I have an array with unknown information. I want to get each element and assign it to a variable so I can use it elsewhere.
This works but it only gets the first element.
function firstElement($foo,$m='k') {
foreach ($foo as $k=>$v){
return $$m;
}
}
$firstKey=firstElement($foo);
$firstVal=firstElement($foo,'v');
You could use the extract() PHP function. If you want to doit yourself:
Remove the "return" statement from there. Once you "return" a value, the foreach and the entire functions stops.
The extract() function will pull out each array key and assign the value to a variable. If the key is, for example, 'color', then it will name the new variable $color and assign the value from the array key to it.
extract($foo);
Answering my own question:
To find out what the name was assigned to each element I used print_r($foo);
This gave me:
array("a" => "blah", "b" => "blah")
Then I used extract
extract($foo);
//echo "$a";
//echo "$b";
extract()built-in function insteadextract(), though if they are in an array, perhaps they are related and belong in an array?
