Program Notes

Features: Exceptional invocation efficiency – a random data invocation test involving 790,000 records took only 500 milliseconds. The invocation can be targeted to specific columns or to the entire table. Simple installation – requires just a single PHP function: `function ecms_rand($classid, $num) {global $empire, $dbtbpre;...}`

Recently, the Empire CMS database contained millions of articles; when I tried to load a page via the backend, I noticed that the page was extremely laggy – almost every page experienced similar performance issues. So, I began investigating the problem. The root cause turned out to be a specific PHP file used for refreshing pages in Empire CMS; as the number of articles grew, loading this PHP file for page refreshes became significantly slower. The solution was to locate that specific page-refreshing file and optimize it. However, after resolving the issue, I had somehow forgotten to record the filename – now I need to find it again...

Code is always just a simple matter – as long as you have a word segmentation API, nothing should be a problem! Here's some PHP code: <?php echo' <meta http-equiv="refresh" content="2"/> '; require('../e/...');

Within the Empire framework, I have a new idea: to add a custom table that stores the keywords for all articles and aggregates the corresponding article IDs – essentially creating a search aggregation feature. The advantage of this approach is that it allows you to retrieve articles containing specific keywords directly within the article itself, effectively replacing Empire's built-in related search aggregation functionality! This is because Empire's native related search aggregation feature is too slow – it relies on SQL fuzzy matching and handles datasets of over 100,000 records; if your server performance is suboptimal...

It is troublesome to find codes every time for website optimization, so I will give some backup here, including some custom functions. In fact, most of them are PHP codes. The first category: high-efficiency random calling code <?php $randnum=32; //random number $randids=''; $randdh=''; for($i=1;$i<=$r…

Scroll down to find "SMTP Service Settings"; since we are sending emails, either option (the first or the second) is acceptable – both options support SMTP service – select the first option and click "Enable"; 3. For security verification, select "Send SMS" – follow the on-screen instructions to send a SMS from your mobile device; once completed, click "I've Sent"; 4. Remember the authorization code below and copy it to your clipboard...

When using a `pre` block within the built-in editor of the Empire, an extra line break is always generated. To handle this extra line break, you need to add the following three lines of code: `$string=str_replace(&quot;&lt;pre&gt;\r\n&quot;,&quot;&lt;pre&gt;&quot;,$string); $string=str_replace(&...`

When you press Enter in the EmpireCMS backend editor, a `<br>` tag will appear; this tag can be seen when you view the "Source Code" (in the top-left corner). The `<br>` tag serves as a mandatory line break and is less preferable than the paragraph tag. Although the visual effect of both tags is similar—both cause the text to start on a new line—the paragraph tag makes the page structure more readable when viewed in the source code. Step 1: Locate the following three files: `\e\admi...`
