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

str_replace(
    array("search","items"),
    array("replace", "items"),
    $string
);

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:

|";
$s2 = preg_replace("^[\\\\/:\*\?\"<>\|]^", " ", $s1) ;
echo "\n\$s2: \"" . $s2 . "\"\n";
?>

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.
