Transformations在phpMyAdmin中用於格式化或修改特定列數(shù)據(jù)的顯示方式，而不改變數(shù)據(jù)庫(kù)中的實(shí)際存儲(chǔ)值。它們通過(guò)提升表格數(shù)據(jù)的可讀性來(lái)增強(qiáng)用戶體驗(yàn)，適用於多種數(shù)據(jù)類型：1. URL字段可自動(dòng)轉(zhuǎn)換為可點(diǎn)擊鏈接；2. 圖像路徑或BLOB可直接顯示為圖片；3. 格式化文本（如BBCode、Markdown）可動(dòng)態(tài)渲染樣式；4. 日期/時(shí)間可自定義顯示格式；5. 長(zhǎng)文本可截?cái)嘁詢?yōu)化展示。應(yīng)用Transformation的步驟包括：打開(kāi)目標(biāo)表的“Structure”標(biāo)籤頁(yè)，點(diǎn)擊字段旁的齒輪圖標(biāo)，在下拉菜單中選擇所需的轉(zhuǎn)換方法並設(shè)置參數(shù)後保存。變換僅影響phpMyAdmin中的數(shù)據(jù)顯示，並不更改數(shù)據(jù)庫(kù)內(nèi)容。常見(jiàn)使用場(chǎng)景包括：顯示HTML片段時(shí)保留換行與縮進(jìn)、將圖像路徑轉(zhuǎn)為縮略圖、渲染base64編碼圖片、以及縮短長(zhǎng)文本字段。這些功能特別適合快速查看數(shù)據(jù)、調(diào)試或供非技術(shù)人員使用，但不應(yīng)取代前端的正式格式化處理。

In phpMyAdmin, "Transformations" are a feature that lets you format or modify how data from specific columns is displayed in the browser without changing the actual stored values in the database. This can be really handy when you're dealing with binary data, URLs, dates, or other special formats that might not look useful in their raw form.

Let's go over how transformations work and how they can help improve readability of your table data.

What Types of Data Can Be Transformed?

phpMyAdmin supports several built-in transformation types, mostly grouped by the kind of data they handle. These transformations apply to specific column types — for example:

• URL fields : Automatically turn text into clickable links.
• Image paths or BLOBs : Display images directly in the table view instead of showing raw binary or path strings.
• Formatted text (BBCode, Markdown) : Render styled content on the fly.
• Date/time formatting : Adjust how timestamps or date fields are shown.
• Truncation or abbreviation : Shorten long text fields for better display.

You don't need to write any custom code for most of these — just select the right transformation from a dropdown when viewing table structure.

How to Apply a Transformation in phpMyAdmin

Applying a transformation is straightforward once you know where to find it. Here's how:

1. Open the table you want to modify.
2. Click the "Structure" tab at the top.
3. Look for the "Transformation" column and click the gear icon next to a field.
4. From the dropdown, choose the desired transformation method.
5. Optionally, enter transformation parameters — for example, specifying image dimensions or truncation length.
6. Save your changes.

Once set up, whenever you browse the table, the selected column will display its transformed version.

?? Keep in mind: Transformations only affect how data appears in phpMyAdmin — they don't alter what gets stored in the database.

When Should You Use Transformations?

Most people use transformations for usability reasons rather than functional ones. For instance:

• If you have a TEXT column storing HTML snippets, applying a transformation like "Text_Plain\formatted" can preserve line breaks and indentation in the display.
• A column containing file paths pointing to images can be turned into inline thumbnails using the "Image_JPEG\inline" transformation.
• Columns with base64-encoded images stored as BLOBs can be rendered directly using the appropriate image transformation type.

This helps developers and administrators quickly interpret data without needing to export or decode manually.

Another common use case is shortening overly long values. If you have a notes field that often contains paragraphs, using "Text_Plain\substr" lets you limit how much is shown per row — say, 30 characters — which keeps the interface clean and fast.

Final Thoughts

Transformations in phpMyAdmin are one of those features that aren't flashy but definitely make life easier when working directly with database tables. They're especially useful for quick visual checks or when handing off access to non-developers who might get confused by raw or encoded data.

They're not meant to replace proper front-end formatting, but they do help during debugging, data review, or basic maintenance tasks.

基本上就這些。
