Überprüfen Sie, ob alle Werte im Array gleich PHP sind
if(count(array_unique($array)) === 1) {
// all values in $array are the same
} else {
// at least 1 value in $array is different
}
if(count(array_unique($array)) === 1) {
// all values in $array are the same
} else {
// at least 1 value in $array is different
}$a=["a","b","c","d","e"];
$b=["d","e","f","g"];
$inBothAndB = array_intersect($a, $b); // Array([3] => d [4] => e) // All values are equal
if (count(array_unique($allvalues)) === 1 && end($allvalues) === 'true') {
}
// Check the thing you don't want
if (in_array('false', $allvalues, true)) {
}$allvalues = array('true', 'true', 'true');
if (count(array_unique($allvalues)) === 1 && end($allvalues) === 'true') {
}1. Check if all values are equal without knowing the values from array:
$array = array('true', 'true', 'true');
if((count(array_unique($array)) === 1)) {
echo "all equal";
} else {
echo "not equal";
}
2. Check if all values are equal when you know the value from array:
- In this case we know the equal value should be "true"
$array = array('true', 'true', 'true');
if (count(array_unique($array)) === 1 && end($array) === 'true') {
}if(count(array_unique($array, SORT_REGULAR)) < count($array)) {
// $array has duplicates
} else {
// $array does not have duplicates
}
