Array ( [0] => Array ( [0] => Array ( [subject] => Computer [price] => 33.00 [quantity] => 1 ) ) )
I have an array like this above, but when i use in_array like below to check the subject value, it will display negative result.
foreach ($cart_info as $item){
foreach ($item as $item2){
if (in_array("Computer", $item2['subject'])) {
echo "Yes";
}else{
echo "No";
}
}
}
haystack Should be an array
Please check the documentation for in_array
bool in_array ( mixed $needle , array $haystack [, bool $strict = FALSE ] )
haystack
The array.
strict
If the third parameter strict is set to TRUE then the in_array() function will also check the types of the needle in the haystack.
You are passing a wrong key so you are not getting desired output.
it should be
in_array("Computer", $cart_info[0])
or
in_array("Computer", $cart_info)
or even
if($item2 == "Computer")
instead of
in_array("Computer", $item2['subject'])
try
if (in_array("Computer", $item2)) {
echo "Yes";
}else{
echo "No";
}
Because $item2['subject']
is not an array. In your case use:
foreach ($cart_info as $item){
foreach ($item as $item2){
if ("Computer" == $item2['subject'])) {
echo "Yes";
}else{
echo "No";
}
}
}
