This `<span class="operator" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);"><span class="keyword" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">do</span></span>` / `<span class="keyword" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">while</span>` loop only runs once and then exits:

1. First we set `<span class="variable" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">$i</span>` equal to `0`.
2. Second, the loop runs once and outputs `<span class="variable" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">$i</span>`, which is `0`.
3. Then the condition `<span class="keyword" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">while</span> (<span class="variable" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">$i</span> ><span class="number" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">0</span>);` is checked. Since `<span class="variable" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">$i</span>` is not greater than 0, the condition evaluates to`<span class="identifier" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);"><span class="keyword" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">false</span></span>, <span class="identifier" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);"><span class="keyword" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">and</span></span> <span class="identifier" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">the</span>`do`/`while` loop stops.
