title: Calculate number of function calls in the same function
body: <p>How to calculate(determine) in php the total number of a function calls but the result of this must be in the same function for which I calculate this number.</p>
  
  <p>Exemple:
  The test() function is called 100 times(this number is variable and so I don't know it from beginning). I want to find this number in the block of function</p>
  
  <pre><code>test();
  
  function test(){
  
  
  
  $no_calls =....
  echo $no_calls;  
  
  }
  </code></pre>
  
  <p>I want the message from echo to be shown only once not to every call of function.</p>
