Description
The FOREACH...ENDFOR command is used to iterate over each element in an array or member in an object. The <array> must be the name of an existing array or object. The <value> is a reference to be loaded with the contents of each element or member in turn. Using the <key> => <value> syntax, the member names of an object or associative array can also be accessed.
Example
numbers = array(1,2,3,4,5,6,7,8,9,10) foreach numbers as elem ? elem * elem endfor // associative array private myarray = array("Name" => "Lianja", "Description" => "database") foreach myarray as key => value echo "key=" + key + " value=" + value + "\n" endfor
