Try explode:
尝试爆炸：
$myString = "9,[email protected],8";
$myArray = explode(',', $myString);
print_r($myArray);
Output :
输出 ：
Array
(
[0] => 9
[1] => [email protected]
[2] => 8
)

$string = '9,[email protected],8';
$array = explode(',', $string);
For more complicated situations, you may need to use preg_split.
对于更复杂的情况，您可能需要使用preg_split.

If that string comes from a csv file, I would use fgetcsv()(or str_getcsv()if you have PHP V5.3). That will allow you to parse quoted values correctly. If it is not a csv, explode()should be the best choice.
如果该字符串来自 csv 文件，我会使用fgetcsv()（或者str_getcsv()如果您有 PHP V5.3）。这将允许您正确解析引用的值。如果不是csv，explode()应该是最好的选择。

Code:
代码：
$string = "9,[email protected],8";
$array = explode(",", $string);
print_r($array);
$no = 1;
foreach ($array as $line) {
echo $no . ". " . $line . PHP_EOL;
$no++;
};

In simple way you can go with explode($delimiter, $string);
以简单的方式，您可以使用explode($delimiter, $string);
But in a broad way, with Manual Programming :
但从广义上讲，使用手动编程：
$string = "ab,cdefg,xyx,ht623";
$resultArr = [];
$strLength = strlen($string);
$delimiter = ',';
$j = 0;
$tmp = '';
for ($i = 0; $i < $strLength; $i++) {
if($delimiter === $string[$i]) {
$j++;
$tmp = '';
continue;
}
$tmp .= $string[$i];
$resultArr[$j] = $tmp;
}
Outpou : print_r($resultArr);
输出： print_r($resultArr);
Array
(
[0] => ab
[1] => cdefg
[2] => xyx
[3] => ht623
)

The Best choice is to use the function "explode()".
最好的选择是使用函数“explode()”。
$content = "dad,fger,fgferf,fewf";
$delimiters =",";
$explodes = explode($delimiters, $content);
foreach($exploade as $explode) {
echo "This is a exploded String: ". $explode;
}
If you want a faster approach you can use a delimiter tool like Delimiters.coThere are many websites like this. But I prefer a simple PHP code.
如果你想要更快的方法，你可以使用像Delimiters.co这样的分隔符工具有很多这样的网站。但我更喜欢简单的 PHP 代码。

explodehas some very big problems in real life usage:
explode在实际使用中存在一些非常大的问题：
count(explode(',', null)); // 1 !!
explode(',', null); // [""] not an empty array, but an array with one empty string!
explode(',', ""); // [""]
explode(',', "1,"); // ["1",""] ending commas are also unsupported, kinda like IE8
this is why i prefer preg_split
这就是为什么我更喜欢preg_split
preg_split('@,@', $string, NULL, PREG_SPLIT_NO_EMPTY)
the entire boilerplate:
整个样板：
/** @brief wrapper for explode
* @param string|int|array $val string will explode. '' return []. int return string in array (1 returns ['1']). array return itself. for other types - see $as_is
* @param bool $as_is false (default): bool/null return []. true: bool/null return itself.
* @param string $delimiter default ','
* @return array|mixed
*/
public static function explode($val, $as_is = false, $delimiter = ',')
{
// using preg_split (instead of explode) because it is the best way to handle ending comma and avoid empty string converted to ['']
return (is_string($val) || is_int($val)) ?
preg_split('@' . preg_quote($delimiter, '@') . '@', $val, NULL, PREG_SPLIT_NO_EMPTY)
:
($as_is ? $val : (is_array($val) ? $val : []));
}
