ciao
ho una funzione tramite la quale mostrare dei tag a rotazione, il problema è che li mostra tutti, come posso limitare il numero?
Codice PHP:<?php class wordCloud { var $version = '1.0'; var $wordsArray = array(); function __construct($words = false) { if ($words !== false && is_array($words)) { foreach ($words as $key => $value) { $this->addWord($value); } } } function wordCloud($words = false) { $this->__construct($words); } function addWord($word, $value = 1) { $word = strtolower($word); if (array_key_exists($word, $this->wordsArray)) $this->wordsArray[$word] += $value; else $this->wordsArray[$word] = $value; return $this->wordsArray[$word]; } function shuffleCloud() { $keys = array_keys($this->wordsArray); shuffle($keys); if (count($keys) && is_array($keys)) { $tmpArray = $this->wordsArray; $this->wordsArray = array(); foreach ($keys as $key => $value) $this->wordsArray[$value] = $tmpArray[$value]; } } function getCloudSize() { return array_sum($this->wordsArray); } function getClassFromPercent($percent) { if ($percent >= 99) $class = 1; else if ($percent >= 70) $class = 2; else if ($percent >= 60) $class = 3; else if ($percent >= 50) $class = 4; else if ($percent >= 40) $class = 5; else if ($percent >= 30) $class = 6; else if ($percent >= 20) $class = 7; else if ($percent >= 10) $class = 8; else if ($percent >= 5) $class = 9; else $class = 0; return $class; } function showCloud($returnType = "html") { $this->shuffleCloud(); $this->max = max($this->wordsArray); if (is_array($this->wordsArray)) { $return = ($returnType == "html" ? "" : ($returnType == "array" ? array() : "")); foreach ($this->wordsArray as $word => $popularity) { $sizeRange = $this->getClassFromPercent(($popularity / $this->max) * 100); if ($returnType == "array") { $return[$word]['word'] = $word; $return[$word]['sizeRange'] = $sizeRange; } else if ($returnType == "html") { $return .= "<span class='word size{$sizeRange}'> {$word} </span>"; } } return $return; } } } ?>
