Str_replace for multiple items
提问by sameold
I remember doing this before, but can't find the code. I use str_replace to replace one character like this: str_replace(':', ' ', $string);
but I want to replace all the following characters \/:*?"<>|
, without doing a str_replace for each.
我记得以前这样做过,但找不到代码。我使用 str_replace 来替换这样的一个字符:str_replace(':', ' ', $string);
但我想替换以下所有字符\/:*?"<>|
,而不对每个字符进行 str_replace 。

Like this:
像这样:
str_replace(array(':', '\', '/', '*'), ' ', $string);
Or, in modern PHP (anything from 5.4 onwards), the slighty less wordy:
或者,在现代 PHP(从 5.4 开始的任何版本)中,稍微不那么冗长:
str_replace([':', '\', '/', '*'], ' ', $string);

str_replace()
can take an array, so you could do:
str_replace()
可以接受一个数组,所以你可以这样做:
$new_str = str_replace(str_split('\/:*?"<>|'), ' ', $string);
Alternatively you could use preg_replace()
:
或者,您可以使用preg_replace()
:
$new_str = preg_replace('~[\\/:*?"<>|]~', ' ', $string);

For example, if you want to replace search1 with replace1 and search2 with replace2 then following code will work:
例如,如果你想用 replace1 替换 search1,用 replace2 替换 search2,那么下面的代码将起作用:
print str_replace(
array("search1","search2"),
array("replace1", "replace2"),
"search1 search2"
);
// Output: replace1 replace2
// 输出:replace1replace2

You could use preg_replace(). The following example can be run using command line php:
您可以使用preg_replace()。可以使用命令行 php 运行以下示例:
<?php
$s1 = "the string \/:*?\"<>|";
$s2 = preg_replace("^[\\/:\*\?\"<>\|]^", " ", $s1) ;
echo "\n$s2: \"" . $s2 . "\"\n";
?>
Output:
输出:
$s2: "the string "
$s2: "字符串"

I had a situation whereby I had to replace the HTML tags with two different replacement results.
我遇到了一种情况,我不得不用两种不同的替换结果来替换 HTML 标签。
$trades = "<li>Sprinkler and Fire Protection Installer</li>
<li>Steamfitter </li>
<li>Terrazzo, Tile and Marble Setter</li>";
$s1 = str_replace('<li>', '"', $trades);
$s2 = str_replace('</li>', '",', $s1);
echo $s2;
result
结果
"Sprinkler and Fire Protection Installer", "Steamfitter ", "Terrazzo, Tile and Marble Setter",
“洒水喷头和防火安装工”、“Steamfitter”、“水磨石、瓷砖和大理石安装工”、

I guess you are looking after this:
我猜你正在照顾这个:
// example
private const TEMPLATE = __DIR__.'/Resources/{type}_{language}.json';
...
public function templateFor(string $type, string $language): string
{
return \str_replace(['{type}', '{language}'], [$type, $language], self::TEMPLATE);
}

In my use case, I parameterized some fields in an HTML document, and once I load these fields I match and replace them using the str_replace method.
在我的用例中,我参数化了 HTML 文档中的一些字段,一旦我加载了这些字段,我就会使用 str_replace 方法匹配和替换它们。
<?php echo str_replace(array("{{client_name}}", "{{client_testing}}"), array('client_company_name', 'test'), 'html_document'); ?>
