class pdf_context {

PSR1 recommends that each class must be in a namespace of at least one level to avoid collisions.

	var $file;

The visibility should be declared for property $file.

	var $buffer;

The visibility should be declared for property $buffer.

	var $offset;

The visibility should be declared for property $offset.

	var $length;

The visibility should be declared for property $length.

	var $stack;

The visibility should be declared for property $stack.

	// Constructor


	function pdf_context($f) {

It is generally recommended to explicitly declare the visibility for methods.

Please use __construct() instead of a PHP4-style constructor that is named after the class.

		$this->file = $f;

		$this->reset();

	}


	// Optionally move the file

	// pointer to a new location

	// and reset the buffered data


	function reset($pos = null, $l = 100) {

It is generally recommended to explicitly declare the visibility for methods.

		if (!is_null ($pos)) {

			fseek ($this->file, $pos);

		}


		$this->buffer = $l > 0 ? fread($this->file, $l) : '';

		$this->length = strlen($this->buffer);

		if ($this->length < $l)

            $this->increase_length($l - $this->length);

		$this->offset = 0;

		$this->stack = array();

	}


	// Make sure that there is at least one

	// character beyond the current offset in

	// the buffer to prevent the tokenizer

	// from attempting to access data that does

	// not exist


	function ensure_content() {

It is generally recommended to explicitly declare the visibility for methods.

		if ($this->offset >= $this->length - 1) {

			return $this->increase_length();

		} else {

			return true;

		}

	}


	// Forcefully read more data into the buffer


	function increase_length($l=100) {

It is generally recommended to explicitly declare the visibility for methods.

		if (feof($this->file)) {

			return false;

		} else {

			$totalLength = $this->length + $l;

		    do {

                $this->buffer .= fread($this->file, $totalLength-$this->length);

            } while ((($this->length = strlen($this->buffer)) != $totalLength) && !feof($this->file));
