PHP: Adapt number ID to words

What do I need to do to convert the number only if all the number matches?

At the moment, it’s converting to each number. (I’ve tried to do a lot and I didn’t succeed) I would like to know if have any way of adapting to only show the word if the number “is complete”, otherwise show the word “Doesn’t contain a name record”.

Example: When I try to use the number 1987, the output its: Name1 Name9 Name8 Name7, and I want to be only one word: Name1987.

function numberTowords($num)
{

    $ones = array(
        0 => "Name0",
        1 => "Name1",
        2 => "Name2",
        3 => "Name3",
        4 => "Name4",
        5 => "Name5",
        6 => "Name6",
        7 => "Name7",
        8 => "Name8",
        9 => "Name9",
        10 => "Name10",
        11 => "Name11",
        12 => "Name12",
        13 => "Name13",
        14 => "Name14",
        15 => "Name15",
        16 => "Name16",
        17 => "Name17",
        18 => "Name18",
        19 => "Name19",
        1987 => "Name1987",
        2398 => "Name2398",
    );

    $num = number_format($num, 2, ".", ",");
    $num_arr = explode(".", $num);
    $wholenum = $num_arr[0];
    $decnum = $num_arr[1];
    $whole_arr = array_reverse(explode(",", $wholenum));
    krsort($whole_arr, 1);
    $rettxt = "";
    foreach ($whole_arr as $key => $i) {
        while (substr($i, 0, 1) == "0")
            $i = substr($i, 1, 5);
        if ($i < 20) {
            /* echo "getting:".$i; */
            $rettxt .= $ones[$i];
        } elseif ($i < 100) {
            if (substr($i, 1, 1) != "0") $rettxt .= " " . $ones[substr($i, 1, 1)];
        } else {
            if (substr($i, 0, 1) != "0") $rettxt .= $ones[substr($i, 0, 1)];
            if (substr($i, 2, 1) != "0") $rettxt .= " " . $ones[substr($i, 2, 1)];
        }
        if ($key > 0) {
            $rettxt .= " ";
        }
    }
    if ($decnum > 0) {
        $rettxt .= " and ";
        if ($decnum < 20) {
            $rettxt .= $ones[$decnum];
        } elseif ($decnum < 100) {
            $rettxt .= " " . $ones[substr($decnum, 1, 1)];
        }
    }
    return $rettxt;
}

Answer

only show the word if the number “is complete”, otherwise show the word “Doesn’t contain a name record”.
Example: … number 1987 I want (output) to be only one word: Name1987.

If this is all you need – piece of cake:

<!-- this is only a tool for easy test -->
<form><input name="nr"><input type="submit"></form>

<?php
$pattern = array_merge(range(0,19),[1987,2398]);
$nr = $_GET[nr];

echo    in_array($nr,$pattern) ? "Name$nr" : "Doesn't contain a name record";

array_merge() joins arrays, range() is kind of array, in_array() checks if a value exists in an array

---

more flexible – for cases you omitted in your question

$pattern = [0=>'my name is Zero',
        1=>'I am the ONE',
        12345=>'this is a number',
        '12345'=>'this is a string',
        '7x24'=>'all time shift',
        999=>'almost thousand',
        12=>'call me a dozen'];

echo    array_key_exists($nr,$pattern) ? $pattern[$nr] : "Doesn't contain a name record";

// if you don't like shorthand - different notation:

if(array_key_exists($nr,$pattern)){ echo $pattern[$nr];}
else{   echo "Doesn't contain a name record";}

array_key_exists()

Arrays are fast and nice in use. Built-in functions are optimised and that makes them much better than step-by-step manipulations. Debugging a few lines of code is easy, debugging plenty lines of particular manipulations is a nightmare. For most cases in php the only concern is to find the name of built-in function which do it all at once.

I didn’t want to limit the numbers (…) want to add more than 200 ids

I didn’t limit anything, and it is not that much, even as associative array it wouldn’t be big array

more complex – it’s time to organise the code structure

function name($x,$arr){
    if(in_array($x,range(130,150))){        $name = 'from 130 to 150';}     //or (($x >= 130) && ($x <= 150)), or ... etc
    else if(in_array($x,range(100,200))){   $name = 'from 100 to 200';}
    else if(array_key_exists($x,$arr)){     $name = $arr[$x];}
    else{                                   $name = 'pass';}
    $z = ($x[0] == 0) ? 'leading zero' : '&lowast;';        //or if-else instead of Elvis, (substr($x,0,1) == 0) ...
    return($z.' '.$name);}

echo    '<p>'.name($nr,$pattern).'</p>';

In the name() function, sequence is important for the sub-ranges.

ternary operator a.k.a. Elvis
filter_var() if you like it
