It prints on the screen when it is correctly entered, but I do not want to do anything when it is entered incorrectly
How can I do that?
<?php
header('Content-type: text/html; charset=utf8');
$api_key = 'local';
$keyword = 'test';
$url = 'test.json' . $api_key . '&' .'keyword' .'=' . $GLOBALS['q'] ;
$open = file_get_contents($url);
$data = json_decode($open, true);
$istatistikler = $data['data'];
if ($data) {
foreach ( $istatistikler as $istatistik ){
echo '<div class="right">';
echo 'Oyun modu: ' . $istatistik['title'] . '<br />' .
'Kazanma: ' . $istatistik['content'] . '<br />' .
'Kazanma: ' . $istatistik['image'] . '<br />' .
'Kazanma: ' . $istatistik['category'] . '<br />' .
'<br />' .
'<hr/>';
$karakter_simge = 'http://google.com' . $istatistik['image'] . '';
echo "<img src=".$karakter_simge." >" ;
echo '</div>';
}
}
?>
Successful output

thank you for your help!

Answer 1

This may be helpful:
$open = #file_get_contents($url);
# sign before a function name (in a call) prevents from showing any warnings (It's a bad practice though).
Good luck!

Answer 2

Change
$open = file_get_contents($url);
into
$open = #file_get_contents($url);
if ($open === false)
die("wrong");
The # suppresses the error message. Using die() will abort the script completely with the given message.
Alternatively, change the condition to !== false and wrap the rest of your "successful" code in its body:
$open = #file_get_contents($url);
if ($open !== false)
{
$data = json_decode...
...
...
}
I guess I overshot the goal here a little, but not even running into code that won't work properly without its data isn't a bad idea at all.
