Ideas in this flowchart

PHP supports foreach loops for iterating over array elements.
The loop uses the keyword foreach.
The discussion previews Section 42, which covers arrays in PHP.
A foreach loop iterates over the elements of an array.
Example: $arr is initialized with the values 1.41, 2.71, and 3.14.
The syntax foreach($arr as $x) assigns each current element to $x.
PHP also supports associative arrays.
Associative arrays are different from traditional arrays.

"Finally, PHP supports foreach loops using the keyword foreach. Some of this will be a preview of Section 42 where we discuss arrays in PHP. In short you can iterate over the elements of an array as follows.\n\n$arr = array(1.41, 2.71, 3.14);\n\nforeach($arr as $x) {\n\n//x now holds the \"current\" element in arr\n\nActually, PHP supports associative arrays, which are not the same thing as traditional arrays."
