In php, arrays are divided into one-dimensional arrays and multi-dimensional arrays. if we want to loop through two-dimensional arrays, we can directly use foreach and for traversal, next I will introduce you to the implementation of several two-dimensional array loops. if you need to know about them, please refer.
For loop traversal of two-dimensional array
| The code is as follows: |
|
Print_r ($ order_data_info ); Array ( [0] => stdClass Object ([countOrder] => 3 [amntTotal] => 2380.00 [name] => test version) [1] => stdClass Object ([countOrder] => 1 [amntTotal] => 2380.00 [name] => VIP Edition) [2] => stdClass Object ([countOrder] => 2 [amntTotal] => 4760.00 [name] => Personal Edition) ) $ Order_length = sizeof ($ order_data_info ); For ($ I = 0; $ I <$ order_length; ++ $ I) { $ Order_data_info [$ I]-> amntTotal = money ($ order_data_info [$ I]-> amntTotal ); }
Print_r ($ order_data_info ); Array ( [0] => Array ([countOrder] => 3 [amntTotal] => 2380.00 [name] => test version) [1] => Array ([countOrder] => 1 [amntTotal] => 2380.00 [name] => VIP Edition) [2] => Array ([countOrder] => 2 [amntTotal] => 4760.00 [name] => Personal Edition) ) $ Order_length = sizeof ($ order_data_info ); For ($ I = 0; $ I <$ order_length; ++ $ I) { $ Order_data_info [$ I] ['amnttotal'] = money ($ order_data_info [$ I] ['amnttotal']); } |
The foreach statement is used to traverse arrays cyclically.
Each cycle is performed, the value of the current array element is assigned to the value variable (the array pointer is moved one by one)-and so on
| The code is as follows: |
|
Foreach ($ array as $ key) { If (xxxx) { Break; // The break terminates the loop. } If (zzz) { Continue; // continue terminates this loop and enters the next loop at the moment; } } |
Example
| The code is as follows: |
|
$ Team = array ('LK ',' OK '); $ Book = array ('Linux server configuration and management', $ team ); Foreach ($ book as $ k => $ val) // meaning for $ book each $ value () If (is_array ($ val) foreach ($ val as $ value) echo $ value .' '; Else echo $ k. '=>'. $ val .' '; ?> |
Example 2
| The code is as follows: |
|
$ Array = array ('saipan (symbian) '=> array (1 => 's60v3 horizontal version', 2 => 's60v3', 3 => 's60v5 '), 'Android (android) '=> array (4 => 'android2. 1 and later versions ', 6 => 'Android 1.5', 7 => 'Android 1.6 ', 8 => 'Android 2.1', 9 => 'Android 2.2 ', 10 => 'Android 2.3 ', 11 => 'Android 3.0', 12 => 'Android 3.1 ', 12 => 'Android 3.2', 12 => 'Android 4.0 ', 12 => 'Android 4.1 ', 12 => 'Android 4.2 '), 'Wp7 (Windowsphone) '=> array (5 => 'Windows Phone 7 system ') ); Foreach ($ array as $ c => $ cc) { Echo''. $ C .''; Foreach ($ cc as $ v => $ vv) { If ($ addRow ["sjos"] = $ v) {$ select = "selected";} else {$ select = "";} Echo''. $ Vv .''; } } ?> |
