What is the number of fields in a query array?

$r =mysql_query (' Select Orderid,zhuangtai,group_concat (' name ') as Name,group_concat (' Shouji ') as Shouji,group_concat (' sex ') as sex from ' Order ' GROUP by OrderID '); echo "
 
  
  
   
   
  "; echo "
  
   
   while ($row =mysql_fetch_assoc ($r)) { $shouji _arr=explode (', ', $row [' Shouji ']); $sex _arr=explode (', ', $row [' sex ']); echo " 
    "; foreach (Explode (', ', $row [' name ']) as $k = + $v) { echo] 
    
      "; echo " 
     "; echo " 
    "; }} echo " 
   
 
    
 
     
name
 
     
Mobile phone
 
     
Sex
 
    
 
     
Order number: ". $row [OrderID]." Status: ". $row [' Zhuangtai ']."
 
    
$v
 
     
$shouji _arr[$k]
 
     
$sex _arr[$k]
 
  
  
";

This is an iteration of the loop output, and I want to know how to get

$v $shouji_arr[$k] $sex _arr[$k]

, what is the number of $v? That means, how to get the actual output to show after thisHow many lines are there? Because I need to add a merged cell, similar to theMerged cellsBecause I don't know this groupHow many lines, that is, the number of $v, so do not know rowspan This value is how much!


Do not know my statement, we do not hear clearly, is this foreach output display, but can not determine how many lines of output, need to get the number of $v, because a $v to occupy a row!

Reply to discussion (solution)

foreach ($t =explode (', ', $row [' name ']) as $k = = $v) {
Count ($t) is the number of $v

You can also add a count (*) to the SQL string to get

You can also define an shaping variable outside the Foreach loop to be 0

Self-increment in the loop body

For example
$i = 0;
foreach ()
{
$i + +;
}

Thank you very much for the moderator's answer, and @zhangbin1988 's answer, if I add a direct in the foreach

12121

, the merged cell will also loop through the count ($t) times, so how can I output this cell only once? If this cell is placed alone in the outside of the foreach, it is misplaced, ask the big guys!

$t = Explode (', ', $row [' name ']);
$s = "contents of merged cells";
foreach ($t as $k = = $v) {
echo "". $s;
echo "$v $shouji_arr[$k] $sex _arr[$k]";
echo "";
$s = "; Empty when the output is over.
}
