推荐答案

您的用法oh phantomjs根据文档是正确的. http://phantomjs.org/api/webpage/property/content.html

your usage oh phantomjs is correct according to the documentation. http://phantomjs.org/api/webpage/property/content.html

php exec方法仅返回最后一行. 也许那条线是空白. http://php.net/manual/fr/function.exec.php

php exec method returns the last line only. Maybe that line is a white space. http://php.net/manual/fr/function.exec.php

您应该有一个通过引用发送的第二个参数& $ output.这是一个包含整个输出的数组.

You shall have a seond parameter &$output, sent by reference. It is an array containing the entire output.

稍后可能会遇到的问题，在尝试读取DOM文档内容之前，可能需要对内容进行评估.例如，使用HTML标记的innerHTML，即:$('html').html();

A problem you may face later, the content could need be to evaluated before you try to read it s DOM document content. Using for example innerHTML of HTML tag, ie: $('html').html();

如果该页面没有jquery，则可以包含它，请参见以下示例，

If the page does not have jquery, you may include it, see this example, https://github.com/ariya/phantomjs/blob/master/examples/phantomwebintro.js

还请注意，Google可能会积极希望不要让用户抓取并保存他们的搜索结果.不确定.

Note also that google may actively desire to not let users scrap and save their search results. Not sure about that.
