Getting Data from CokeBikes

Just a piece of PHP for getting data from www.bikeshare.ie. it is in a JSON format at the top of the webpage in JavaScript, I get it out of the webpage using a Regex and then pass it through a JSON decoder in PHP to get the piece I want.

<?php

$ch = curl_init("https://www.bikeshare.ie/cork.html");

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$htmlData = curl_exec($ch);
curl_close($ch);


//echo $htmlData;


$pattern = '/{\"\s*([^\n\r]*)}]};/';


preg_match($pattern, $htmlData, $matches);

$rest = substr($matches[0], 0, -1);

$json = json_decode($rest,true);

# check if there has been an error decoding:
if (! isset($json)) {
    echo "Decoding error: " . json_last_error_msg() . PHP_EOL;
}


echo $json['cork'][0]["name"];
echo ", \n";

echo $json['cork'][0]["bikesAvailable"];
echo "\n";

?>

<?php

$ch = curl_init("https://www.bikeshare.ie/cork.html");

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$htmlData = curl_exec($ch);

curl_close($ch);

//echo $htmlData;

$pattern = '/{\"\s*([^\n\r]*)}]};/';

preg_match($pattern, $htmlData, $matches);

$rest = substr($matches[0], 0, -1);

$json = json_decode($rest,true);

# check if there has been an error decoding:

if (! isset($json)) {

echo "Decoding error: " . json_last_error_msg() . PHP_EOL;

}

echo $json['cork'][0]["name"];

echo ", \n";

echo $json['cork'][0]["bikesAvailable"];

echo "\n";
