Function: is

Function : is_empty

This function tests if a value is empty. This can be an array or trimmed string. By trimming strings before testing, it acts as a proof against empty spaces. The function is also capable of regarding non-empty values as empty values. Examples are shown below:

Syntax

  is_empty($testval, $includes)

  
  $testval: value to be tested
  $includes: values to be regarded as empty values

Sample 1

  vdump(is_empty('10')); //false

The value above is not empty value, hence, false is returned

Sample 2

  vdump(is_empty('')); //true

The string value above is empty, hence, true is returned

Sample 3

  vdump(is_empty(' ')); //true

The string value above contains only empty spaces, hence, true is returned

Sample 4

  vdump(is_empty([])); //true

The array value above is empty, hence, true is returned

Sample 5

  vdump(is_empty('10', [5, 10, 15])); //true

The value above exist in the empty values array list, hence, true is returned

Sample 6

  vdump(is_empty('10', [2, 4, 6])); //false

The value above does not exist in the empty values array list, hence, false is returned
