php repeat function 10 times if value is comma - php

Question

I'm trying to repeat the function only if the value is ",":
This is my code for trying to get the coordinates from an address but somtimes it gets only "," so I want it to try 10 times until it gets the full coordinates.
$coordinates1 = getCoordinates($placeadress);
$i == 0;
while (($coordinates1 == ',') && ($i <= 10)) {
$coordinates1 = getCoordinates($placeadress);
$i++;
}
The function code is this:
function getCoordinates($address) {
$address = str_replace(" ", "+", $address); // replace all the white space with "+" sign to match with google search pattern
$address = str_replace("-", "+", $address); // replace all the "-" with "+" sign to match with google search pattern
$url = "http://maps.google.com/maps/api/geocode/json?address=$address";
$response = file_get_contents($url);
$json = json_decode($response,TRUE); //generate array object from the response from the web
return ($json['results'][0]['geometry']['location']['lat'].",".$json['results'][0]['geometry']['location']['lng']);
}

Answer 1

May be try this
$coordinates1 = getCoordinates($placeadress);
$i = 0;
while ($i <= 10) {
$coordinates1 = getCoordinates($placeadress);
if($coordinates1==',')
$i++;
else
break;
}
It will break the loop as soon as co-ordinates value is not a comma and you are good to go. If it is a comma it will go for next iteration in while

Answer 2

You could just reduce all that code to a while with an empty block:
<?php
$i = 0;
while (
($coords = getLatLong($place))
&& $coords == ','
&& $i++ < 10
);
There's still perhaps no guarantee of the 'right' value being returned even after calling the function 10 times.
