[英]Heredoc <<< or <<?
Well I am wondering what is the right way to do the Heredoc syntax? 好吧,我想知道执行Heredoc语法的正确方法是什么?
In my code editor, which is 'e-text editor' doing <<<
totally throws off the syntax highlighting. 在我的代码编辑器中,做为<<<
“电子文本编辑器”完全使语法突出显示不起作用。
and doing << instead doesn't. 而不是<<。
code: 码:
private function buildDB() {
// build database
$sql = <<<MySQL_QUERY
CREATE TABLE IF NOT EXISTS testDB (
title VARCHAR(150),
bodytext TEXT,
created VARCHAR(100);
)
MYSQL_QUERY;
return mysql_query($sql);
}
Which is the right way? 哪种方法正确? I am still very noobish so no idea. 我还是很笨拙,所以不知道。
or maybe I shouldn't rely on syntax highlighting eh? 还是我不应该依赖语法高亮显示? :/ :/
Take a look at example 2: http://php.net/manual/en/language.types.string.php 看一下示例2: http : //php.net/manual/en/language.types.string.php
It is <<<
<<<
You need to put the ending MYSQL;
您需要放入结尾的MYSQL;
on the beginning of the line without any whitespace. 在行的开头没有任何空格。 That's why your editor won't highlight it correctly. 这就是为什么您的编辑器无法正确突出显示它的原因。
The closing of the HEREDOC string most be on a new line without spaces before it , so MYSQL_QUERY;
HEREDOC字符串的结尾大部分在换行符之前 , MYSQL_QUERY;
没有空格 ,因此为MYSQL_QUERY;
must be at the start of the line, without whitespace before or after. 必须在行的开头,前后不得有空格。
