twigHow to prevent Template Injection in PHP Twig?

Template Injection in PHP Twig can be prevented by using the autoescape tag. This tag will automatically escape any variables that are passed to the template. For example:

{% autoescape true %}
    {{ user_input }}
{% endautoescape %}

This will output the user input as escaped HTML, preventing any malicious code from being executed.

Additionally, the raw tag can be used to prevent any escaping of variables. For example:

{% raw %}
    {{ user_input }}
{% endraw %}

This will output the user input as is, without any escaping.

• autoescape tag: Automatically escapes any variables passed to the template.
• raw tag: Prevents any escaping of variables.
