How to use PHP associative arrays _php Tutorial

When we operate the database, we need to use theLet's look at an array traversal of a basic number format:

 
  
  

  
   
   
 Php 
  
   
   
$temp [0] = "Richmond"; 
  
   
   
$temp [1] = "tigers"; 
  
   
   
$temp [2] = "premiers"; 
  
   
   

  
   
   
For ($x=0; $x<Count  ($temp); $x + + )
  
   
   
{ 
  
   
   
echo $temp [$x]; 
  
   
   
echo ""; 
  
   
   
} 
  
   
   
?> 
 
  
  

Another way to save more code, however, is:

 
  
  

  
   
   
 Php 
  
   
   
$ Temp  Array("Richmond", "tigers", "premiers"); 
  
   
   
foreach ($temp as $element) 
  
   
   
echo "$element"; 
  
   
   
?> 
 
  
  

foreach can also output text subscript:

 
 

  
  
 
   
   !--? php       
 
   
  $  temp   =  array   ("club" =   ;    " Richmond ",  
 
   
 " nickname "=   ;    "Tigers",  
 
   
  "aim" =   ;    "premiers");  
 
   
   
 
   
  foreach ($temp as $  key   =   ;    $value)  
 
   
  echo "$key: $value";  
 
   
     "    
 
  
 
 

This is the relevant use of the PHP associative array in the database.
