To convert a PHP array into string form, you can use the `implode()` function.

The following is the detailed sample code:

```php
<?php
// 声明一个数组
$fruits = array(&#39;apple&#39;, &#39;banana&#39;, &#39;orange&#39;);
// 使用 implode() 函数将数组转化为以逗号分隔的字符串形式
$fruit_string = implode(&#39;,&#39;, $fruits);
// 输出结果
echo $fruit_string; // 输出：apple,banana,orange
?>

In the above code, the `implode()` function converts the `$fruits` array into a comma-separated string `$fruit_string`. By outputting it, you can see that the result is "apple,banana,orange".

In addition to commas, other delimiters can also be used. For example, if you want to use a space to separate the string, just replace the `','' argument with `' '`.
