如何将PHP数组转换成这样的格式
Array
(
[0] => 001-1234567
[1] => 1234567
[2] => 12345678
[3] => 12345678
[4] => 12345678
[5] => AP1W3242
[6] => AP7X1234
[7] => AS1234
[8] => MH9Z2324
[9] => MX1234
[10] => TN1A3242
[11] => ZZ1234
)
到下面格式的Javascript数组?
var cities = [
"Aberdeen",
"Ada",
"Adamsville",
"Addyston",
"Adelphi",
"Adena",
"Adrian",
"Akron",
"Albany"
];

我使用了一个伪php数组
<?php
// instead to create your array like this
$php_array = ["The","quick","brown","fox","jumps","over","the","lazy","dog"];
// do it like this (a simple variable but with separator)
$php_fake_array = "The,quick,brown,fox,jumps,over,the,lazy,dog";
?>
<script type="text/javascript">
// use the same separator for the JS split() function
js_array = '<?php echo $php_fake_array; ?>'.split(',');
</script>
如果你的数组是未知的(已经创建)
<?php
$php_array = file('my_file.txt');
$php_fake_array = "";
// transform your array with concatenate like this
foreach ($php_array as $cell){
// since this array is unknown, use clever separator
$php_fake_array .= $cell.",,,,,";
}
?>
<script type="text/javascript">
// use the same separator for the JS split() function
js_array = '<?php echo $php_fake_array; ?>'.split(',,,,,');
</script>

我发现在Javascript中使用PHP数组的最快和最简单的方法是这样做:
PHP:
$php_arr = array('a','b','c','d');
Javascript:
//this gives me a JSON object
js_arr = '<?php echo JSON_encode($php_arr);?>';
//Depending on what I use it for I sometimes parse the json so I can work with a straight forward array:
js_arr = JSON.parse('<?php echo JSON_encode($php_arr);?>');
这么简单…!
使用这个方法:
<?php echo json_encode($your_array); ?>;
在laravel blade{{}}中使用以下方法:
{{ str_replace('"', '', json_encode($your_array)) }}
为关联和非关联数组工作。
对于Laravel用户:使用@json
var cities = @json($data);
官方文档中有解释:https://laravel.com/docs/8.x/blade#rendering-json:
这里有许多好的和复杂的解决方案，这是一种不需要在用户端解析json的方法。
$mtc=array();
$replace=array();
$x = json_encode($thearray);
preg_match_all('/"[a-z0-9_]*":/',$x,$mtc);
foreach($mtc[0] as $v){
array_push($replace,str_replace('"','',$v));
}
$x = str_replace($mtc[0],$replace,$x);
echo '<script type="text/javascript">x='.$x.';console.log(x);</script>';
这适用于具有多个级别的索引数组和关联数组(任何组合)，并且不需要用户端json解析。
对于Laravel, Blade{{}}语句通过PHP的htmlspecialchars函数自动发送，以防止XSS攻击。你的数据是不转义的，你可以使用以下语法:
const jsArray = {!! str_replace('"', '', json_encode($array)) !!};
