It is necessary in PHP code where there is a js code to output, for example, through an alert variable. Does not work. Please help, tell me how to do it. And if anyone can how to use this as a URL to the picture.

function setLocation($url_image){
   $locationName = R::load('locationsdb', $url_image);
    echo '';
    
}

alert("{"id":"3","location_name":"\u0410\u043b\u0445\u0438\u043c\u0438\u043a\r\n","location_description":"\u0423 \u044d\u0442\u043e\u0433\u043e \u0441\u0442\u0430\u0440\u0446\u0430 \u043c\u043e\u0436\u043d\u043e \u043f\u0440\u0435\u043e\u0431\u0440\u0435\u0441\u0442\u0438 \u043d\u0430\u0441\u0442\u043e\u0439\u043a\u0438, \u0441\u043f\u043e\u0441\u043e\u0431\u043d\u044b\u0435 \u043f\u0440\u0438\u0434\u0430\u0432\u0430\u0442\u044c \u0441\u0438\u043b \u0433\u0435\u0440\u043e\u044f\u043c, \u0438\u0441\u0446\u0435\u043b\u044f\u0442\u044c \u0438\u0445 \u043f\u043e\u0441\u043b\u0435 \u043e\u0436\u0435\u0441\u0442\u043e\u0447\u0435\u043d\u043d\u044b\u0445 \u0431\u043e\u0435\u0432 \u0438 \u043c\u043d\u043e\u0435 \u0434\u0440\u0443\u0433\u043e\u0435, \u0447\u0442\u043e \u043c\u043e\u0436\u0435\u0442 \u0441\u0438\u043b\u044c\u043d\u043e \u043f\u043e\u043c\u043e\u0447\u044c \u0432 \u0442\u044f\u0436\u043a\u043e\u0439 \u0436\u0438\u0437\u043d\u0438 \u0438\u0441\u043a\u0430\u0442\u0435\u043b\u044f \u043f\u0440\u0438\u043a\u043b\u044e\u0447\u0435\u043d\u0438\u0439.\r\n","location_travel":"2","location_lut":"-","location_mobs":"-","location_image":"../images/locationsBackgrounds/backgroundAlchemistImage.png","location_runs":"-","location_characters":"-"}");
