Regarding php arrays, how to display the characters of the element itself?
$data[‘a’]=1;
$data[‘b’]=2;
$data[‘c’]=3;
I Want to display:
a
b
c
It is not to display the value of the element, but to display the characters of the element itself
——Solution——————–
Are you talking about key?
$data=array(‘a’=>1,’b’=>2,’c’=>3);
foreach ($data as $key=>$value){
echo $key;
}
Is it key? Or what does it mean.
