    with the first function you got 99999999999 unique ids and 1/99999999999 chance for each id to appear.I don't know anything about a viable way to achieve the goal of getting unique ids with only digit except if you use auto increment with left padding like in function 2 to always get the same length for your ids while keeping uniqueness...

    <?php function uniq_digit_id($max=11){//more max is low less you got uniqueness

    $i=0;
    $uniq_digit_id='';
    while($i<$max){
    	$uniq_digit_id .=rand(0,9);
    	$i++;
    }
    

    return $uniq_digit_id;
    

    }

    function uniq_digit_id2($max=11,$data='uniq_digit_id2.txt'){

    
    $i=0;
    $maxnumber='';
    while($i<$max){
    	$maxnumber .='9';
    	$i++;
    }
    if(file_exists($data)){
    	$id=trim(file_get_contents($data));
    	if(strlen($id)==$max){
    		/*you must use only one file per counter otherwise the file will be formatted 
    		to restart counter according to $max arg */
    		if($id==$maxnumber) return false;/*if the max number with the length $max 
    		is reached the response will always be false; so be sure to test the value before use it*/
    	
    		$id++;
    		file_put_contents($data,($id=str_pad($id,$max,'0',STR_PAD_LEFT)));
    		return $id;
    	}else{
    		$id=0;
    		file_put_contents($data,($id=str_pad($id,$max,'0',STR_PAD_LEFT)));
    		return $id;
    	}
    }else{
    	$id=0;
    	file_put_contents($data,($id=str_pad($id,$max,'0',STR_PAD_LEFT)));
    	return $id;
    }
    

    }

    echo '<pre>'; var_dump(uniq_digit_id(),uniq_digit_id(),uniq_digit_id(),uniq_digit_id(),uniq_digit_id()); var_dump(uniq_digit_id2(),uniq_digit_id2(),uniq_digit_id2(),uniq_digit_id2(),uniq_digit_id2()); echo '</pre>';
