The `FormatAbstract` class implements the [`FormatInterface`](../08_Format_API/02_FormatInterface.md) interface with basic functional behavior and adds common helper functions for new formats:
|
||
|
|
|
||
|
|
* [setContentType](#the-setcontenttype-function)
|
||
|
|
* [callContentType](#the-callcontenttype-function)
|
||
|
|
* [sanitizeHtml](#the-sanitizehtml-function)
|
||
|
|
* [array_trim](#the-array_trim-function)
|
||
|

# Functions
|
||
|
|
|
||
|
|
## The `setContentType` function
|
||
|
|
|
||
|
|
The `setContentType` function receives a string defining the content type for the HTML header and must return the object instance.
|
||
|
|
|
||
|
|
```PHP
|
||
|
|
setContentType(string): self
|
||
|
|
```
|
||
|
|
|
||
|
|
## The `callContentType` function
|
||
|
|
|
||
|
|
The `callContentType` function applies the content type to the header data and must return the object instance.
|
||
|
|
|
||
|
|
```PHP
|
||
|
|
callContentType(): self
|
||
|
|
```
|
||
|
|
|
||
|
|
## The `sanitizeHtml` function
|
||
|
|
|
||
|
|
The `sanitizeHtml` function receives an HTML formatted string and returns the string with disabled `<script>`, `<iframe>` and `<link>` tags.
|
||
|
|
|
||
|
|
```PHP
|
||
|
|
sanitizeHtml(string $html): string
|
||
|
|
```
|
||
|
|
|
||
|
|
## The `array_trim` function
|
||
|
|
|
||
|
|
The `array_trim` function receives an array of strings and returns the same array with all elements trimmed (like using the `trim` function on all elements)
|
||
|
|
|
||
|
|
```PHP
|
||
|
|
array_trim(array $elements): array
|
||
|
|
```
