PHP Class: KeyValueTextBlock

– 2009-09-02 15:20

Introduction

KeyValueTextBlock is a PHP Class. I use it on systems where the function http_parse_headers() is not available. It takes a block of text, splits it into records, and splits each record into a key/value pair. After that, you can get a specific value, or all key/value pairs.

Code Sample

class KeyValueTextBlock
{
	private $str;
	private $arr;
	private $out = array();
	private $delimiter_record = "/\s/";
	private $delimiter_hash = ": ";
	private $preserve_replacement;
	private $preserve = " ";
//
	function __construct($str)
	{
		// parse input
		$this->str		 = $str;
		// set a delimiter to provide easily reversible string replacement
		$this->preserve_replacement = md5("mydelimiter");
		// remove regular spaces and preserve them with the delimiter
		$this->str		 = str_replace($this->preserve, $this->preserve_replacement, $this->str);
		// split the input string by all other whitespace
		$this->arr		 = preg_split($this->delimiter_record, $this->str);
		// now we have each line of the string, so let's walk through them all
		foreach($this->arr as $line)
		{
			// put the standard spaces back in
			$line	 = str_replace($this->preserve_replacement, $this->preserve, $line);
			$pieces	 = explode($this->delimiter_hash, $line);
			if(count($pieces) == 2) $this->out[$pieces[0]] = $pieces[1];
		}
	}
//	
	function valueOf($string)
	{
		return $this->out[$string];
	}
	function all()
	{
		return $this->out;
	}
}

Enjoy!
