合并两个数组，使它们具有相同的索引号

Question

Maybe an easy question, but I am having trouble with two arrays. I want each element in the 'test' array to represent an index in the 'foo' array. I hope this makes sense.

<?php
$test = array(1=>50,60,70);

$foo = array('age', 'money', 'number');
?>

Answer 1

Try this:

$new_array  =   array_combine($test, $foo);
echo "<pre>";
print_r($new_array);
echo "</pre>";

This gives:

Array
(
 [50] => age
 [60] => money
 [70] => number
)
