我们有<代码>$和$
变量,这些变量每次改动。
每一条<代码> 我们应当创建新的变式<代码>_$temp_title_%id%,并给它$
s Value。
和:
$id = 10;
$title = Hello people! ;
$temp_title_10 = Hello people! ;
从事这项工作:
$temp_title_ . $id = $title;
感谢。

如何使用阵列? 一个阵列是保存多种价值观的更好办法。 很多,、
$title_array = array();
$id = 10;
$title = Hello people! ;
$title_array[$id] = $title;
如果您的<代码>$id变量永远是惯用的,那么如果你重新尝试坚持您的变量的话,将其放在一个阵列中可能更好。
$persistence_array = array();
while (some_requirement) {
$id = ...;
$title = ...;
$persistence_array[$id] = $title;
}
如果$id
可能也含有甲型数字数据,那么你总是能够以同样的方式使用斜体/字典(用少量额外逻辑,你甚至可以为同一数字储存多种数值)。
<>DON T DO THIS: 如果你真的<>? 届时,您可使用variable factors。 但请不要。
使用:
$metavariable = "temp_title_".$id;
$$metavariable = $title; // note the $$
${ temp_title_ . $id} = $title;
echo $temp_title_10;
我认为,你努力做些什么是坏的想法,但这里却想如何做:
$GLOBALS["temp_title_".$id]=$title;
或者,你可以这样做:
$varname="temp_title_".$id;
$$varname=$title;
我认为,你再次努力做到的最正确办法是使用一个阵列:
// Somewhere in the PHP script:
$an_array=array();
// To assign:
$an_array[$id]=$title;
// To retrieve:
echo $an_array[$id];
Use variable variable of PHP http://php.net/manual/en/language.variables.variable.php
$variable = $title. _ .$id
$$variable = hello, world!
