perl VS php数据结构比较

------perl array----- ------php array------ @a=(); $a=array(); @a1=('aa',1,2); $a1=array('aa',1,2); @a2=0..9; $a2=range(0,9); $a[0]='sth'; $a[0]='sth'; $len=scalar
@a ; or $len=
@a ; $len=count($a); @a3=('bb',@a1,@a2); $a3=array_merge('xx',$a1,$a2); $a[@a]='new'; #push $a[]='new'; #push push array_push pop array_pop shift array_shift unshift array_unshift splice array_splice foreach (@a) {...} foreach ($a as $i) {...} ------perl hash------ ------php hash------ %h=(); $h=array(); %h=('x'=>'y','z'=>'w'); $h=array('x'=>'y','z'=>'w'); $h{'x'}=1; $h['x']=1; while (($key,$value)=each(%h)){...} foreach ($h as $key=>$value){...} @k=keys(%h); $k=array_keys($h); @v=values(%h); $v=array_values($h); delete $h{'x'}; unset($h['x']); ------perl数据结构------ ------php数据结构------ %h=('a'=>1,'b'=>2); $h=array('a'=>1,'b'=>2); @a=('one','two','three'); $a=array('one','two','three'); @mix=(%h,
