这篇文章主要介绍了关于使用php如何扫描url死链接，有着一定的参考价值，现在分享给大家，有需要的朋友可以参考一下
* 从Packagist上搜索需要的包
https://packagist.org/
* 通过composer下载依赖包
composer require guzzlehttp/guzzle composer require league/csv
* 使用composer自动加载器, 编写scan.php
<?php
// 1. 使用composer自动加载器
require 'vendor/autoload.php';
use GuzzleHttp\RequestOptions;
// 2. 实例Guzzle HTTP客户端
$client = new \GuzzleHttp\Client();
$options = [
RequestOptions::TIMEOUT => 3,
RequestOptions::DECODE_CONTENT => false,
RequestOptions::HEADERS => [
'User-Agent' => 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/67.0.3396.99 Safari/537.36',
]
];
// 3. 打开迭代处理csv
// 或者传用户自定义命令行参数指定输入文件 $argv[1]
// $file = new SplFileObject('../data/t_video.csv'); /* $csvRow[4], $csvRow[5] */
$file = new SplFileObject('../data/urls.csv');
$csv = \League\Csv\Reader::createFromFileObject($file);
foreach ($csv as $csvRow) {
$url = $csvRow[0];
echo 'scanning ',$url,'... ';
try {
// 4. 发送http options请求
$httpResponse = $client->request('GET', $url, $options);
// 5. 检查http相应的状态码
$code = $httpResponse->getStatusCode();
if ($code === 200) {
echo "\033[32m[OK]\033[0m",PHP_EOL;
} else {
throw new \Exception();
}
} catch (\Exception $e) {
// 6. 把死链发给标准输出
// echo $url.PHP_EOL;
echo "\033[31m[ERROR]\033[0m ".$e->getMessage().PHP_EOL;
}
}* input csv:
../data/urls.csv

output:
* 在Linux终端输出带颜色的文字的方法
注意 echo "" 要用双引号, 单引号会原样输出 \033[32mxxx\033[0m
一、shell下的实现方法
只要设置输出属性，就可输出带颜色的文字 ，shell中的部分属性：
\033[0m 关闭所有属性
\033[1m 设置高亮度
\033[4m 下划线
\033[5m 闪烁
\033[7m 反显
\033[8m 消隐
\033[30m 至 \33[37m 设置前景色
\033[40m 至 \33[47m 设置背景色
\033[nA 光标上移n行
\033[nB 光标下移n行
\033[nC 光标右移n行
\033[nD 光标左移n行
\033[y;xH设置光标位置
\033[2J 清屏
\033[K 清除从光标到行尾的内容
\033[s 保存光标位置
\033[u 恢复光标位置
\033[?25l 隐藏光标
\033[?25h 显示光标
各数字所代表的颜色如下：
字背景颜色范围:40----49
40:黑
41:深红
42:绿
43:黄色
44:蓝色
45:紫色
46:深绿
47:白色
字颜色:30----39
30:黑
31:红
32:绿
33:黄
34:蓝色
35:紫色
36:深绿
37:白色
使用，如：echo -e "\033[34mHello, world!" (-e作用是引导设置输出属性)，
恢复属性为默认值：echo -e "\033[0m"，
同类的多种设置项可以组合在一起，中间用分号（;）隔开。如下：
echo -e "\033[20;1H\033[1;4;34mHello,world\033[0m"

Explain secure password hashing in PHP (e.g., password_hash, password_verify). Why not use MD5 or SHA1?
Apr 17, 2025 am 12:06 AM
In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
