开始教程

第一步：

新在本文最底部查看原文下载我制作好的 60s.php 文件。
或者新建一个 60s.php 文件，将 60s.php 文件上传到您需要放置的目录上。
复制粘贴以下代码到 60s.php 文件中保存。

<?php
$date = file_get_contents("https://www.zhihu.com/api/v4/columns/c_1261258401923026944/items");
$date = json_decode($date);
$content = $date->data[0]->content;
$pattern ='';
preg_match($pattern,$content,$matches);
$src_path = $matches[1];
$src = imagecreatefromstring(file_get_contents($src_path));
$info = getimagesize($src_path);
//裁剪开区域左上角的点的坐标
$x = 0;
$y = 0;
//裁剪区域的宽和高
$width = 720;
$height = 350;
//最终保存成图片的宽和高，和源要等比例，否则会变形
$final_width = 720;
$final_height = round($final_width * $height / $width);
//将裁剪区域复制到新图片上，并根据源和目标的宽高进行缩放或者拉升
$new_image = imagecreatetruecolor($final_width, $final_height);
imagecopyresampled($new_image, $src, 0, 0, $x, $y, $final_width, $final_height, $width, $height);
$ext = pathinfo($src_path, PATHINFO_EXTENSION);
$rand_name = date("Ymd") . "." . $ext;
//创建文件夹保存图片
if (!file_exists("60s")){
    mkdir ("60s",0777,true);
}
imagejpeg($new_image,"60s/".$rand_name);
imagedestroy($src);
imagedestroy($new_image);
$content = strip_tags($content,'');
$content = ''.$content;
require __DIR__ . '/wp-config.php';
