Add decimal point 2 characters to the right under PHP
I have a large array containing many items containing numeric data.
Example:
3200 34300 1499 12899
I want to convert them to:
32.00
343.00
14.99
128.99
How can I achieve this elegantly in PHP without using regex?
Thanks in advance.

$new_array=array();
foreach($old_array as $value)
{
$new_array[]=number_format(($value/100),2);
}
See number_format if you want to tinker with the thousand separator or something. See foreach if you want to change array values in place.

Or, if you like anonymous functions and PHP 5.3:
$ nums = array (1, 2, 3, 4);
array_walk ($ nums, function (& $ val, $ key) {
$ val = number_format ($ val / 100, 2);
});
print_r ($ nums);
Output:
Array
(
[0] => 1.00
[1] => 2.00
[2] => 3.00
[3] => 4.00
)
Still and everything, the answer is the same: use number_format()
.

Using number_format .
for($i=0;$i<count($array);$i++)
{
$array[$i] = number_format($array[$i]/100,2);
//if you need them as numbers
$array[$i] = (float) number_format($array[$i]/100,2);
}
