print an array as code
提问by Ward Bekker
I want to convert a big yaml file to PHP array source code. I can read in the yaml code and get back a PHP array, but with var_dump($array) I get pseudo code as output. I would like to print the array as valid php code, so I can copy paste it in my project and ditch the yaml.
我想将一个大的 yaml 文件转换为 PHP 数组源代码。我可以读入 yaml 代码并取回一个 PHP 数组，但是使用 var_dump($array) 我得到伪代码作为输出。我想将数组打印为有效的 php 代码，因此我可以将其复制粘贴到我的项目中并丢弃 yaml。

You're looking for var_export.
您正在寻找var_export.

You could use var_export, serialize(with unserialize on the reserving end), or even json_encode(and use json_decode on the receiving end). The last one has the advantage of producing output that can be processed by anything that can handle JSON.
您可以使用var_export、serialize（在保留端反序列化），甚至json_encode（并在接收端使用 json_decode）。最后一个的优点是生成的输出可以被任何可以处理 JSON 的东西处理。

Don't know why but I could not find satisfying code anywhere.
不知道为什么，但我在任何地方都找不到令人满意的代码。
Quickly wrote this. Let me know if you find any errors.
赶紧写了这篇。如果您发现任何错误，请告诉我。
function printCode($array, $path=false, $top=true) {
$data = "";
$delimiter = "~~|~~";
$p = null;
if(is_array($array)){
foreach($array as $key => $a){
if(!is_array($a) || empty($a)){
if(is_array($a)){
$data .= $path."['{$key}'] = array();".$delimiter;
} else {
$data .= $path."['{$key}'] = \"".htmlentities(addslashes($a))."\";".$delimiter;
}
} else {
$data .= printCode($a, $path."['{$key}']", false);
}
}
}
if($top){
$return = "";
foreach(explode($delimiter, $data) as $value){
if(!empty($value)){
$return .= '$array'.$value."<br>";
}
};
return $return;
}
return $data;
}
//REQUEST
$x = array('key'=>'value', 'key2'=>array('key3'=>'value2', 'key4'=>'value3', 'key5'=>array()));
echo printCode($x);
//OUTPUT
$array['key'] = 'value';
$array['key2']['key3'] = 'value2';
$array['key2']['key4'] = 'value3';
$array['key2']['key5'] = array();
Hope this helps someone.

An other way to display array as code with indentation.
另一种将数组显示为带有缩进的代码的方法。
Tested only with an array who contain string, integer and array.
仅使用包含字符串、整数和数组的数组进行测试。
function bo_print_nice_array($array){
echo '$array=';
bo_print_nice_array_content($array, 1);
echo ';';
}
function bo_print_nice_array_content($array, $deep=1){
$indent = '';
$indent_close = '';
echo "[";
for($i=0; $i<$deep; $i++){
$indent.=' ';
}
for($i=1; $i<$deep; $i++){
$indent_close.=' ';
}
foreach($array as $key=>$value){
echo "<br>".$indent;
echo '"'.$key.'" => ';
if(is_string($value)){
echo '"'.$value.'"';
}elseif(is_array($value)){
bo_print_nice_array_content($value, ($deep+1));
}else{
echo $value;
}
echo ',';
}
echo '<br>'.$indent_close.']';
}
