Question

我想把我的字符串（用逗号分隔）放在两个不同的数组中。

$str = 1,First,2,Second,3,Third,4,Forth,5,Fifth

我的目标是对数字和文字进行分组。

$number = {1,2,3,4,5)
$text = {first, second, third, forth, fifth}

我尝试使用explode()，但我只能创建一个数组。

Answer 1

<?php

$str = array(1,'First',2,'Second',3,'Third',4,'Forth',5,'Fifth');

$letters =array();
$no = array();

for($i=0;$i<count($str);$i++){
  if($i%2 ==0){
    $letters[] = $str[$i];

  }else{
    $no[] = $str[$i];
  }
}
  print_r($no);
  print_r($letters);
?>

Answer 2

可能这可以帮到你

$str = '1,First,2,Second,3,Third,4,Forth,5,Fifth';

$array = explode(',',$str);

$number = array();
$string = array();


foreach($array as $val)
{
    if(is_numeric($val))
    {
        $number[] = $val;
    }
    elseif(!is_numeric($val))
    {
        $string[] = $val;
    }
}

echo $commNum = implode(',',$number); // These are strings
echo '<br/>'.$commStr = implode(',',$string); // These are strings

echo '<pre>';
print_r($number);  // These are arrays

echo '<pre>';
print_r($string);  // These are arrays

Answer 3

您可以使用explode，但在这种情况下需要应用一些过滤器is_numeric：

<?php

$str = '1,First,2,Second,3,Third,4,Forth,5,Fifth, erewwrw , 6 ';

$array = explode(',', $str);

$array_numbers = array();
$array_letters = array();

for($i = 0; $i < count($array); $i++) {
    if(is_numeric(trim($array[$i]))) {
      $array_numbers[] = trim($array[$i]);  
    } else {
      $array_letters[] = trim($array[$i]);
    }       
}
print_r($array_numbers);
print_r($array_letters);

?>

输出：

Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [4] => 5
)
Array
(
    [0] => First
    [1] => Second
    [2] => Third
    [3] => Forth
    [4] => Fifth
)

Answer 4

假设您的字符串包含数字后跟字符串，依此类推，

以下应该是解决方案。

创建两个空白数组：$numbers和$strings。

只需遍历数组并获得偶数和奇数元素。

偶数元素应该转到数字数组，奇数元素应该转到字符串数组。

$str = '1,First,2,Second,3,Third,4,Forth,5,Fifth';
$numbers = array();
$strings = array();
$temp = explode(',', $str);
$i=0;
foreach ($temp as $e) {
    if ($i%2) {
        $strings[] = $e;
    }
    else {
        $numbers[] = $e;
    }
    ++$i;
}

echo '<pre>';
print_r($numbers);
echo '</pre>';

echo '<pre>';
print_r($strings);
echo '</pre>';

如何将逗号分隔的字符串放在两个不同的数组中？
