it fixes the issue Fairly new to PHP and trying to figure out something that I can't get my head around too.
code :
$str = 'http://url.com/search/?location=london&page_number=1';
$str = preg_replace('/[?&]page_number=\d+/', '', $str);

I think the issue was by ths following , I have a few functions that aim to convert a user input as a string to a binary number. This is part of a basic 'assembler' program I am working on. Here is my code: , You're not passing the input if there's no #
code :
function generateBinaryNumber(inputValue) //only works for hash!
{
    var number; //number is not set

    if(containsHash(inputValue) != -1) 
    {
        //number is set here, but only if the if statement is true
        number = getNumberFromString(inputValue);
    }
    //if containsHash was false, number is undefined
    return decimalToBinary(number);
}

seems to work fine Please see the RegExp reference on MDN. This explains how RegExp patterns in JavaScript work.
For 'beginning of string', use ^. For 'zero or more times', use *. For 'one or more times', use +.
code :
var re = /^(Copy of )*/;
console.log('Copy of Copy of Copy of This is my String'.replace(re, ''));
console.log('Copy of This is my String'.replace(re, ''));
console.log('This is my String'.replace(re, ''))

it should still fix some issue I have a String in Java: , Simple fragment that will also handle the other dashes.
code :
public class Test {

    public static void main(String[] args) {
        printFormattedText("-Hello-World. My 123-phone number-456 is 333-333-333");
        printFormattedText("-123 Hello-World. My 123-phone number-456 is 333-aaa-333-");
    }

    private static void printFormattedText(String input) {
        String result = input.replaceAll("^\\-|(\\D)\\-|\\-(\\D)|\\-$", "$1 $2");
        System.out.println(result);
    }

}
 Hello World. My 123 phone number 456 is 333-333-333
 123 Hello World. My 123 phone number 456 is 333 aaa 333
