使用PHP explode()函数

Question

我有一个问题,我想使用explode函数拆分一个字符串变量,但有一个限制,想象下一个字符串变量具有下一个值:

$data = "3, 18, 'My name is john, i like to play piano'";

使用explode函数:explode(",",$ data),输出将是:

array(
       [0] => 3,
       [1] => 18,
       [2] => 'My name is john,
       [3] => i like to play piano'
      );

我的目标是用逗号分隔变量$ data,排除''chatacters之间的变量.

例如 array( [0] => 3, [1] => 18, [2] => 'My name is john, i like to play piano' );

如果有人能告诉我这样做的方法,我将不胜感激.

Answer 1

这看起来很像CSV数据.您可以使用str_getcsv来解析它.

var_dump(str_getcsv("3, 18, 'My name is john, i like to play piano'", ',', "'"));

应该导致:

array(3) {
  [0] =>
  string(1) "3"
  [1] =>
  string(3) " 18"
  [2] =>
  string(12) "My name is john, i like to play piano"
}

您可能也希望trim通过使用array_map以下方法应用于每个数组元素:

$string = "3, 18, 'My name is john, i like to play piano'";
var_dump(array_map('trim', str_getcsv($string, ',', "'")));

Answer 2

使用:str_getcsv

// set the delimiter with ',', and set enclosure with single quote
$arr = str_getcsv ($data, ',', "'");

Answer 3

您可以使用str_getcsv()函数:

$data = "3, 18, 'My name is john, i like to play piano'";
$pieces = str_getcsv($data, ',', "'");

函数的第一个参数是要拆分的字符串.

第二个参数是您需要拆分的分隔符.

第三个参数是单个字符,当在第一个参数中用作一对(uninsecaped)时,将被视为一个字段,实际上忽略了该字符串之间的分隔符.
