Preg_match从Html中提取Json

Question

$ data（HTML Response）：

...
<script type="text/javascript">
//<![CDATA[
WebForm_AutoFocus('drpDwnLstLinhas');Sys.Application.add_init(function() {
$create(Artem.Google.MarkersBehavior, {"markerOptions":..EXTENSIVE JSON..,"name":"map_GoogleMarkers"}, null, null, $get("map"));
});
//]]>
</script>
...

我想提取：{"markerOptions":..EXTENSIVE JSON..,"name":"map_GoogleMarkers"}

代码：

preg_match('~$create(Artem.Google.MarkersBehavior, (.*?), null, null, $get("map"));~', $data, $json);
var_dump($json); //empty

Answer 1

你只需要逃避“$”和“（”和“）”

preg_match('~\$create\(Artem.Google.MarkersBehavior, (.*), null, null, \$get\("map"\)\);~', $data, $json);

测试。
