Describes how to split strings in PHP. Result: Array ([0] 1 [1] 2 [2] 3 [3] 4) defines and uses the str_split () function to split the string into arrays. The length syntax indicates the number of each string.Result: Array ([0] => 1 [1] => 2 [2] => 3 [3] => 4)

Definition and usage
The str_split () function separates strings into arrays.

Length indicates the number of strings.

Str_split (string, length) the default length is 1. if it is str_split ($ str, 2), the result is Array ([0] => 12 [1] => 34)

If it is $ str = '1 2 3 4 ', use the explode () function explode ('', $ str) to separate it by space.

If the content of an article is intercepted by the number of characters: Use the strlen () function and substr () string truncation function to split the string in PHP. for example:

 
 

  
  
<? Php $ len = strlen ($ row ['Game _ detail']);
  
  
// Obtain the length of the string;
  
  
If ($ len> 102)
  
  
// Judge whether a string is greater than 102 and outputs 102 strings.
  
  
{Echo $ s = substr ($ row ['Game _ detail'],
0,102); echo '...';
  
  
}
  
  
Else {echo $ row ["game_detail"];
  
  
// Otherwise, all are output;
  
  
}
  
  
?>
