Joomla cache Jcache

joomla caches data through Jcache:

<code><span>//调用Cache，参数'com_campaign'为缓存组，必须!</span><span>$cache</span><span>=</span>   JFactory<span>::getCache</span>(<span>'com_campaign'</span>,<span>''</span>);
<span>//设置：即使关闭全局缓存时，此缓存仍有效</span><span>$cache</span><span>-></span>setCaching(<span>true</span>);
<span>//设置缓存时间,此处设置为 60s</span><span>$cache</span><span>-></span>setLifeTime(<span>60</span>);
<span>//获取缓存</span><span>$name</span><span>=</span><span>$cache</span><span>-></span>get(<span>'userid_101'</span>);
<span>if</span>(<span>!</span><span>$name</span>){
    <span>$str</span><span>=</span><span>'my name is cache'</span>;
    <span>//设置缓存</span><span>$cache</span><span>-></span>store(<span>$str</span>,<span>'userid_101'</span>);
}
echo <span>'<pre class="brush:php;toolbar:false">'</span>;print_r(<span>$name</span>);exit;
<span>//移除缓存</span><span>$cache</span><span>-></span>remove(<span>'userid_101'</span>);

<span>//获取全部缓存对象列表及简介</span><span>$cache</span><span>-></span>getAll();
<span>//清除缓存组。第二个参数为：group|notgroup 默认为group。notgroup不知道是干什么的</span><span>$cache</span><span>-></span>clean(<span>'com_campaign'</span>,<span>'group'</span>);
</code>

').addClass('pre-numbering').hide(); $(this).addClass('has-numbering').parent().append($numbering); for (i = 1; i ').text(i)); }; $numbering.fadeIn(1700); }); });

The above has introduced Joomla caching Jcache, including aspects of it. I hope it will be helpful to friends who are interested in PHP tutorials.
