创建无数据库PHP图像库

图库.php

<!-- (A) CSS & JS -->
<link href="gallery.css" rel="stylesheet">
<script src="gallery.js"></script>
 
<div class="gallery"><?php
// (B) GET LIST OF IMAGE FILES FROM GALLERY FOLDER
$dir = __DIR__ . DIRECTORY_SEPARATOR . "gallery" . DIRECTORY_SEPARATOR;
$images = glob("$dir*.{jpg,jpeg,gif,png,bmp,webp}", GLOB_BRACE);
 
// (C) OUTPUT IMAGES 
foreach ($images as $i) {
  printf("<img src='gallery/%s'/>", basename($i));
}
?></div>

上面是图像库页面的全部内容

引入CSS

图库.css

/* (A) GALLERY CONTAINER */
/* (A1) ON BIG SCREENS */
.gallery {
  display: grid;
  grid-template-columns: repeat(3, auto); /* 3 IMAGES PER ROW */
  grid-gap: 10px;
  max-width: 1200px;
  margin: 0 auto; /* HORIZONTAL CENTER */
}
/* (A2) ON SMALL SCREENS */
@media screen and (max-width: 640px) {
  .gallery {
    grid-template-columns: repeat(2, auto); /* 2 IMAGES PER ROW */
  }
}
 
/* (B) THUMBNAILS */
.gallery img {
  width: 100%;
  height: 200px;
  /* FILL, CONTAIN, COVER, SCALE-DOWN : USE WHICHEVER YOU LIKE */
  object-fit: cover;
}
.gallery img:fullscreen { object-fit: contain; }
 
/* (X) DOES NOT MATTER */
body, html {
  padding: 0;
  margin: 0;
}

加载Js全屏图像

图库.js

window.addEventListener("DOMContentLoaded", () => {
  // (A) GET ALL IMAGES
  var all = document.querySelectorAll(".gallery img");
 
  // (B) CLICK ON IMAGE TO TOGGLE FULLSCREEN
  if (all.length>0) { for (let img of all) {
    img.onclick = () => {
      // (B1) EXIT FULLSCREEN
      if (document.webkitFullscreenElement || document.fullscreenElement) {
        if (document.exitFullscreen) { document.exitFullscreen(); }
        else if (document.webkitExitFullscreen) { document.webkitExitFullscreen(); }
      }

      // (B2) ENGAGE FULLSCREEN
      else {
        if (img.requestFullscreen) { img.requestFullscreen(); }
        else if (img.webkitRequestFullscreen) { img.webkitRequestFullscreen(); }
      }
    });
  }}
});

这里已经可以引入并生成画廊，如果你还想

文件名作为图像标题

标题库.php

foreach ($images as $i) {
  $img = basename($i);
  $caption = substr($img, 0, strrpos($img, "."));
  printf("<figure><img src='gallery/%s'/><figcaption>%s</figcaption></figure>", $img, $caption);
}

进行图像排序

按日期排序

usort($images, function($file1, $file2) {
  // NEWEST FILE FIRST
  return filemtime($file2) <=> filemtime($file1); 
  // OLDEST FILE FIRST
  // return filemtime($file1) <=> filemtime($file2);
});

按文件名排序

<h1>CATEGORY A</h1>
<div class="gallery"><?php
  $images = glob(FOLDER A);
  foreach ($images as $i) { printf("<img ... />"); }
?></div>
 
<h1>CATEGORY B</h1>
<div class="gallery"><?php
  $images = glob(FOLDER B);
  foreach ($images as $i) { printf("<img ... />"); }
?></div>

现在只需将图像放入不同的类别文件夹中，然后重复"获取文件列表并输出HTML"即可
