How to suppress any output from a function in PHP

Answer 1

function example($i) {
  echo "example() function: " . $i . "\n";
  
  return true;
}

$rv  = false;
$rv = example(3524); // output "example() function: 3524"
echo "A rv = " . $rv . "\n"; // return true;

$rv  = false;
// ob = output buffering
ob_start();
$rv = example(86903); // get return value without output
echo "B1 rv = " . $rv . "\n";
ob_end_clean();
echo "B2 rv = " . $rv . "\n"; // return true;



/*
run:

example() function: 3524
A rv = 1
B2 rv = 1
