Convert dot syntax like "this.that.other" to multi-dimensional array in PHP

Question

Just as the title implies, I am trying to create a parser and trying to find the optimal solution to convert something from dot namespace into a multidimensional array such that

s1.t1.column.1 = size:33% 

would be the same as

$source['s1']['t1']['column']['1'] = 'size:33%'; 

Answer 1

Try this number...

function assignArrayByPath(&$arr, $path, $value, $separator='.') {     $keys = explode($separator, $path);      foreach ($keys as $key) {         $arr = &$arr[$key];     }      $arr = $value; } 

CodePad

It will loop through the keys (delimited with . by default) to get to the final property, and then do assignment on the value.

If some of the keys aren't present, they're created.
