php - convert array to string (split 3 words ) -


We have dynamic posts and we should split 3 words of string for use in the url 

  $ this-> Post_message = "This sample is for testing STRING"; If (stroll ($ this- & gt; post_says)> 5) {$ key = '& lt; & Gt; "; $ ~! # $% ^ & Amp;; * _ + = - '; $ bodypost1 = trim ($ this- & gt; post_session, $ key); $ bodypost2 = explosion (' ', $ Bodypost1,3); $ Bodypost = array_shift (',', $ bodypost2);} and {$ bodypost2 = explosion ('', $ this - & amp; post_message, 3); $ bodypost = array_shift (',', $ Bodypost2);}

and this is the URL parameter 

  $ this-> permalink = $ C-> SITE_URL.'view / '. ($ Type == 'private'? 'Private': 'post'). ':'. $ This- & gt; post_id. '/'. $ Bodypost. 'Html';

Back to my URL:

sitename.com/123/THIS.html
should be sitename.com/123/THIS SAMPLHOL

try it 

  $ message = "This is sample for testing" "$ string = implode ('', Array_slice ('', $ message), 0, 3)); Var_dump ($ string); // result ... string (14) "this is sample"

Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
