我使用 php 文件創(chuàng)建文件夾中所有 jpg 文件的 zip 存檔，并使其可供下載。這是腳本：<?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 的一部分作為存檔名稱？我的網(wǎng)址如下所示：https://www.example.com/data/pictures/album/我希望存檔名稱為Pictures-Album-CustomText.zip

您有幾個(gè)選擇：
$_SERVER['PHP_SELF']選項(xiàng) 1：使用、substr()和的組合str_replace()。
$_SERVER['PHP_SELF']選項(xiàng) 2：使用、rtrim()、explode()和的組合count()。
第一個(gè)選項(xiàng)，細(xì)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");
?>
第二個(gè)選項(xiàng)，細(xì)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");
?>

這成為我的最終代碼（@Mech 代碼 + ucwods），我使用 ucwords 來對單詞進(jìn)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");
?>
