str_replace 数组替换应用例子

str_replace 数组
//条件是替换与被替换数组长度必须相等
$t =array('<','>');
$e =array('<','>');

print_r ( str_replace($t,'ddd',$t));
/*
(
    [0] => ddd
    [1] => ddd
)
*/

print_r( str_replace($t,$e,$t) );

/*
Array
(
    [0] => <
    [1] => >
)
*/

//再测试字符串与数组
$t =array('<','>');
$e =array('<','>');
$str = " print_r ( str_replace($t,'str_replace',$str));
