PHP正则表达式preg_match在url中分隔变量

Question

I have string

$string = 'foo/{id}/bar/{name}';

and I am trying to do regex filtering

wanted output:

$matches = [
  0 => 'foo/{id}/bar/{name}',
  1 => 'id',
  2 => 'name'
]

I got so far: (regex is my weakness)

preg_match('~^' . $magic . '$~', $string, $matches)

edit: there are *n number of {variable} in url

Answer 1

Use the following preg_match_all approach:

$str = 'foo/{id}/bar/{name}/many/{number}/of/{variables}';
preg_match_all('/\{([^{}]+)\}/', $str, $m);

print_r($m[1]);

The output:

Array
(
    [0] => id
    [1] => name
    [2] => number
    [3] => variables
)
