How can the use of a development environment help prevent errors when making changes to PHP code?

Using a development environment can help prevent errors when making changes to PHP code by providing features such as syntax highlighting, code completion, and debugging tools. These tools can help catch syntax errors, typos, and other common mistakes before the code is executed, saving time and preventing potential bugs in the final product.

```php
// Example of using a development environment to prevent errors
// This code snippet demonstrates how syntax highlighting and code completion can help identify errors before execution

$variable = "Hello, World";

// Trying to echo a variable that doesn't exist
echo $varible;
```
In this example, a typo in the variable name `$varible` is easily spotted with syntax highlighting, preventing a runtime error.
