When the page is running, there should be several pieces of information running, and the var_dump () function is used for output, there will be several results, but when the light is running, how can there be only one! Urgent. thank you.

Try this way

do{
$html_info="
 
 

  
  " ;
  
  
//var_dump($show_info["telephone"]) ;
  
  
$name=fun($show_info["username"]) ;
  
  
$html_info .="
  
  
".$name."***  ".substr($show_info["telephone"] ,0 ,7)."****
" ;
  
  
}while($show_info=mysql_fetch_array($show_mysql)) ;
  
  
$html_info .="
 
 
" ;
