Echo vs Print [英] Echo vs Print

问题描述

我只是想知道为什么大多数人都会使用回声而不是打印。我/ b $ b $倾向于使用打印，可能是因为我开始在BASIC中编程，然后回到
78，所以它只是熟悉。


Echo可以采用多个表达式（如echo

$ string1，$ string2，$ string3），这显然比多个表达快一点

连接。但对于基本输出，似乎没有明显的

差异。 http://dynacker.dotgeek.org/printvsecho/ 上的速度测试显示

a" 5％"速度差异，但这相当于典型脚本上实际执行时间的微小差异。


所以 - 为什么选择回声？ overprint，反之亦然？

I''m just wondering why it seems most people use "echo" instead of "print". I
tend to use "print", probably because I started programming in BASIC back in
78, so it''s just familiar.

Echo can take multiple expressions (as in "echo
$string1,$string2,$string3"), which apparently is a bit faster than multiple
concatenations. But for basic output, there doesn''t seem to be a noticeable
difference. The speed test at http://dynacker.dotgeek.org/printvsecho/ shows
a "5%" difference in speed, but this amounts to a negligible difference in
actual execution time on a typical script.

So - why does one choose "echo" over "print", or vice-versa?
