Sunday, September 21, 2008

Delimits a portion of text to the number of "words":

PLAIN TEXT
PHP:
  1. / **
  2. * String word cut
  3. *
  4. * @ Private
  5. * /
  6. $c , $l ) { wordCut function ($ c, $ l) (
  7. explode ( ' ' , $c ) ; $ c = explode ( '', $ c);
  8. $i = 0 ; $i < $l ; $i ++ ) $r [ $i ] = $c [ $i ] ; for ($ i = 0; $ i <$ l, $ i + +) $ r [$ i] = $ c [$ i];
  9. implode ( ' ' , $r ) . '...' ; $ r = implode ( '', $ r).'...';

    My tagliaStringa ($ string, $ numParole) is a bit 'different ... Not use two arrays, but builds the string by inserting the words as a variable, then cutting off the last space and adding three dots ...

    What?

    @ Tom: Oh, an example for a function "cut the strings" is a bit 'too ... :) However, for example, you can use to:

    PLAIN TEXT
    PHP:
    1. wordCut ( 'Stringa di esempio abbastanza lunga per essere tagliata' , 5 ) ; $ res = wordCut ( 'sample string long enough to be cut', 5);

    'll Get in $res 

      Sample string long enough ...

    @ Napolux: I searched in vain for your role on your blog ... cmq even so would be fine:

    PLAIN TEXT
    PHP:
    1. $c , $l ) { wordCut function ($ c, $ l) (
    2. explode ( ' ' , $c ) ; $ c = explode ( '', $ c);
    3. $i = 0 ; $i < $l ; $i ++ ) $r [ $i ] = ( $i == 0 ) ? $c [ $i ] : ( ' ' . $c [ $i ] ) ; for ($ i = 0; $ i <$ l, $ i + +) $ r [$ i] = ($ i == 0)? $ c [$ i]: ( ''. $ c [$ i] )
    4. $r . '...' ) ; return ($ r.'...');
    5. )

    Note the "treat" for not trying to eliminate the extra space :)

    @ Julius: Please dear! Although no one has noticed that for large strings to its proper function would be:

    PLAIN TEXT
    PHP:
    1. $c , $l ) { wordCut function ($ c, $ l) (
    2. explode ( ' ' , $c ) ; $ a = explode ( '', $ c);
    3. count ( $a ) > $l ) { if (count ($ a)> $ l) (
    4. $i = 0 ; $i < $l ; $i ++ ) $r [ $i ] = $a [ $i ] ; for ($ i = 0; $ i <$ l, $ i + +) $ r [$ i] = $ a [$ i];
    5. implode ( ' ' , $r ) . '...' ; $ r = implode ( '', $ r).'...';
    6. ; return $ r;
    7. $c ; ) Else return $ c;
    8. )
