I wrote a program to define an associative array titled $aFilter and tried to print it but I'm not able to. I tried two ways to achieve this but couldn't succeed. Following are the two ways I tried.
Way 1:
<!DOCTYPE html>
<html>
<body>
<?php
$aFilter = Array
(
['pages'] => 1,
['photo'] => 1,
['link'] => 1,
['event'] => 1,
['friend'] => 1,
['user_status'] => 1,
['poll'] => 1,
['quiz'] => 1,
['market'] => 1,
['apps'] => 1
)
print_r($aFilter);
?>
</body>
</html>
Way 2:
<!DOCTYPE html>
<html>
<body>
<?php
$aFilter = Array
(
['pages'] => 1
['photo'] => 1
['link'] => 1
['event'] => 1
['friend'] => 1
['user_status'] => 1
['poll'] => 1
['quiz'] => 1
['market'] => 1
['apps'] => 1
)
print_r($aFilter);
?>
</body>
</html>
After executing both of the above codes I'm getting blank white screen. No any error or warning. Why so happens? How can I get errors and warnings displayed on my webpage without making any change to php.ini file settings?
Can someone please correct the mistake I'm making and help me?
You forgot an ; after defining the array. And also don't use [] when defining an array. More info on array's.
$aFilter = Array(
'pages' => 1,
'photo' => 1,
'link' => 1,
'event' => 1,
'friend' => 1,
'user_status' => 1,
'poll' => 1,
'quiz' => 1,
'market' => 1,
'apps' => 1
);
print_r($aFilter);
print_r() displays information about a variable in a way that's readable by humans. It is not the code you need to write.
Both ways are missing the ; after the array definition and Way 2 is missing ,s after each array element. Also, both ways should use 'elName' => 'elValue', instead of ['elName'] => 'elValue',
The problem are:-
So write in this way:-
$aFilter = Array(
'pages' => 1,
'photo' => 1,
'link' => 1,
'event' => 1,
'friend' => 1,
'user_status' => 1,
'poll' => 1,
'quiz' => 1,
'market' => 1,
'apps' => 1
);
print_r($aFilter);
