数组分割 array_chunk(); 比较数组 1. array_diff() array_diff_assoc() 2. array_filter(); functionodd($var){ return($var%2==1); } functioneven($var){ return($var%2==0); } $arrayarray1=array("a"=>1,"b"=>2,"c"=>3,"d"=>4,"e"=>5); $arrayarray2=array(6,7,8,9,10,11,12); echo"Odd: "; print_r(array_filter($array1,"odd")); echo"Even: "; print_r(array_filter($array2,"even")); ?> 3. array_map(); $a=array(1,2,3,4,5); $b=array("uno","dos","tres","cuatro","cinco"); $c=array_map("show_Spanish",$a,$b); 4.str_split();
