Function extract_string_literal

src/parser/classes.rs:499–518

Extract the string content from a PHP string literal. Strips surrounding quotes (single or double) and returns the inner text. Returns `None` if the text is not a quoted string. Also handles: - `SomeCast::class` — returns `"SomeCast"` - `Address::class.':argument'` — strips the concatenated argument suffix and returns `"Address"`

(text: &str)

/// - `Address::class.':argument'` — strips the concatenated argument
///   suffix and returns `"Address"`

    let t = text.trim();

        && t.len() >= 2
    {
        return Some(t[1..t.len() - 1].to_string());
    }
    // For class-string cast values like `SomeCast::class` or
    // `SomeCast::class.':argument'`, extract the class name.
    // The concatenation dot may have surrounding whitespace, so
    // look for `::class` and take everything before it.
