Best way to extract params from string

开发者 https://www.devze.com 2023-04-06 09:22 出处:网络
I have a name=\"value\" type string that looks like... {user type=\"active\" name=\"james green\" id=\"45\" group=\"active users\"}

I have a name="value" type string that looks like...

{user type="active" name="james green" id="45" group="active users"}

I need a generic function that will parse this type of string extracting all of the name/value pairs as an array from this format (always within double quot开发者_开发问答es and each param sepertated by a space, enclosed in {}) as well as the initial opening word (user in this case).

Any ideas would be much appreciated.


basically

 preg_match_all('~(\w+)="(.+?)"~', $string, $matches, PREG_SET_ORDER);
 foreach($matches as $m)
     $array[$m[1]] = $m[2]


$string = '{user type="active" name="james green" id="45" group="active users"}';
$user = simplexml_load_string('<' . substr($string, 1, -1) .'/>');
print_r(current($user));

will give

Array
(
    [type] => active
    [name] => james green
    [id] => 45
    [group] => active users
)

But that should be easy and more appropriate to solve with a Regex.


name "james green" can be extracted like this

<?php
    $point=strpos( $string, 'name="' ) + strlen('name="');
    $string = substr($string,$point);

    $point=strpos( $string, '"' );
    $string = substr($string,$point);

    echo $string; // james green
?>


$string = '{user type="active" name="james green" id="45" group="active users"}';
$string = str_replace('{', '', $string); // delete brackets
$array = explode(' ', $string);

$var = array_shift($array); // <-- here is 'user'

foreach($array as $pair)
{
$arr = explode('=', $pair);
$arr[0]; // <-- here is the key
$arr[1]; // <-- here is the value
}

Not tested!
