I'm trying to pass key values pairs within PHP:
// "initialize"
private $variables;
// append
$this->variables[] = array ( $key = $value)
// parse
foreach ( $variables as $key => $value ) {
//..
}
But it seems that new arrays are added instead of appending the key/value, nor does the iteration work as expect. Please let me know what the proper way is.
Solution
$this->variables[$key] = $value;
did the trick - the iteration worked as described above.
I think you may be looking for:
$this->variables[$key] = $value;
The way you have it right now you are creating an array of arrays, so you would have to do this:
foreach($this->variables as $tuple) {
list($key, $value) = $tuple;
}
Referring to Perl, but helps understand the difference between hashes and arrays:
Some people think that hashes are like arrays (the old name 'associative array' also indicates this, and in some other languages, such as PHP, there is no difference between arrays and hashes.), but there are two major differences between arrays and hashes. Arrays are ordered, and you access an element of an array using its numerical index. Hashes are un-ordered and you access a value using a key which is a string.
