How can I remove all spaces from a string in PHP and in Javascript? I want to remove all spaces from the left hand side, right hand side and from between each character.

For Example:

$myString = "  Hello   my     Dear  ";

I want to get this string as "HellomyDear".

Please demonstrate how I can do this in both PHP and Javascript.

Answer 1

PHP

$newString = str_replace(" ","",$myString);

myString.replace(" ", "")

Remove just spaces

Javascript:

var string = original_string.replace(' ', '');
