }</p> Sun, 02 Jan 2011 07:39:37 UTC https://snipplr.com/view/39904/post-or-get-data-empty-check https://snipplr.com/view/39904/post-or-get-data-empty-check <p>Unlock endless possibilities with our vast collection of software licenses.
