如何随机播放阵列

Question

I am using this table to generate password. I am using this code to shuffle and it shuffles only rows and not columns randomly. I want to place them randomly in tables mixing both rows and column values.

$matrix=array();
$matrix[3][0]="h5";$matrix[3][1]="h3";$matrix[3][2]="96";$matrix[3][3]="45";$matrix[3][4]="oo";
$matrix[1][0]="39";$matrix[1][1]="k4";$matrix[1][2]="i2";$matrix[1][3]="j9";$matrix[1][4]="g5";
$matrix[0][0]="t1";$matrix[0][1]="2j";$matrix[0][2]="r3";$matrix[0][3]="f8";$matrix[0][4]="y9";
$matrix[4][0]="i3";$matrix[4][1]="k7";$matrix[4][2]="a1";$matrix[4][3]="e3";$matrix[4][4]="f6";
$matrix[2][0]="t9";$matrix[2][1]="e2";$matrix[2][2]="w3";$matrix[2][3]="r2";$matrix[2][4]="w3";
shuffle($matrix);
//Shuffle the array
foreach($matrix as $key => $value) {
echo "$value
}

Can anyone help me solve this.

$shuffled_ = array();
$shuffled = array();

foreach( $matrix as $val )
    foreach($val as $v)
        $shuffled_[] = $v;

shuffle($shuffled_);

foreach( $shuffled_ as $key => $val )
    $shuffled[ floor($key / 5) ][$key % 5] = $val;
