[英]How to add a space to the end of a string?
I searched online and found the str_pad() function but this is not what I need. 我在线搜索并找到了str_pad()函数,但这不是我所需要的。 I need to automatically add a space at the end of a string.
我需要在字符串的末尾自动添加一个空格。
The string value returned can be my default value or a custom value supplied by an extending developer. 返回的字符串值可以是我的默认值,也可以是扩展开发人员提供的自定义值。 If the developer supplies extra characters, which they can, then the
str_pad()
approach won't always work. 如果开发人员提供了多余的字符,那么
str_pad()
方法将永远无法工作。
Is there a simple function for this to ALWAYS add one space to the end of a string? 是否有一个简单的函数始终将一个空格添加到字符串的末尾? Like a
trim()
but works the opposite? 像
trim()
但效果相反?
Here is what I am doing. 这是我在做什么。
str_pad($this->filter('custom_hook_name', FALSE, 'column span-12'), 15);
My default is 'column span-12'
我的默认设置是
'column span-12'
However the developer might return their custom classes as well so the return string value could look something like... 但是,开发人员也可能返回其自定义类,因此返回字符串值可能类似于...
'dev-brand-column span-12'
'dev-brand-col col-12'
// etc...
I need to add a space as the end of the string regardless of the string length. 无论字符串的长度如何,我都需要在字符串的末尾添加一个空格。
How can I achieve that? 我该如何实现? I find nothing that works the opposite of trim() like.
我找不到与trim()相反的东西。
使用rtrim
首先删除可能存在的字符串末尾的所有空格,然后自己添加一个空格:
$str = rtrim($str) . " ";
I think that sprintf() can help you... 我认为sprintf()可以帮助您...
For example : 例如 :
$string = "Bond";
printf("%-10s", $string);
Will return : 将返回 :
Bond
With 6 spaces at the end of the string. 字符串末尾有6个空格。
Hope it helps. 希望能帮助到你。
