explode（）一个字符串。 脱掉空白[关闭]

Question

I need to explode $k like this

$kExploded = explode(" ", $k);

Now if it ca be useful I also add that

var_dump($k)= string(20) "2013-01-01 12:00:00 " string(20) "2013-01-02 12:00:00 " 
               string(20) "2013-01-03 12:00:00 " 

How to explode $K?

if I echo out $k returns this

2013-01-01 12:00:00 2013-01-02 12:00:00 2013-01-03 12:00:00

I just would like to get this:

2013-01-0112:00:002013-01-0212:00:002013-01-0312:00:00//take off all white space

Answer 1

It has been answered many times on Stackoverflow, perhaps you should have researched first, but this should solve the problem:

preg_replace('/\s+/', '', $k);
