C# String.Format() Equivalent in PHP?
提问by Ben Griswold
I'm building a rather large Lucene.NET search expression. Is there a best practices way to do the string replacement in PHP? It doesn't have to be this way, but I'm hoping for something similar to the C# String.Format method.
我正在构建一个相当大的 Lucene.NET 搜索表达式。是否有最佳实践方法来在 PHP 中进行字符串替换？它不一定是这样，但我希望有类似于 C# String.Format 方法的东西。
Here's what the logic would look like in C#.
下面是 C# 中的逻辑。
var filter = "content:{0} title:{0}^4.0 path.title:{0}^4.0 description:{0} ...";
filter = String.Format(filter, "Cheese");
Is there a PHP5 equivalent?
有PHP5等价物吗？

You could use the sprintffunction:
您可以使用该sprintf功能：
$filter = "content:%1$s title:%1$s^4.0 path.title:%1$s^4.0 description:%1$s ...";
$filter = sprintf($filter, "Cheese");
Or you write your own function to replace the {i}by the corresponding argument:
或者您编写自己的函数来替换相应的参数：{i}
function format() {
$args = func_get_args();
if (count($args) == 0) {
return;
}
if (count($args) == 1) {
return $args[0];
}
$str = array_shift($args);
$str = preg_replace_callback('/\{(0|[1-9]\d*)\}/', create_function('$match', '$args = '.var_export($args, true).'; return isset($args[$match[1]]) ? $args[$match[1]] : $match[0];'), $str);
return $str;
}

Try sprintf http://php.net/sprintf

try this one if there is an error or 'create_function'
如果出现错误或“create_function”，请尝试此操作
public static function format()
{
$args = func_get_args();
$format = array_shift($args);
preg_match_all('/(?=\{)\{(\d+)\}(?!\})/', $format, $matches, PREG_OFFSET_CAPTURE);
$offset = 0;
foreach ($matches[1] as $data) {
$i = $data[0];
$format = substr_replace($format, @$args[$i], $offset + $data[1] - 1, 2 + strlen($i));
$offset += strlen(@$args[$i]) - 2 - strlen($i);
}
return $format;
}
