正则表达式似乎有效，但不起作用

Question

I'm tring to get a function to parse the data from the source of a website:

function parse ($source) {
$res = array();
$matches = array();
$rx = "#^\s*routes\.push\(\{'start':([a-zA-Z0-9':,\-\s]*),\s'finish':([a-zA-Z0-9':,\-\s]*),\s'[a-zA-Z0-9':,\-\s]*':([0-9\s\-]){1,4},[a-zA-Z0-9':,\.\-\s]*}\);\s*$#";
preg_match_all($rx, $source, $matches);
    for($i=0,$_i=count($matches[1]);$i<$_i;++$i) {
    $res[$i][0]=$matches[1][$i];
    $res[$i][1]=$matches[2][$i];
    }

The code to be parsed is like :

routes.push({'start': tokyo, 'finish': LA, 'blue': 18, 'arcoffset': -20, 'transpacific': true});
    routes.push({'start': tokyo, 'finish': seattle, 'blue': 6, 'arcoffset': 5, 'transpacific': true});
    routes.push({'start': tokyo, 'finish': sanjose, 'blue': 12, 'arcoffset': -4, 'transpacific': true});
    routes.push({'start': amsterdam, 'finish': tokyo, 'blue': 5, 'green': 2, 'arcoffset': 20});

The problem is that nothing goes in the arrays. And when I check the regexp by doing echo preg_match_all($rx, $page, $matches);

it returns 0 So there might be a problem with my regexp, but according to Regex Tester, it's OK:

Answer 1

您似乎想要匹配3件事：2个城市和1个数字。

$rx = "\{'start':([a-zA-Z]*),\s'finish':([a-zA-Z]*),\s'[a-zA-Z]*':\s([0-9\s\-]{1,4})";

Answer 2

用^ end $并说：整个字符串都与该模式匹配。.甚至没有重复..尝试删除它们，因此使您的模式如下所示：

$rx = "/\s*routes\.push\(\{'start':([a-zA-Z0-9':,\-\s]*),\s'finish':([a-zA-Z0-9':,\-\s]*),\s'[a-zA-Z0-9':,\-\s]*':([0-9\s\-]){1,4},[a-zA-Z0-9':,\.\-\s]*}\);\s*/";
