Try explode:

试着爆炸:

$myString = "9,admin@example.com,8";
$myArray = explode(',', $myString);
print_r($myArray);

Output :

输出:

Array
(
    [0] => 9
    [1] => admin@example.com
    [2] => 8
)

#2

$myString = "9,admin@example.com,8";
$myArray = explode(',', $myString);
foreach($myArray as $my_Array){
    echo $my_Array.'<br>';  
}

Output

输出

9
admin@example.com
8

#3

$string = '9,admin@google.com,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，我将使用fgetcsv()(或者如果有PHP V5.3，则使用str_getcsv()))。这将允许您正确地解析引用的值。如果不是csv，那就应该使用explosion()。

Code:

代码:

$string = "9,admin@example.com,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);

简单地说，您可以使用explosion ($delimiter， $string);

But in a broad way, with Manual Programming :

但从广义上讲，通过手工编程:

        $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);

Outpou:print_r(resultArr美元);

Array
(
    [0] => ab
    [1] => cdefg
    [2] => xyx
    [3] => ht623
)
