一维数组取一部分
array_slice() 函数在数组中根据条件取出一段值，并返回。
1 <!DOCTYPE html> 2 <html> 3 <body> 4 5 <?php 6 $a=array("a"=>"red","b"=>"green","c"=>"blue","d"=>"yellow","e"=>"brown"); 7 print_r(array_slice($a,1,2)); 8 9 $a=array("0"=>"red","1"=>"green","2"=>"blue","3"=>"yellow","4"=>"brown"); 10 print_r(array_slice($a,1,2)); 11 ?> 12 13 </body> 14 </html>
结果
1 Array ( [b] => green [c] => blue ) 2 Array ( [0] => green [1] => blue )
