How I can get numeric value from a string ?

Here are a few examples. 

val1 = '18,000';    
val2 = '18,000 USD';  
val3 = '18,000 PKR';    
val4 = '18000 PKR';

I need to get only numbers, 18000 only. Nothing else.

    these aren't strings – you need to quote them. – Beat May 29 '13 at 17:14
  • What language? PHP or Javascript? – Jocelyn May 29 '13 at 17:15

try this:

 var num = Number(val1.replace(/[^0-9.]/g, ""));

First you have to replace all commas in the string. Then you can use the JavaScript function parseInt.

var str = "18,000 USD";
str = str.replace(/,/g, "");
var num = parseInt(str, 10);
alert(num);

Now, if you want decimal places, you can use parseFloat.

var str2 = "18,000.50 USD";
str2 = str2.replace(/,/g, "");
var num2 = parseFloat(str2, 10);
alert(num2);

Assuming you make corrections to your code, you should be able to convert them to their real values with this

var val1 = "18,000";
var val2 = "18,000 USD";
var val3 = "18,000 PKR";
var val4 = "18000 PKR";

[val1, val2, val3, val4].map(function (n) { 
  return Number(n.replace(/[^\d]+/gi, '')) 
});

That should give you an array of values like this:

[ 18000,
  18000,
  18000,
  18000 ]

For PHP you could do this:

    $val1 = "18,000";
    $val2 = "18,000 USD";
    $val3 = "18,000 PKR";
    $val4 = "18000 PKR";

    function map ($n) {
        $n = preg_replace("%[^\d]+%mi", '', $n);
        return $n;
    }

    $vals = array_map(map, array($val1, $val2, $val3, $val4));

$vals will hold the real values and print_r($vals); should yield:

    Array
    (
        [0] => 18000
        [1] => 18000
        [2] => 18000
        [3] => 18000
    )
