regex line break code example

Example 1: regex start line

// Match from the start of the line
^
//example:
let str = "HELLO hello world"
let reg = /hello/g //g option: doesn't stop at first match
str.match(reg) // Array(2)["HELLO", "hello"]
reg = /^hello/g //match hello at the start of the string
str.match(reg) // Array(1)["HELLO"]

Example 2: multi line dot match php

// This problem can be solved adding the “s” modifier to the regular
// expression. With this modifier, the “.” wildcard character matches 
//any possible character in the string, including newlines:

preg_match("#<body>(.*)</body>#s",$document,$matches)
