如何用PHP检测和删除重复的内容，忽略重复出现的"'n"-s？

我有以下字符串：

''nrazor989''nalcatraz''nartez''ntajemnicyxd''nmrazor''nqwertyuiop''npomroczny4''nomgdmg''ngreat_jojek''nmaciekcz242''nkaka2610''nteleskop1''nspciokawa ''nlocek18''nacpi999''npavel1909''npozbierany''nkothuzan''nnistrim''nroch''nmario''nacatraz''n

请尝试

$str = 'your string';
$ar = explode(''n', $str);
$ar = array_unique($ar);
echo implode(''n', $ar); //edited - original code had $arr

使其成为唯一数组：

$massiveString = ''nrazor989'nalcatraz'nartez'ntajemniczyxd'nmrrazor'nqwertyuiop'npomroczny4'nomgdmg'ngreat_jojek'nmaciekcz242'nkaka2610'nteleskop1'nsupciokawa'nklocek18'nkacpi999'npawel1909'npozbierany'nkelthuzan'nistrim'ngroch'nmario'nalcatraz'n';
echo implode(''n', array_unique(explode(''n', $massiveString)));
