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:

|"; $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.
