int count (mixed $var [, int $mode])-- calculates the number of cells in an array or the number of attributes in an object

If the optional mode parameter is set to Count_recursive (or 1), COUNT () counts recursively on the array. is especially useful for calculating all cells of a multidimensional array. The default value for mode is 0. Count () does not recognize infinite recursion.


if ( count ( $array ) ==  count ( $array , 1)) {      echo ‘是一维数组‘ ; else {      echo ‘不是一维数组‘ ; }
