Useful Plugins

`NanoMVC_Library_URI`

This plugin provides tools for working with URL segments in NanoMVC.

segment(int $index = 1): string|false — Returns the N-th URI segment (starting from 1). Returns false if it doesn’t exist.
uri_to_assoc(int $index = 1): array — Converts URI segments into an associative array starting from the given index. Useful for parsing /key1/value1/key2/value2-style URLs.
uri_to_array(int $index = 1): array|false — Returns all URI segments as an indexed array starting at the given position.
uri(int $index = 1): ?string — Returns the remaining URI path from the given segment index as a string.
parse_query_string(string $query = ''): array — Parses a query string into an array of ['key' => ..., 'val' => ...] pairs. Empty keys or values are allowed and preserved.

A utility plugin for debugging, redirection, sending headers, view rendering, and type checking.

debug(mixed $var, ?string $name = null, bool $return = false, bool $esc = true, bool $hide = false): ?string
Displays a formatted debug window of the given variable. Can optionally return the result instead of printing it, escape HTML, or hide the output in HTML comments.
redirect(string $uri, ?int $code = null): false
Sends a redirect to the given URI, optionally with a status code (e.g. 301).
send_headers(array $headers = [], bool $replace = true): bool
Sends raw or associative headers safely. If a header line includes an HTTP status, it will be recognized and handled.
esc_html(string $text): string
Escapes HTML special characters for safe output (using ENT_QUOTES | ENT_SUBSTITUTE).
view(string $filename, ?array $vars = null): void
Renders a view file with optional variables. This method is useful to call a view from within another view.
Example usage:
```
NanoMVC_Script_Helper::view('pagination_view', $vars); // Similar parameters as the controller's view->display() method.
```
is_int_like(mixed $value): bool
Checks if a value is an integer or an integer-like string (e.g., "42" or -7).
