Hướng dẫn php str_replace multiple

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.

Like this:

str_replace[array[':', '\\', '/', '*'], ' ', $string];

Or, in modern PHP [anything from 5.4 onwards], the slighty less wordy:

str_replace[[':', '\\', '/', '*'], ' ', $string];

str_replace[] can take an array, so you could do:

$new_str = str_replace[str_split['\\/:*?"|'], ' ', $string];

Alternatively you could use preg_replace[]:

$new_str = preg_replace['~[\\\\/:*?"|]~', ' ', $string];

For example, if you want to replace search2 with replace1 and search2 with replace2 then following code will work:

print str_replace[
    array["search2","search2"],
    array["replace1", "replace2"],
    "search2 search2"
];

// Output: replace1 replace2

If you're only replacing single characters, you should use strtr[]

You could use preg_replace[]. The following example can be run using command line php:

Output:

$s2: "the string          "

I had a situation whereby I had to replace the HTML tags with two different replacement results.

$trades = "
Sprinkler and Fire      Protection Installer
Steamfitter 
Terrazzo, Tile and Marble      Setter
";

$s1 =  str_replace['
', '"', $trades];

$s2 = str_replace['
', '",', $s1];

echo $s2;

result

"Sprinkler and Fire Protection Installer", "Steamfitter ", "Terrazzo, Tile and Marble Setter",

I guess you are looking after this:

// 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.
