PHP vérifie si la variable est un nombre entier

Question

J'ai ce code PHP :

$entityElementCount = (-($highScore-$totalKeywordCount))/0.29;

Ce que je veux savoir, c'est comment vérifier si $entityElementCount est un nombre entier (2, 6, ...) ou partiel (2,33, 6,2, ...).

Merci !

Answer 1

$entityElementCount = (-($highScore-$totalKeywordCount))/0.29;

Method 1-
    By using ctype_digit() function. 

    if ( ctype_digit($entityElementCount )) { 
        echo "Whole Number\n"; 
    } else { 
        echo "Not a whole Number\n"; 
    } 

Method 2-
    By using is_float() function. 

    if (is_float($entityElementCount )) { 
        echo "Not a Whole Number\n"; 
    } else { 
        echo "Whole Number\n"; 
    } 

Method 3-
    By using is_int() function. 

    if (is_int($entityElementCount )) { 
        echo "Whole Number\n"; 
    } else { 
        echo "Not a whole Number\n"; 
    } 

Method 5-
    By using fmod() function. 

    It needs 2 parameters one dividend and other is divisor
    Here $dividend=$entityElementCount and divisor=1
    if (fmod($dividend,$divisor) !== 0.0) {
        echo 'Not a whole number!';
    } else {
     echo 'A whole number!';
    }

there are some more function like intval(), floor(),... can be used to check it`enter code here`
