i'have an array, and then i have a script who gets the category i'm browsing (using wordpress) and put it in the $category variable.
So i test if the category i'm browsing it's equal to the $array key and then i paste some text
$array = array ('key' => 'value', ... )
//...
// a script who gets the category i'm browsing and store it in the $category variable
//...
/* starting the foreach loop */
foreach( $array as $key => $value) {
if ($category == $key) {
echo "some $value here";
} elseif ($category !== $key) {
echo "nothing";
}
The problem is that this loop does echo "nothing" for each time the $category is not equal to the $key for each element of the array.
So if i have 20 key => value in the array this loop paste one time "some $value here" and 19 times "nothing"
there is a way to echo "nothing" only one time?
Thank you!
You can use array_key_exists
instead of the foreach
loop:
if (array_key_exists($category, $array)) {
echo $array[$category];
} else {
echo 'nothing';
}
$i=0;
foreach( $array as $key => $value) {
$i++;
if ($category == $key) {
echo "some $value here";
} elseif($category !== $key)
{
if($i<=1)
{
echo "nothing";
}
else{}
}
Try with -
$i = 1;
foreach( $array as $key => $value) {
if ($category == $key) {
echo "some $value here";
} elseif ($category !== $key) {
$i++;
}
}
if (count($array) == $i) {
echo "nothing";
}
