目录中的 Zip 文件使用 URL 的一部分作为文件名

Question

我使用 php 文件创建文件夹中所有 jpg 文件的 zip 存档，并使其可供下载。这是脚本：<?php$zip = new ZipArchive;$download = 'FileName.zip';$zip->open($download, ZipArchive::CREATE);foreach (glob("*.jpg") as $file) { /* Add appropriate path to read content of zip */    $zip->addFile($file);}$zip->close();header('Content-Type: application/zip');header("Content-Disposition: attachment; filename = $download");header('Content-Length: ' . filesize($download));header("Location: $download");?>我想知道是否可以使用 url 的一部分作为存档名称？我的网址如下所示：https://www.example.com/data/pictures/album/我希望存档名称为Pictures-Album-CustomText.zip

Answer 1

您有几个选择：

$_SERVER['PHP_SELF']选项 1：使用、substr()和的组合str_replace()。

$_SERVER['PHP_SELF']选项 2：使用、rtrim()、explode()和的组合count()。

第一个选项，细分：

$url = $_SERVER['PHP_SELF'];              // the current full url

strrpos($url, "pictures/")                // finds "pictures/" in the $url variable

substr($url, strrpos($url, "pictures/"))  // extracts everything from "pictures/" onwards

str_replace("/","-", $name_pre);          // replaces "/" with "-" 

<?php

    $url = $_SERVER['PHP_SELF'];

    $name_pre = substr($url, strrpos($url, "pictures/"));

    $name_pre = str_replace("/","-", $name_pre);

    $zip = new ZipArchive;

    $download = $name_pre . 'FileName.zip';

    $zip->open($download, ZipArchive::CREATE);

    foreach (glob("*.jpg") as $file) { 

       $zip->addFile($file);

    }

    $zip->close();

    header('Content-Type: application/zip');

    header("Content-Disposition: attachment; filename = $download");

    header('Content-Length: ' . filesize($download));

    header("Location: $download");

?>

第二个选项，细分：

$url = rtrim($_SERVER['PHP_SELF'], "/"); // get url and remove trailing "/"

$url_pieces = explode('/', $url);        // break string into pieces based on "/"

$url_pieces_count = count($url_pieces);  // count the number of pieces

$name_pre = $url_pieces[($url_pieces_count - 2)] . "-" . $url_pieces[($url_pieces_count - 1)] . "-"; // construct the filename preface

<?php

    $url = rtrim("https://www.example.com/data/pictures/album/", "/");

    $url_pieces = explode('/', $url);

    $url_pieces_count = count($url_pieces);

    $name_pre = $url_pieces[($url_pieces_count - 2)] . "-" . $url_pieces[($url_pieces_count - 1)] . "-";

    $zip = new ZipArchive;

    $download = $name_pre . 'FileName.zip';

    $zip->open($download, ZipArchive::CREATE);

    foreach (glob("*.jpg") as $file) { 

       $zip->addFile($file);

    }

    $zip->close();

    header('Content-Type: application/zip');

    header("Content-Disposition: attachment; filename = $download");

    header('Content-Length: ' . filesize($download));

    header("Location: $download");

?>

Answer 2

这成为我的最终代码（@Mech 代码 + ucwods），我使用 ucwords 来对单词进行功能化 -

<?php

$url = rtrim($_SERVER['PHP_SELF'], "/"); // get url and remove trailing "/"

$url_pieces = explode('/', $url);

$url_pieces_count = count($url_pieces);

$name_pre = $url_pieces[($url_pieces_count - 3)] . "-" . $url_pieces[($url_pieces_count - 2)] . "-";

$name_final = ucwords($name_pre, "-");

$zip = new ZipArchive;

$download = $name_final . 'FileName.zip';

$zip->open($download, ZipArchive::CREATE);

foreach (glob("*.jpg") as $file) { 

   $zip->addFile($file);

}

$zip->close();

header('Content-Type: application/zip');

header("Content-Disposition: attachment; filename = $download");

header('Content-Length: ' . filesize($download));

header("Location: $download");

?>
