function generate_random_password($length){
	$length=10;
	$password='';
	while($length>0){
		$password.=chr(mt_rand(33, 125));
		$length--;
	}
	return $password;
	}

echo generate_random_password(10);

it will generate password for 33 , 125 ASCII value .
it will give you random password with more secure and in less code
you can also put mt_rand(0,100) . you can check ASCII table to predict how it make password .

below function provide secure password and difficult to guess because it give you mix of A-Z , a-z , 0-9 , special character


	function generate_random_password($length = 10)
	{
		$alphabets = range('A','Z');
		$Smallalphabets = range('a','z');    
		$numbers = range('0','9');
		$additional_characters = array('_','.'); 
		$final_array = array_merge($alphabets,$Smallalphabets,$numbers,$additional_characters);
		
		$password = '';
		
		while($length--)
		{
			$key = array_rand($final_array);
			$password .= $final_array[$key];
		}
		return $password;
	}

call it to generate random password


$random_secure_password=generate_random_password(9);

you can make more complex by adding more special character like below code.
i add more special character at $additional_characters


      function generate_random_password($length = 10)
	{
		$alphabets = range('A','Z');
		$Smallalphabets = range('a','z');    
		$numbers = range('0','9');
		$additional_characters = array('_','.',"#","$","%","@","!"); 
 		$final_array = array_merge($alphabets,$Smallalphabets,$numbers,$additional_characters);
		
		$password = '';
		
		while($length--)
		{
			$key = array_rand($final_array);
			$password .= $final_array[$key];
		}
		return $password;
	}

it make good random generated password which more secure and not easy to guess
