trying to run function just once

If you are not inside a class context, you can use static variables instead.

PHP Code:

static $hasRun;

if ($hasRun !== true)
{
    $hasRun = true;

    // run your function here
}

I tried this. I tried placing $hasRun above class Configure extends CI_Controller but I get undefined variable. Then I placed it between 
class Configure extends CI_Controller
{
    static $hasRun;    <<<<<<<<here
    public function __construct()

And i still get undefined variable.
I put the if ($hasRun !== true) in the __construct()

Its amazing topic


function foo()
{
    static $foo_called = false;
    if (!$foo_called) {
        $foo_called = true;
        // etc.
    }
}

The problem is that foo runs each time.

@richb201 ,

I have not used static before and decided to give it a try... discovered it ONLY works on Class Methods(...).

The following KLUDGE should work which I have tried in:

CI4 -> app/Common.php -> function fred(...)

Code:

//==================================================
function fred($val='Nothing set???', mixed $title='NO TITLE')
: string
{
  if( defined('CALL_ONCE_ONLY') ) :
    echo '<br> PREMATURE FUNCTION RETURN AND NOT USED';
    return '';
  endif;
  define('CALL_ONCE_ONLY', 'pretty please');


  $results = print_r($val, TRUE);

  echo $tmp = <<< ____EOT
    <div> <br> </div>
      <dl class="w88 mga fss bgl bd1 p42" >
        <dt> <b> $title </b> ==> </dt>
        <dd>
          <pre class="tal wrp bga">
            <b> $title </b> ==>
            <br>           
            $results
          </pre>
        </dd> 
      </dl> 
____EOT;

  return $result=(string) '';
}//

Following your lead I stuck this in the bottom of _init()
if(defined('RUNONCE')) {
}
else {
    $this->get_from_locker();  //bring down this guy's images
    define ('RUNONCE','YES');
}

Unfortunately it keeps running get_from_locker() each time.
