For example

$ Contents = curl_exec ($ ch );

Preg_match_all ("/(. *) <\/td>/", $ contents, $ arr );
For ($ I = 0; $ I <= 100; $ I ++)
{
 
Print_r ($ arr [1] [$ I]);
If ($ I + 1) % 1 = 0)
{Echo'
';}
}

Instead of printing $ arr, I put it in a string variable.
------ Solution --------------------

$ Txt = '';
For ($ I = 0; $ I <= 100; $ I ++ ){
$ Txt. = $ arr [1] [$ I]);
If ($ I + 1) % 1 = 0 ){
$ Txt. ='
';
}
}
