A lot of thinkphp beginners will encounter problems

A lot of video tutorials use $v.channel in the way that templates pass variables. For example, the following:

<a href= "{: U (' Chat/set ', array (' id ' = = $v. Channel)}" title= "Settings" class= "btn Btn-mini Tip" >

This causes the URL to fail at parse time. After the URL becomes id/arraychannel.html

In fact, in the TP manual variable output there, the array output in addition to using the above method can also be used in the following way:

$v [' channel ']

When we want to output a multidimensional array, we tend to use this way. In this way, there is no previous problem.
