Regular text replacement method for php, js, and java to produce template content output_PHP tutorial

When making template content output, placeholders such as <%=%> are often used. It is very convenient to replace this content with regular methods. In my work, I only come into contact with java, php, and js, three languages ​​​​Simple implementation:

java version

import java.util.HashMap;

import java.util.Map;

import java.util.regex.Matcher;

import java.util.regex.Pattern;

public class TestRex {

public static void main(String[] args) {

Map map = new HashMap();

map.put("name", "penngo");

map.put("date", "2013-01-17");

Pattern p = Pattern.compile("<%=(\w+?)%>");

String str = "<%=date%>, Hello <%=name%>";

Matcher m = p.matcher(str);

StringBuffer sb = new StringBuffer();

boolean result = m.find();

while (result) {

String key = m.group(1);

String value = map.get(key);

m.appendReplacement(sb, value);

result = m.find();

}

m.appendTail(sb);

System.out.println(sb.toString());

}

}

php version

$data = array('name'=>'penngo', 'date'=>'2013-01-17');

function replaceStr($key, $data){

return $data[$key];

}

$str = '<%=date%>, Hello <%=name%>';

$str = preg_replace("/<%=(w+?)%>/ise", "replaceStr('\1', $data)", $str);

echo $str;

?>

js version

Run result output:

2013-01-17, Hello penngo
