random

[shage]

Anyone point me in the right direction for a way to have something like

 

I (walked,ran,skipped,jogged) to the market

 

The script would select one word in the () and use it.

 

Thank you

[trq]

<?php

  $words = array('walked','ran','skipped','jogged');
  echo "I ". $words[rand(0,3)] . " to the market";

?>

lol nice thorpe this is kinda hmmmm simple 

[shage]

thats nice but would be a pain to use if i was to write a story and change one word per paragraph, thank you thou

[trq]

You asked for an example, there it is. It would be pretty easy to build upon.

k u the man

[BillyBoB]

why do you think that???

you could do like:

 

<?php

  $verb = array('walked','ran','skipped','jogged');
  $adj = array('orange','red','blue','yellow');
  $noun = array('computer','sign','door','wall');
  echo "I ". $verb[rand(0,3)] . " to the market and saw a " . $adj[rand(0,3)] . " toy car so i stole it and threw it at the " . $noun[rand(0,3)];

?>

 

always an interesting outcome

[trq]

And... to take that a step further.

 

<?php

  function parse_replace($str) {
    $verb = array('walked','ran','skipped','jogged');
    $adj = array('orange','red','blue','yellow');
    $noun = array('computer','sign','door','wall');
    $str = str_replace(
      array('[verb]','[adj]','[noun]'),
      array($verb[rand(0,count($verb)-1)],$adj[rand(0,count($adj)-1)],$noun[rand(0,count($noun)-1)]),
      $str
    );
    return $str;
  }

  echo parse_replace("I [verb] to the market and saw a [adj] toy car so i stole it and threw it at the [noun]");

?>

 

Depends what your doing really.

guys are getting there and looking good, but i cant figure out how to set it up to use the concept of (red,blue,green,orange) in the text and it random one of them, is how its done but cant seem to figure it out.

[trq]

Maybe if you explain exactly what your trying to do / post some code.

You would need to use regular expressions (www.php.net/ereg) to grab all the text data in between parans, than from there filter each of those into an array and do the above code on them to get the one word, put each word in an array and use either str_replace to replace the entire (word,word) with the new word.

 

This takes into account that the text will never have parans as part of the actual text.

 

Shouldn't be too hard to do.

thorpe you are genius man thats pretty great work

[shage]

if i had the code i wouldnt need help, lol

 

The idea that (i,we) have is to have it pick a random word from within the (). This is to allow a story to change depending on every (load, refresh). The thing is (i,we) can't seem to figure out how to random whats inside the () as it will change from story to story. Later we hope to have it where the kids can enter their own parts of the story, showing action words etc, kind of a fun game.

[trq]

From the examples weve posted this should be easy. I'm sorry, but were not going to write it for you. If you don't understand it from here then I see little hope. Not to be harsh.... but I just can't see how we could explain things any clearer.

[BillyBoB]

ok look i will explain exactly what you should need:

 

for the first part the () words:

$words = array('word1','word2','word3');

 

ok now for the random part:

$selection = $words[rand(0,count($words)-1)];

 

tada now just take $selection and use it...

[per1os]

<?php
$text = "The (quick,slow) brown fox (hopped,jumped,leaped) over the (stubborn,stingy,nice) fence!";
if (eregi("\(([A-Z0-9,-_]*)\)", $text, $regs)) { // edited here to add the comma and hyphen and underscore.
       foreach ($regs as $match) {
            // unsure if the paran portion is included so lets replace them.
            $new_text = str_replace("\(", "", $match);
            $new_text = str_replace(")", "", $new_text); // this may need escaping the ( \) )
            $words = explode(",", $new_text);
            $new_text = "(" . $new_text . ")"; // add them back for replacing later.
            $selection = $words[rand(0,count($words)-1)];
            $text = str_replace($new_text, $selection, $text);
       }

      echo $text;
}
?>

 

That is the gist of it. I just coded it on the fly, no testing I am sure the regular expression is wrong, but for help with that look at http://www.zend.com/zend/spotlight/code-gallery-wade5.php and  http://www.regular-expressions.info/characters.html

 

Have fun!

[BillyBoB]

that would be a good way too...
