[英]Generating a JavaScript array from a PHP array
Suppose that I have a string $var
: 假设我有一个字符串$var
:
//php code
$var = "hello,world,test";
$exp = explode(",",$var);
Now I get the array as exp[0],exp[1],exp[1]
as 'hello'
, 'world'
and 'test'
, respectively. 现在我将数组分别作为exp[0],exp[1],exp[1]
作为'hello'
, 'world'
和'test'
。
I want to use this all value in javascript in this: 我想在javascript中使用这个全部值:
var name = ['hello','world','test'];
How can I generate that JavaScript in PHP? 如何在PHP中生成JavaScript?
I would have thought json_encode
would be the most reliable and simplest way. 我原以为json_encode
是最可靠和最简单的方法。
Eg 例如
$var = "hello,world,test";
$exp = explode(",",$var);
print json_encode($exp);
Wouldn't an easier way be like this: 不是一个更容易的方式是这样的:
$var = "hello,world,test";
$var = str_replace(",", "','", $var);
Then wherever you're spitting out JavaScript (assuming you can use PHP there): 然后,无论你在哪里吐出JavaScript(假设你可以在那里使用PHP):
var name = ['<?php echo $var; ?>'];
This doesn't deal properly with quoted values though - if you want that, you're better off with using fgetscsv
et al. 但这并没有适当地处理引用的值 - 如果你想要,你最好使用fgetscsv
等。
If you're determined to use explode
, then you can use its other-half, implode
like this in your output: 如果你决定使用explode
,那么你可以在输出中使用它的另一半,内implode
这样的内容:
var name = ['<? php echo implode("','", $var); ?>'];
