Having some trouble with this operation, found that you can use string replacement syntax to also split a string to array:
NPM_VER=$(npm -v) # 6.12.1
NPM_VER=(${NPM_VER//./ }) # Split on '.' as delimiter
echo "${NPM_VER[0]}" # 6
echo "${NPM_VER[1]}" # 12
echo "${NPM_VER[2]}" # 1
PHP functions for creating and decipering URL-safe strings are urlencode and urldecode.
Javascript functions for creating and deciphering URL-safe strings are escape and unescape.
PHP’s urlencode replaces spaces with + and Javascript’s escape replaces spaces with %20. So if you are decocing a string from PHP with Javascript, you have to replace all the + in the string with spaces using the JS string.replace function. Since + is an operator in Javascript, it has to be escaped with a backslash ( \ ) for the function to execute without error. The g flag has to be included to replace all instances of occurance ( g = global):
string.replace ( /\+/g, ' ' );
