1. explode () and implode ()

Implode () is used to connect an array, and explode () is used to split an array. in this tutorial, I wrote a comparison between explode () and implode () in the previous php Tutorial.

2. strtolower () and strtoupper ()

Strtolower () converts the string to lowercase, and strtoupper () converts the string to uppercase.

3. substr () truncates a string

Substr (String, Start, SelectNum)
Echo substr ('abcdef', 1); // bcdef

4. htmlspecialchars () and htmlentities ()

Htmlspecialchars () converts special characters to HTML format. the htmlentities () function converts characters to HTML objects.

And so on ....
