In PHP, use foreach () to traverse a simple example of a two-dimensional array. PHP uses foreach () to traverse a simple example of a two-dimensional array.

Type 1

I want to use foreach () to traverse the entire two-dimensional array:

$ Team = array ('LK ',' OK '); $ book = array ('Linux server configuration and management', $ team ); foreach ($ book as $ k => $ val) // for $ book each $ value (as) echo $ k. '=> '. $ val. '';

The output result is:

0 => linux server configuration and management
1 => Array

Of course, I actually want all the specific content, not the output array...

Therefore, add a judgment statement as follows:

$ Team = array ('LK ',' OK '); $ book = array ('Linux server configuration and management', $ team ); foreach ($ book as $ k => $ val) // meaning for $ book each $ value (as) if (is_array ($ val )) foreach ($ val as $ value) echo $ value. ''; else echo $ k. '=> '. $ val. '';

The output is:

0 => linux server configuration and management
Lk
OK
