你有几个选择:
选项 1:使用 $_SERVER['PHP_SELF']、substr() 和 str_replace() 的组合。
选项 2:使用 $_SERVER['PHP_SELF']、rtrim()、explode() 和 count() 的组合。
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");
?>
