Need help making this backward compatible until php upgrade

[xxclear]

Can some help me make this code backward compatible?

 

 

This code works with php 5.3 and above. I need it to work with 5.2.17.

$columns = 'col1, col2, col3';
$values = '$value1, $value2, $value3';

$result = implode(
', ',
array_map(
function ($c, $v) {
return $c . ' = ' . $v;
},
explode(',', $columns),
explode(',', $values)
)
);

var_dump($result); //this returns: col1 = $value1, col2 = $value2, col3 = $value3

Cheers.

array_combine ($columns, $values);

Thanks for your reply, that alone returns:

var_dump($result); //this returns: col1, $value1, col2, $value2, col3, $value3

Notice "=" isn't inserted between each exploded result. What do i need to do to get that function to work between each result?

FYI i get: PHP Parse error: syntax error, unexpected T_FUNCTION, expecting ')'

In the original code.
