Trim comma and whitespacing from number

I am using this function to convert square meters to square foot.

$sinput = rtrim(get_field('fl_area'), ", \t\n");  
if(trim($sinput) == "0"){echo ' ' ;} else {$soutput = metersToSquareFeet($sinput); echo $soutput . ' sq. m (' . number_format($sinput ) . ' sq. f)' ;} 

function metersToSquareFeet($meters, $echo = true)
{
    $m = $meters;
    $valInFeet = $m*10.7639;
    $valFeet = (int)$valInFeet;
    if($echo == true)
    {
        echo $valFeet;
    } else {
        return $valFeet;
    }
}

Problem I have is with line:

rtrim(get_field('fl_area'), ", \t\n");

The user enters the number in the format 3,246 and i want to convert this to 3246 for my function to work.

Of course I could also modify the function somehow and not use rtrim in the first place

You can use str_replace() to remove all occurrences of commas and spaces from the string:

$m = str_replace(array(',',' '), '', $m);

Or even strtr():

$m = strtr($m, array(',' => '', ' ' => ''));

This is likely to be faster than regular expessions. However, if the number of function calls are minimal, the difference wouldn’t be noticeable.

You have a few options but probably your easiest one is to remove all non-numeric characters.

Not sure what your get_field does but assuming it just gets the field from the Input you could use regex like so.

$sinput = preg_replace( '/[^0-9]/', '', $get_field('fl_area') );

Try this:

str_replace(array(',',' '), '', get_field('fl_area'));

rtrim only removes characters from the end of the string, not the middle. Use preg_replace:

$sinput = preg_replace('/[,\s]+/g', '', get_field('fl_area'));
