PHP needs to end the instruction with a semicolon after each statement.An end tag in a PHP code implies a semicolon; the last line in a PHP snippet can end without a semicolon.If there are new rows later, the end tag of the snippet contains the end of the line.The end tag of the PHP snippet at the end of the file can be omitted, and in some cases it would be better to omit it when using include or require-avoid unnecessary whitespace characters.PHP Manual

1.Array arraysThe array in PHP is actually an ordered map. A map is a type that associates values to the keys. This type is optimized in many ways, so it can be used as a real array, or as a list (vector), a hash (an implementation of a mapping), a dictionary, a collection, a stack, a queue, and more possibilities. Because the value of an array element can also be another array, the tree structure and the multidimensional array are also allowed.Explaining these structures is beyond the scope of
