Teach you how to add a variable to a PHP string _php tutorial

We're on theHowever, it is necessary to add a variable description to the PHP string, although there is no error in the following example:

 
  
  

  
   
   
 Php 
  
   
   
$ Temp  Array("one" =>  1, "one" =>  2); 
  
   
   
Output:: The first element is 1 
  
   
   
echo "The first element is $temp [one]."; 
  
   
   
?> 
 
  
  

However, if there is no double quotation mark in the back of the Echo statement, it is necessary to give an error, so we recommend using curly braces:

 
  
  

  
   
   
 Php 
  
   
   
$ Temp  Array("one" =>  1, "one" =>  2); 
  
   
   
echo "The first element is {$temp [" one "]}."; 
  
   
   
?> 
 
  
  

These are the specific workarounds for adding variables to the PHP string.
