A small demonstration of self-study for getting started with PHP

　 　　head>

　name();//No parameter function call

function name($age,$height){

　　print "This is a parameterized function
";

　 echo "Height".$height.",Age:".$age."CM";

　}

　name(20,170);

　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"];
