在 Lavavel 6 中替换字符串中给定值的所有匹配项
1、现在有一个字符串，其内容如下
1 | The event will take place between default and default |
2、期望将字符串中的 default 批量替换为 Basic
3、参考 Str::replaceArray 函数使用数组顺序替换字符串中的给定值
1 2 3 4 5 | $string = 'The event will take place between default and default';$replaced = Str::replaceArray('default', ['Basic'], $string);var_dump($replaced);exit; |
4、由于数组 $replace 中仅包含一个元素，最终仅替换了一个 default。如图1
图1
1 | string(51) "The event will take place between Basic and default" |
5、参考 Str::replaceArray 函数，修改为如下实现
1 2 3 4 5 6 7 8 9 10 11 | $string = 'The event will take place between default and default';$search = 'default';$replace = 'Basic';$segments = explode($search, $string);$result = array_shift($segments);foreach ($segments as $segment) { $result .= $replace . $segment;}var_dump($result);exit; |
6、字符串中的 default 全部被替换为 Basic。如图2
图2
1 | string(49) "The event will take place between Basic and Basic" |
