Hi,
Does anyone have a clue why I get the following error in my further following code ?
Notice: Use of undefined constant RETURNTRANSFER - assumed 'RETURNTRANSFER' in C:\xampp\htdocs\test\curl.php on line 27
Warning: curl_setopt() expects parameter 2 to be integer, string given in C:\xampp\htdocs\test\curl.php on line 27
You are welcome to rectify the code where I'm goign wrong and then show me how it should have been.
I actually, copied this from a youtube tutorial and they don;t get any errors but I do! Absurd! I copied it while I was learning the basics of cURL.
<?php
// Youtube Channel: Clever Techie; Video: PHP cURL Tutorial - Learn PHP Programming.
// 1). Create cURL resource.
$curl = curl_init();
// 2). Set cURL options.
curl_setopt($curl, CURLOPT_URL, 'http://www.google.com');
// 3). Run cURL (execute http request).
curl_exec($curl);
// 4). Close cURL resource.
curl_close($curl);
// 1). $curl is going to be data type curl resource.
$curl = curl_init();
$search_string = "movies 2017";
$url = "https://www.amazon.com/s/field-keywords=$search_string";
// 2). Set cURL options.
curl_setopt($curl, CURLOPT_URL, 'https://www.amazon.com');
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, RETURNTRANSFER, true);
// 3). Run cURL (execute http request).
$result = curl_exec($curl);
preg_match_all("!https://images-na.ssl-images-amazon.com/images/I/[^\s]*?._AC_US_160_.jpg!, $result, $matches");
//Use either one of the following 4 codes. (Use one by one in order to test and learn).
//code 1:
print_r($matches);
//code 2:
$images = array_unique($matches[0]);
print_r($images);
//code 3:
$images = array_values(array_unique($matches[0]));
print_r($images);
//code 4:
$images = array_values(array_unique($matches[0]));
for ($i = 0; $i < count ($images); $i++) {
echo "<div style='float:left; margin: 10 0 0 0; '>";
echo "img src='$images[$i]'><br />";
echo "</div>";
}
// 4). Close cURL resource.
curl_close($curl);
?>
