I have a text document that I would like to substrate. I have the following codes are using substring of: 

  substr (text, start + end-start)   
 Initially, a vector of 60 elements. However, the above code only returns the value of  substr (text, 110 9, 110 + 199) . I have all 60 elements, namely  
     
  •   substr (text, 1109,1109 + 199)   
  •   substr how to return (Text, 115 9, 115 + 9 199)   
  •  ....   
     Sample data  
      Start [1] 11009 11590 11972 15674 16274 16659 19866 20541 20 9 63 24787 25376 [12] 25746 29458 30011 30363 34086 34702 35087 38643 39095 39416 42626 [23] 43188 43545 46731 47367 47757 51029 51673 52072 55444 56076 56470 [34] 59794 60445 60851 64267 64877 65276 68659 69200 69547 72747 73303 [45] 73657 76896 77648 78103 81541 82050 82391 85277 85848 86227 89128 [56] 89,656 90010 92,830 93,329 93,656 end 1 199 199 199 201 201 201 218 218 218 186 186 186 177 177 177 192 192 [18] 192 160 160 160 178 178 178 194 194 194 200 200 200 197 197 197 205 [35] 205 205 200 200 200 174 17 4 174 178 178 178 235 235 235 171 171 171 [52] 190 190 190 179 179 179 169 169 169    
     text after 
     
      substr  in place you can use a substring:  
      sub-base (your_text, first = start, last = (start + end ))

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no.
