Allocation data type of the smarty template engine

Allocation data type of the smarty template engine

This article mainly introduces the distribution data type of the smarty template engine. The instance analyzes the usage skills of the smarty template engine data type and has some reference value. For more information, see

 

 

This document describes how to use the smarty template engine to allocate data types. Share it with you for your reference. The specific analysis is as follows:

1. Allocate basic data

?

1 2 3 4 5 6 7 8 9 10 11

// Allocate basic data $ Smarty-> assign ("str", "hello smarty! "); $ Smarty-> assign ("int", 143 ); $ Smarty-> assign ("double", 12.1344 ); $ Smarty-> assign ("bool", true ); $ Smarty-> assign ("bool2", false ); String type: <{$ str }>< br/> Integer: <{$ int}> <br/> Floating Point: <{$ double}> <br/> Boolean Type: <{$ bool}> <br/> Boolean Type false: <{$ bool2}> <br/>

Browser display result:

1 indicates true, 0 indicates false, null indicates false, and nothing is displayed.

2. Allocating arrays of composite data

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23

// Index the Array $ Res = array ('shanghai', 'beijing', 'shenzhen '); $ Smarty-> assign ("arr", $ res ); // Associate an array $ Res2 = array ('city1 '=> 'beijing', 'city2' => 'guangzhou ', 'city3' => 'hunan '); $ Smarty-> assign ("arr2", $ res2 ); // Index two-dimensional array $ Res3 = array ( Array ('xiao Xiao ', 'changshan', 'wu bei'), array ('shanshan', 'changming ') ); $ Smarty-> assign ("arr3", $ res3 ); // Associate a two-dimensional array $ Res4 = array ( Array ('id' => '001', 'name' => 'zhang san', 'email '=> 'zhangsan @ zhang3.com '), Array ('url' => 'HTTP: // www.baidu.com ', 'age' => '28 ') ); $ Smarty-> assign ("arr4", $ res4 ); // Associate two-dimensional array 2 $ Res5 = array ( 'Emp1' => array ('id' => '001', 'name' => 'zhangsan', 'email '=> 'zhangsan @ zhang3.com '), 'Emp2' => array ('url' => 'HTTP: // www.baidu.com ', 'age' => '28 ') ); $ Smarty-> assign ("arr5", $ res5 );
