如何用一些值增加变量并对结果重新排序

Question

我想用这些值增加这个变量：

$Variable = "AAAA1 VALUE1; \
             BBBB1 VALUE1; \
             CCCC1 VALUE1";

所以我做了这个简单的代码：

for($i=1; $i<3; $i++) {
$Variable = "AAAA$i VALUE$i; \
             BBBB$i VALUE$i; \
             CCCC$i VALUE$i";
}

我得到了这 2 个输出结果：

AAAA1 VALUE1
BBBB1 VALUE1
CCCC1 VALUE1

AAAA2 VALUE2
BBBB2 VALUE2
CCCC2 VALUE2

但我想要的是获得这样的完整结果：

AAAA1 VALUE1
AAAA2 VALUE2

BBBB1 VALUE1
BBBB2 VALUE2

CCCC1 VALUE1
CCCC2 VALUE2

Answer 1

打击代码：

"AAAA$i VALUE$i;  
 BBBB$i VALUE$i;  
 CCCC$i VALUE$i";

您想在每一行中进行迭代！

$variable = explode("\n",$Variable);

现在 $variable 是可迭代的，或者使用数组：

$variable=[
             "AAAA%input1% VALUE%input1%;",
             "BBBB%input1% VALUE%input1%;",
             "CCCC%input1% VALUE%input1%;",
];

$final_string="";
foreach($variable as $var){

    for($i=1; $i<3; $i++) {
        $final_string. = str_replace("%input1%",$i,$var) ."\n";
    }

}

echo $final_string;

Answer 2

您可以将字符串设为数组并逐项循环，然后在类似于您的 for 循环中构建字符串。

$Variable = "AAAA VALUE
BBBB VALUE
CCCC VALUE";
$startval = 1;
$endval = 5;

$var = explode("\n", $Variable);

$str = "";
foreach($var as $v){
    $temp = explode(" " , $v);
    //Loop from startval to endval and build your string
    for($i=$startval; $i<=$endval; $i++){
        $str .= $temp[0] .$i . " " . $temp[1] .$i. "\n";
    }
    $str .= "\n"; // add new line
}

echo $str;

输出：

AAAA1 VALUE1
AAAA2 VALUE2
AAAA3 VALUE3
AAAA4 VALUE4
AAAA5 VALUE5

BBBB1 VALUE1
BBBB2 VALUE2
BBBB3 VALUE3
BBBB4 VALUE4
BBBB5 VALUE5

CCCC1 VALUE1
CCCC2 VALUE2
CCCC3 VALUE3
CCCC4 VALUE4
CCCC5 VALUE5
