I created a two-dimensional array
class MyArray
{
public $arr=array();
public function create()
{
for($i=0;$i<=4;$i++)
{
for($j=0;$j<=4;$j++)
{
$this->arr[$i][$j]=0;
}
}
}
public function print()
{
for($i=0;$i<5;$i++)
{
for($j=0;$j<5;$j++)
{
echo $this->arr[$i][$j] . " ";
}
}
}
}
$arr1= new MyArray();
$arr1->create();
$arr1->print();
but when I display it looks like this:
0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0
What to do to look like this:
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0
0 0 0 0 0
Just add a <br />
tag after the inner for
loop, like this:
public function print(){
for($i=0;$i<5;$i++){
for($j=0;$j<5;$j++){
echo $this->arr[$i][$j] . " ";
}
echo "<br />";
}
}
由于我不知道您是否正在制作网页,因此您将需要echo
/ print
换行符\\n
或HTML换行符( <br>
或<br />
)作为MyArray::print
外循环的第二条语句MyArray::print
,具体取决于上下文(HTML5或HTML 4.01 / XHTML 1.0)。
This is print in single line because you are not using line break.
You need to add <br>
in another for loop as following:
public function print(){
for($i=0;$i<5;$i++){
for($j=0;$j<5;$j++){
echo $this->arr[$i][$j] . " ";
}
echo "<br />";
}
}
