<span class="keyword" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); color: rgb(178, 148, 187);"><span class="keyword" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">foreach</span></span>(<span class="variable" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); color: rgb(181, 137, 0);"><span class="variable" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">$numbers</span></span> <span class="keyword" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); color: rgb(178, 148, 187);"><span class="keyword" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">as</span></span> <span class="variable" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); color: rgb(181, 137, 0);"><span class="variable" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">$item</span></span>) {
      <span class="keyword" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); color: rgb(178, 148, 187);"><span class="keyword" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">echo</span></span> <span class="variable" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); color: rgb(181, 137, 0);"><span class="variable" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">$item</span></span>;
  }
<span class="preprocessor" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0); color: rgb(203, 75, 22);"><span class="preprocessor" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">?></span></span>
```
```

we use the `<span class="keyword" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">foreach</span>` keyword to start the loop, followed by parentheses. (This is very similar to what we've done with `<span class="keyword" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">for</span>` loops.)

Between the parentheses, we use the`<span class="variable" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">$numbers</span> <span class="keyword" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">as</span> <span class="variable" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">$item</span>`) syntax to tell PHP: "For each thing in `<span class="variable" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">$numbers</span>`, assign that thing temporarily to the variable`<span class="variable" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">$item</span>`." (We don't have to use the name `<span class="variable" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">$item</span>`—just as with `<span class="keyword" style="-webkit-tap-highlight-color: rgba(0, 0, 0, 0);">for</span>` loops, we can call our temporary variable anything we want.)
