Discussion on the specific way of PHP split string _php Tutorial

We are usingResult: Array ([0] = 1 [1] = 2 [2] = 3 [3] = 4)

Definition and usage
The Str_split () function splits a string into an array.

Syntax length indicates the number of each string

Str_split (string,length) The default length is 1 above if it is Str_split ($STR, 2) result for array ([0] = [1] = 34)

If it is $str= ' 1 2 3 4 ' This time use explode () function explode (", $str) separated by spaces

If the content of an article is truncated by the number of characters: Use the strlen () function and the substr () string intercept function to implement the PHP split string function, such as:

 
  
  
 
   
   
  <   ? PHP $  len   =  strlen   ( $row [' Game_detail ']);   
 
   
   
 //Gets the length of the string;  
 
   
   
  if ($len     102)  
 
   
   
 //judgment string if it is greater than 102, the output of 102 strings.  
 
   
   
  {echo $  s   =  substr   ($row [' Game_detail '], 
 0,102), echo ' ... ';  
 
   
   
 }  
 
   
   
  else{echo $row ["Game_detail"];  
 
   
   
 //otherwise output all;  
 
   
   
 }  
 
   
   
 ?>< /span>   
 
  
  
 

That is, make a judgment before the output. strlen (string name): substr (String, 0,102) the range to be divided by 0-103. These are all the methods of PHP split string, I hope you have some control.
