How to create a string with x numbers of the same character without looping in PHP

Question

Is there a nice way (without looping) to create a string constructed by a number of the same characters?

Eg I know I should add 5 '.' to the beginning of a string. How do I do that without looping?

I don't know beforehand that it should be 5 '.', that can vary. Hence my question.

I'm using PHP.

Answer 1

尝试使用str_repeat ：

$output = str_repeat(".", 5); // .....

Answer 2

Use the str_repeat() function. For example, to concatenate 5 dots together without using a loop, you could do this:

$fiveDots = str_repeat('.', 5);

Answer 3

Yes, there is.

Answer 4

使用str_pad（）函数......就这么简单。
