在循环中更改变量名称

问题描述：

I have more than 50 string. I need to put those string into one array. I try to use loop to create it. however I have trouble on auto increment var's name. $string.$s($string1, $string2). It will become Undefined variable, Any way to change var's name?

$string0="ABC";
$string1="DEF";
$string2="GHI";
...


$data=array($string0, $string1, $string2...);

for($s=0; $s<50; $s++){
    $data[$s]=$string.$s;
}

我有超过50个字符串。我需要将这些字符串放入一个数组中。我尝试使用循环来创建它。但是我在自动增量var的名字上遇到了麻烦。 $ string。$ s code>（ $ string1，$ string2 code>）。它将成为Undefined变量，是否可以更改var的名称？ p>

  $ string0 =“ABC”; 
 $ string1 =“DEF”; 
 $ string2 =“GHI  “; 
 ... 
 
 
 $ data = array（$ string0，$ string1，$ string2 ...）; 
 
for（$ s = 0; $ s＆lt; 50; $ s ++）{  
 $ data [$ s] = $ string。$ s; 
} 
  code>  pre> 
  div>

答

Not

$string.$s;

But

${'string'.$s};

Needless to say, the best solution is:

$data = array(
    'ABC',
    'DEF',
    'GHI',
);

$data = array();
$data[] = 'ABC';
$data[] = 'DEF';
$data[] = 'GHI';

$data = array();
$data[0] = 'ABC';
$data[1] = 'DEF';
$data[2] = 'GHI';

You can also replace them by your editor's function.

I'll take one example, Notepad++. (Japanese plug-in is set on, sorry)

Let's try like this:

Points:

Search by (\$string)([0-9]+)(=)
Replace to \1[\2]\3
Mode Regex

答

something like this should work I guess :

for($s=0; $s<50; $s++)
{
    $myvar = "string" . $s;
    $data[$s]=$$myvar;
}
