I encountered a problem today. When assigning a value to a member variable in a class, I kept getting an error. It is a constant connected to a string

<code><span><span>class</span><span>FileUploadController</span><span>extends</span><span>Controller</span>{</span><span>private</span><span>$path</span> = BASEDIR.<span>"/Public/Upload"</span>;           <span>//<strong>上传文件</strong>保存你路径</span><span>private</span><span>$allowType</span> = <span>array</span>(<span>'jpg'</span>,<span>'png'</span>,<span>'gif'</span>);          <span>//文件限制格式</span></code>

If the original member variable contains a constant or variable, and the connected string must assign a value to the member variable through the construction method, otherwise the constant will not be visible in the class

<code><span>public</span><span><span>function</span><span>__construct</span><span>()</span>{</span><span>$this</span>->path = <span>__DIR__</span>.<span>"/Public/Upload"</span>;
    }</code>

If it only contains constants, there is no need to construct it Method

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

The above introduces the error reporting using connectors for PHP member variable assignment, including the content of uploading files. I hope it will be helpful to friends who are interested in PHP tutorials.
