php中理解print EOT分界符和echo EOT的用法区别小结
html与php编写中echo可以同时输出多个字符串,并不需要圆括号。
print只可以同时输出一个字符串,需要圆括号。
print的用法和C语言很像,所以会对输出内容里的%做特殊解释。
echo无返回值,print()有返回值,当其执行失败(比如断线)时返回flase 。
echo可以多个参数,print一个参数。推荐用echo。
看下面的例子就能明白php中print
复制代码 代码如下:
print
$value;

...
EOT;
含义:
EOT 自定义分界符,结束时必须位于行首;
在同一页面中使用标记;
注:标记名为配对出现,同一页面中不允许同名出现两个以上标记名;
另:配对标记名的结尾标记名应单独一行,前后均不允许输出字符...(例如空格等不可见但存在的字符..)。
优点:这样可以输出大段的HTML 而且不用把里面的引号转义 就是不用 \" 这样自动替换里面的变量。

Coin Standard and U-Material Perpetual Contract: Conversion and risk analysis of leverage multiples. The pricing methods of perpetual contracts are mainly divided into two types: coin Standard and U-Material.
