stupid question I know, but I need fresh eyes as I cannot see the error. My code is this : $element = $this->domDocument->getElementByTagName("Team"); for ($i =0 ; $i < $element.length ; $i ++ ) { print $element[$i].childNodes[0].nodeValue; } and the error is : PHP Parse error: syntax error, unexpected '[' on line 40 which is the line with the print statem
我知道这个愚蠢的问题,但我需要新鲜的眼睛,因为我看不到错误。 我的代码是这样的: $element = $this->domDocument->getElementByTagName("Team"); for ($i =0 ; $i < $element.length ; $i ++ ) { print $element[$i].childNodes[0].nodeValue; } 错误是: PHP Parse error: syntax error, unexpected '[' on line 40 这是打印语句的行。 你能发现什么是错的吗? $element = $thi

I'm a n00b tying to get my head around the operator syntax. I understand it's called the object operator and I can see how it's used (Where do we use the object operator "->" in PHP?) by itself. I'm trying to learn what the purpose is when they are strung together like in this snippet (eg "switch($this->request->param('id')): here's a snipp
我是一个试图让我的头在操作符语法上的人。 我知道它被称为对象操作符,我可以看到它是如何使用的(我们在PHP中使用对象操作符“ - >”的位置)。 我试图了解当它们串在一起时的目的是什么(例如“switch($ this-> request-> param('id')): 这里是使用Kohana的站点代码片段: public function action_list() { $connections = ORM::factory('Connection') ->with('property') -&

Whenenever I'm discussing PHP with colleagues I don't know how to describe the little arrow symbol '->' used for accessing properties and methods in PHP. Does it have a name? Is it called arrow? I mostly call it object access operator. EDIT: Actually, come to think of it; I usually pronounce it as "dot", since most of us here are more familiar with the dot-nota
每当我与同事讨论PHP时,我都不知道如何描述用于访问PHP中的属性和方法的小箭头符号' - >'。 它有名字吗? 它被称为箭头吗? 我大多称之为对象访问操作符。 编辑:其实,想到它; 我通常会将其声明为“点”,因为我们大多数人都更熟悉访问对象属性的点符号。 由于它显然不是一个点,这可能不是你正在寻找的答案。 链接运算符,请阅读:http://en.wikipedia.org/wiki/Method_chaining 它被称为箭头运算符 尽
