I used PHP to post the code in API. I don’t know how to get data in ts file using subscribe (data). But in console network I have write output in JSON format.

home.ts

workerdailyreport(){
    return new Promise((reslove) => {
        let body = {
            aksi: 'update_workerdailyreport',
            full_nuts: this.x,

            rejected_nuts: this.z,
            id: this.id,
        };
        this.postPvdr.postData(body, 'proses-api.php').subscribe(data => {
            console.log(data);
            for (let passdata of data.result) {
                this.passdata.push(passdata);
            }
