help with strlen function

[gammaman]

Why does this function not work

 

<?php

function string($string)
{
    $x=strlen($string);

    

    if($x>=6){
      return true;
    }else{
      return false;
    }
}

$words="This is a String";
string($words);
?>

What is not working?

 

How do you know what the return value is?  Are you echoing it?

Is it coming out as "false", thefore not working?

[soycharliente]

string may be a reserved word in PHP. Try naming it something different.

 

Also, what exactly isn't working? You're not echoing anything to the screen.

 

<?php

function checkLen($input)
{
if (strlen($input) >= 6)
{
	return TRUE;
}
else
{
	return FALSE;
}
}

$words = "This is a string.";
echo checkLen($words);
?>
