 The following These are some knowledge points recorded by newcomers’ self-study. If the masters don’t like it, please don’t comment.

 There are two main types of output statements in PHP;

 1: print, output a single variable or string;

 2: echo, output multiple variables or strings, and the execution efficiency is better than print Much faster.

 3: PHP is a weakly typed language;

 4: Loops, judgments, and branch selection statements in PHP are similar to those in C# and js;

 5: The array naming method is a bit unique:;172,"weight"=>60);

   The index does not necessarily start from [0], but the "age", "height" and "weight" defined by ourselves;

    If you want to get the elements in the array, you can only use $man["age"], $man["height"], $man["height"];
