I have a string in php like this one:
$string = "Count the character frequency of this string";
When I used explode function the output display as:
Array (
[0] => Count
[1] => the
[2] => character
[3] => frequency
[4] => of
[5] => this
[6] => string
)
But the output above doesn't satisfied me because I want to achieve an output which looks like this:
Array (
[0] => C
[1] => o
[2] => u
[3] => n
[4] => t
[5] => t
[6] => h
[7] => e
[8] => c
[9] => h
[10] => a
[11] => r
[12] => a
[13] => c
...
)
I want to split into separate letters and omit the spaces.
Use str_split()
after using str_replace()
to get rid of the space characters:
print_r(str_split(str_replace(' ', '', $string)));
If your string will contain other non alphanumeric characters you can use a regex to replace all non-alphanumeric characters:
print_r(str_split(preg_replace('/[^\da-z]/i', '', $string)));
