Question

How can I dynamically create variable names based on an array? What I mean is I want to loop through this array with a foreach and create a new variable $elem1, $other, etc. Is this possible?

$myarray = array('elem1', 'other', 'elemother', 'lastelement');
foreach ($myarray as $arr){
    //create a new variable called $elem1 (or $other or $elemother, etc.) 
    //and assign it some default value 1
}

Answer 1

foreach ($myarray as $name) {
   $$name = 1;
}

This will create the variables, but they’re only visible within the foreach loop. Thanks to Jan Hančič for pointing that out.
