在 PHP5 中用多个/不同的值搜索和替换多个值?

问题描述

是否有一个内置的 PHP 函数可以将字符串中的多个值替换为一个数组，该数组指示什么被替换为什么?

Is there an inbuilt PHP function to replace multiple values inside a string with an array that dictates exactly what is replaced with what?

例如:

$searchreplace_array = Array('blah' => 'bleh', 'blarh' => 'blerh');
$string = 'blah blarh bleh bleh blarh';

结果将是:'bleh bleh bleh bleh bleh'.

And the resulting would be: 'bleh blerh bleh bleh blerh'.

推荐答案

您正在寻找 str_replace().

You are looking for str_replace().

$string = 'blah blarh bleh bleh blarh';
$result = str_replace(
  array('blah', 'blarh'), 
  array('bleh', 'blerh'), 
  $string
);

//附加提示:

如果您像示例中那样使用关联数组，您可以将其拆分如下:

And if you are stuck with an associative array like in your example, you can split it up like that:

$searchReplaceArray = array(
  'blah' => 'bleh', 
  'blarh' => 'blerh'
);
$result = str_replace(
  array_keys($searchReplaceArray), 
  array_values($searchReplaceArray), 
  $string
);
