PHP preg_replace was rewritten with c#. The PHP language is very powerful, mainly because of its powerful functions to support. In this article, we’ll explain how to use the PHP function preg_replace() in more detail. Preg_replace () preg_replace(mixed $pattern, mixed $replacement, mixed $subject [, int $limit]) The PHP function preg_replace() is more powerful than c. The first three parameters can be used array; The fourth parameter, $limit, allows you to set the number of substitutions, and by default, all substitutions. Code 6.7 is an example of an array substitution application. PHP function preg_replace() code 6.7 array replacement

< ?php
//string
$string = "Name: {Name}< br>nEmail:
{Email}< br>nAddress: {Address}< br>n";
//model
$patterns =array(
"/{Address}/",
"/{Name}/",
"/{Email}/"
);
//Replacement string
$replacements = array (
"No.5, Wilson St., New York, U.S.A",
"Thomas Ching",
"[email protected]",
);
//Output mode replacement results
print preg_replace($patterns,
$replacements, $string);
?>

The output is as follows. Name: Thomas Ching ”, Email: tomaddress.com Address: No. 5, Wilson st., New York, U.S.A C #

public static String PregReplace(this String input, string[] pattern, string[] replacements) {
if (replacements.Length != pattern.Length) throw new ArgumentException("Replacement and Pattern Arrays must be balanced");
for (var i = 0; i < pattern.Length; i++)
{ input = Regex.Replace(input, pattern[i], replacements[i]); }
return input;
}
