結合了兩種字符串用PHP

Question

我有兩個刺

a, b, d, e 

和

1, 52, 34, 56 

我想結合兩個字符串作爲

a/1, b/52, d/34, e/56 

我寫的一樣，我的代碼： -

$result2 = mysql_query($query2); 
    while($row2=mysql_fetch_array($result2)){ 
    $arr2 = explode(",",$row2['string1']); 
    $arr1 = explode(",",$row2['string2']); 
    for($i2 = 0; $i2 < count($arr1); $i2++) { 
     $raw_str = "".$arr2[$i2]."/".$arr1[$i2].","; 
     $query3 = "UPDATE table SET com_str='".$raw_str."' WHERE id='".$row2['id']."'"; 
     if (!mysql_query($query3)) 
     { 
      die('Error: ' . mysql_error()); 
     } 
    } 
    } 

我的代碼纔可以最後的值存儲只進databese： -

e/56, 

但我要完整的字符串存儲到數據庫中。

感謝提前

Answer 1

試試這個代碼：

$result2 = mysql_query($query2); 
while($row2=mysql_fetch_array($result2)){ 
    $arr2 = explode(",",$row2['string1']); 
    $arr1 = explode(",",$row2['string2']); 
    $raw_str = array(); 
    for($i2 = 0; $i2 < count($arr1); $i2++) 
     $raw_str[] = $arr2[$i2].'/'.$arr1[$i2]; 
    $query3 = "UPDATE table SET com_str='".implode(',',$raw_str)."' WHERE id='".$row2['id']."'"; 
    if (!mysql_query($query3)){ 
     die('Error: ' . mysql_error()); 
    } 

} 

你也應該看看naming your variables。

Answer 2

$letters = 'a, b, d, e'; 
$numbers = '1, 52, 34, 56'; 

preg_match_all('/\w+/', $letters, $letters); 
preg_match_all('/\d+/', $numbers, $numbers); 

$final = array(); 
foreach ($letters[0] AS $key => $letter) 
    $final[] = $letter . '/' . $numbers[0][$key]; 

echo join(', ', $final); 
// a/1, b/52, d/34, e/56

試試這個：

$result2 = mysql_query($query2); 
    while($row2=mysql_fetch_array($result2)){ 
    $arr2 = explode(",",$row2['string1']); 
    $arr1 = explode(",",$row2['string2']); 
    $raw_str = ""; 
    for($i2 = 0; $i2 < count($arr1); $i2++) { 
     $raw_str .= "".$arr2[$i2]."/".$arr1[$i2].","; 
    } 
    $query3 = "UPDATE table SET com_str='".$raw_str."' WHERE id='".$row2['id']."'"; 
    if (!mysql_query($query3)) 
    { 
     die('Error: ' . mysql_error()); 
    } 

    } 

Answer 4

$str1 = explode(',', 'a, b, d, e'); 
$str2 = explode(',', '1, 52, 34, 56'); 

if (count($str1) == count($str2)) 
{ 
    $result = array(); 

    foreach ($str1 as $key => $value) 
    { 
     $result[] = trim($value) . '/' . trim($str2[$key]); 
    } 

    $result = implode(', ', $result); 
} 

var_dump($result);
