在cakephp 3.0中显示Element时出现意外的回声

Question

I was trying to add Element in cakephp template page.

Documentation about Element in cakephp 3.0 says echo must be used.

echo $this->element('helloworld');

I follow documentation, but my website returns this error.

Error: syntax error, unexpected 'echo' (T_ECHO) 

When I don't use echo, it works fine. I tried directly:

$this->element('helloworld');

someone have any explanation about this error ? and where is my error ?

Answer 1

if you are doing this <?= $this->element('helloworld'); ?> then you don't need echo. However, if you are doing this <?php echo $this->element('helloworld');, then you need echo.

The difference is whether you are using php's echo short syntax. <?= vs <?php echo and it has nothing to do directly with CakePHP. It is just PHP... More info here: http://php.net/echo
