```
<?php
```
```
function lib_channel(&$ctag,&$refObj)
```
```
{
```
```

FillAttsDefault($ctag->CAttribute->Items,$attlist);

extract($ctag->CAttribute->Items, EXTR_SKIP);

```
$innertext = $ctag->GetInnerText();
```
```
$cacheid = trim($cacheid);
```
```
if($cacheid !='') {
```
```
$likeType = GetCacheBlock($cacheid);

```
}
