Question

我想拆分数组元素的字符串。我必须将它拆分为第五个字符，但如果它位于单词的中间，则将其拆分为最近的空格。像这样：

// I have array like these
$array={"How are you ?","I am fine."};

//I want output like if we take length = 5.

$array1 = {"How are","you ?","I am fine."};  // array1[0] =how a   should be    array1[0] = how are  .

Answer 1

查找距离第五个字符最近的空格。然后从0返回第一部分直到该字符并将其放入新数组。然后将第二个块（直到结束的那个）放入同一个数组中。

foreach ($array as $val) {
    $strpos = strpos($val, " ", 5);
    $array1[] = substr($val, 0, $strpos);
    $array1[] = substr($val, $strpos+1, strlen($val));
}

如何在PHP中从数组元素中拆分字符串？
