PHP 字符串转数组

note.php

<?php

  //explode用法：

  $var = '10, 24, 29, 32, 56';

  $ary = explode(",", $var);
  
  print_r ( $ary ); // Array ( [0] => 10 [1] => 24 [2] => 29 [3] => 32 [4] => 56 )
  
  //str_split用法：一般用于固定字符数分隔
  
  $strs = 'abcdefg';
  
  $arys = str_split($strs, 2);
  
  print_r ( $arys ); // Array ( [0] => ab [1] => cd [2] => ef [3] => g )
