Arrays are one thing I am trying to strengthen my skills on and have come upon a task that has stumped me for a bit now.
I have a database field called parameters, which contains data that looks like...
I have built a function to seperate the entire string as an array, getting the keys of this, what, and how. It also grabs the keys, that, where, and when.
I have a class to do all this, and class vars to contain the keys, to contain the original array, and to contain the values. What I am trying to do and what is stumping me is how to grab the value of a specific key.
The constructor process and parses the string into an array by calling the parse($string) method. Then I have another method called getValue($key), which is supposed to get a value of the array by the key.
This is all kinda hard to explain, but let me just show you some sloppy code ;)
/**@var array of parameters */
var $_params = null;
/** @var keys of array */
var $_keys = null;
/** @var values of array */
var $_values = null;
* Parses and grabs keys and values from database parameter set
* @param string Row from table to parse
public function __construct($string)
$this->_params = $this->parse($string);
* Parses string to seperate values and keys from comma seperated spacers
* @param string String to parse
protected function parse($string)
// We need to split the string on , to get what=what, then slit that on = to get value
$split = explode(',', $string);
// Set a few array elements for containers of seperated data
$sep = array();
// Cycle through split string, setting values and keys
$i = 0; // For incrementing
foreach($split AS $splited)
$sep = explode('=',$splited);
$this->_values = $sep[$i];
$this->_keys = $sep[$i];
* Gets param value by key
* @param string key name
public function getValue($key)
$key = trim($key);
// Check if array key exists
// Ive tried numerous things here, but cant seem to get it...
Can anyone more familiar with arrays offer a bit of assistance, or point me to what array function I should be checking out? I have downloaded the manual ( that is such a handy thing to have around ) and have been searching through the array functions but haven't seen anything yet to do this easily.
