serialize ( variable[] )
serialize ( { x1, y1, x2, y2, x3, y3 ... } )

returns string_expression

The serialize statement creates a string that encodes the dimensions, types, and values in an array. The Unserialize function will take a “serialized” string and return an array or list.

Often developers will create a serialized string so that they may save the values in an array into a data file or a database table.

The string representing the array's data is a series of values separated by a colon ':'. The first value represents the number of rows and the second the number of columns. A one dimensional array will have a single row (1), with the length in the second value. The elements of the array follow. The first character of each value contains a marker byte defining the data type ('0'-unassigned, '1'-integer, '2'-float, and '3'-string). The actual array data follows. Strings are converted to hexadecimal so that any Unicode or special characters will be stored without change. The strings returned will contain ONLY ':', '.', '0'-'9', and 'a'-'f'.

The array {1,2,3,4,5.555,“six”} would be serialized to “1:6:11:12:13:14:25.555:3736978” and the array 1_2_3_4 would be serialized to “2:2:11:12:13:14”.
