Remove decimal point e.g. 99.99 = 9999

I am trying to find a way to remove a decimal point from a number.

E.g.

1.11 would equal 111

9.99 would equal 999

1.1111 would equal 11111

Can't seem to find the function I need to do this. I have been googling to find this function but no luck.

I have tried these functions but it is not what I am looking for: 

floor(99.99) = 99
round(99.99) = 100
number_format(99.99) = 100

We can use explode:

$num = 99.999;
$final = '';
$segments = explode($num, '.');
foreach ($segments as $segment){
  $final .= $segment;
}
echo $final;

Checkout this demo: http://codepad.org/DMiFNYfB

Generalizing the solution for any local settings variations we can use preg_split as follows:

  $num = 99.999;
    $final = '';
    $pat = "/[^a-zA-Z0-9]/";
    $segments = preg_split($pat, $num);
    foreach ($segments as $segment){
      $final .= $segment;
    }
    echo $final;

Also, there are another solution using for loop:

<?php
$num = 99.999;
$num = "$num"; //casting number to be string
$final = '';
for ($i =0; $i < strlen($num); $i++){
   if ($num[$i] == '.') continue;
   $final .= $num[$i];
}
echo $final;

Try:

$num = 1.11; // number 1.11
$num_to_str = strval($num); // convert number to string "1.11"
$no_decimals = str_replace(".", "", $num_to_str); // remove decimal point "111"
$str_to_num = intval($no_decimals); // convert back to number 111

All in one line would be something like:

$num_without_decimals = intval(str_replace(".", "", strval(1.11)));

You could just treat it as a string and remove the . character:

$num = str_replace ('.', '', $num);

If you want to simply remove the decimal, you can just replace it. 

str_replace('.', '', $string);

This should work for you:

<?php

    $str = "9.99";
    echo $str = str_replace(".", "", $str);

?>

Output:

999
