Three ways to pass in parameters in php

1. Use $argv or $argc parameters to receive

<?php
/**
 * 使用 $argc $argv 接受参数
 */
echo "接收到{$argc}个参数";
print_r($argv);

The following are the results of the test

2. Use getopt function (this method is recommended)

$param_arr = getopt(&#39;a:b:&#39;);
print_r($param_arr);

. Input data through the user

<?php
/**
 * 提示用户输入，类似Python
 */
fwrite(STDOUT,'please input:');
echo 'your input is:'.fgets(STDIN);

The user’s input cannot be empty

<?php
/**
 * 提示用户输入，类似Python
 */

$fs = true;

do{
    if($fs){
        fwrite(STDOUT,'请输入您的博客名：');
        $fs = false;
    }else{
        fwrite(STDOUT,'抱歉，博客名不能为空，请重新输入您的博客名：');
    }

$name = trim(fgets(STDIN));

}while(!$name);

echo '您输入的信息是：'.$name."\r\n";
