Questions about merging and displaying the same data-php Tutorial

To merge and display the same data, I use the SQL output data format as follows: leaders | Zhang San leaders | Li Si leaders | Wang Wu & nbsp; to display the data in a table: leaders | Zhang San & nbsp; | Li Si & nbsp; | how can I implement this? ------ solution ------------------ PHPcode $ aarray (array (lead, Zhang San), array (lead, merge and display the same data)
The data format output through SQL is as follows:
Lead | Zhang San
Lead | Li Si
Lead | Wang Wu
The expected table format is as follows:
Lead | Zhang San
| Li Si
| Wang Wu
How can this problem be achieved?

$ A = array ('authorization', 'Zhang San'), array ('authorization', 'Li si'), array ('authorization', 'Wang Wu ')); foreach ($ a as $ k => $ B) {if (! $ Tem [$ B [0]) $ tem [$ B [0] = $ B; else $ a [$ k] [0] = '';} echo"
  
  
   
   
"; Foreach ($ a as $ v) {echo"
   
   
      "; Echo" 
     "; Echo" 
     "; Echo" 
    ";} Echo"
