title: Why php print_r($array) will not print the spaces in a string
body: <pre><code>$myArray = array();
  
  array_push($myArray, "'     a'");
  
  use Framework\ArrayMethods as ArrayMethods;
  print_r(($myArray));
  print_r(ArrayMethods::lengtOfElements($myArray));
  </code></pre>
  
  <p>The output will be:</p>
  
  <pre><code>Array ( [0] =&gt; ' a' ) Array ( [0] =&gt; 8 ) 
  </code></pre>
  
  <p>So there is only one whitespace before a in the printed string, but the strelen returns 8?
  How to make it print '     a' ? </p>
