PHP: Split string

Question

How do I split a string by . delimiter in PHP? For example, if I have the string "a.b", how do I get "a"?

Answer 1

explode does the job:

$parts = explode('.', $string);

You can also directly fetch parts of the result into variables:

list($part1, $part2) = explode('.', $string);

Answer 2

explode('.', $string)

If you know your string has a fixed number of components you could use something like

list($a, $b) = explode('.', 'object.attribute');
echo $a;
echo $b;

Prints:

object
attribute

Answer 3

$string_val = 'a.b';

$parts = explode('.', $string_val);

print_r($parts);

Answer 4

The following will return you the "a" letter:

$a = array_shift(explode('.', 'a.b'));

Answer 5

Use:

explode('.', 'a.b');

explode

Answer 6

$array = explode('.',$string);

Returns an array of split elements.

Answer 7
