I am new to codeigniter and PHP. I have a doubt in PHP. My code is something like this.

public function Test()
    {
        $qryResult = $this->GenerateRnd();
        
        if($qryResult == 1)
        {
            echo "True";
            return;
        }

    } 

GenerateRnd will Generate random string and check in DB and return the count. I want help in function test(). I want to generate string again if $qryResult == 1. Otherwise continue process. Wethere the present code will enough or any changes need. Please help me.

You have missing GenerateRnd() function declaration!

I didn’t post GenerateRnd() function. I just want to know return will execute $qryResult = $this->GenerateRnd() or not.

instead of

if($qryResult == 1)
{
  echo "True";
  return;
} 

do

if($qryResult)
{
   echo "True";
   return $qryResult;
} 

the echo “True”; is not really needed but i am assuming you want to actually print “True” on the screen
