I just wrote this function to output an array as text:

Should output nicely formatted array.

IMPORTANT NOTE:

Beware of user input. 

This script was created for internal use. 

If you intend to use this for public use you will need to add some additional data validation to prevent script injection.

This is not fool proof and should be used with trusted data only.

The following function will output something like:

<pre><code>$var = array(
 'primarykey' =&gt; array(
 'test' =&gt; array(
 'var' =&gt; array(
 1 =&gt; 99,
 2 =&gt; 500,
 ),
 ),
 'abc' =&gt; 'd',
 ),
);
</code></pre>

here is the function (note: function is currently formatted for oop implementation.)

<pre><code> public function outArray($array, $lvl=0){
 $sub = $lvl+1;
 $return = "";
 if($lvl==null){
 $return = "\t\$var = array(\n"; 
 }
 foreach($array as $key =&gt; $mixed){
 $key = trim($key);
 if(!is_array($mixed)){
 $mixed = trim($mixed);
 }
 if(empty($key) &amp;&amp; empty($mixed)){continue;}
 if(!is_numeric($key) &amp;&amp; !empty($key)){
 if($key == "[]"){
 $key = null;
 } else {
 $key = "'".addslashes($key)."'";
 }
 }

 if($mixed === null){
 $mixed = 'null';
 } elseif($mixed === false){
 $mixed = 'false';
 } elseif($mixed === true){
 $mixed = 'true';
 } elseif($mixed === ""){
 $mixed = "''";
 } 

 //CONVERT STRINGS 'true', 'false' and 'null' TO true, false and null
 //uncomment if needed
 //elseif(!is_numeric($mixed) &amp;&amp; !is_array($mixed) &amp;&amp; !empty($mixed)){
 // if($mixed != 'false' &amp;&amp; $mixed != 'true' &amp;&amp; $mixed != 'null'){
 // $mixed = "'".addslashes($mixed)."'";
 // }
 //}


 if(is_array($mixed)){
 if($key !== null){
 $return .= "\t".str_repeat("\t", $sub)."$key =&gt; array(\n";
 $return .= $this-&gt;outArray($mixed, $sub);
 $return .= "\t".str_repeat("\t", $sub)."),\n";
 } else {
 $return .= "\t".str_repeat("\t", $sub)."array(\n";
 $return .= $this-&gt;outArray($mixed, $sub);
 $return .= "\t".str_repeat("\t", $sub)."),\n"; 
 }
 } else {
 if($key !== null){
 $return .= "\t".str_repeat("\t", $sub)."$key =&gt; $mixed,\n";
 } else {
 $return .= "\t".str_repeat("\t", $sub).$mixed.",\n";
 }
 }
 }
 if($lvl==null){
 $return .= "\t);\n";
 }
 return $return;
 }
</code></pre>

Alternately you can use this script I also wrote a while ago:

This one is nice to copy and paste parts of an array.

( Would be near impossible to do that with serialized output )

Not the cleanest function but it gets the job done.

This one will output as follows:

<pre><code>$array['key']['key2'] = 'value';
$array['key']['key3'] = 'value2';
$array['x'] = 7;
$array['y']['z'] = 'abc';
</code></pre>

Also take care for user input.
Here is the code.

<pre><code>public static function prArray($array, $path=false, $top=true) {
 $data = "";
 $delimiter = "~~|~~";
 $p = null;
 if(is_array($array)){
 foreach($array as $key =&gt; $a){
 if(!is_array($a) || empty($a)){
 if(is_array($a)){
 $data .= $path."['{$key}'] = array();".$delimiter;
 } else {
 $data .= $path."['{$key}'] = \"".htmlentities(addslashes($a))."\";".$delimiter;
 }
 } else {
 $data .= self::prArray($a, $path."['{$key}']", false);
 } 
 }
 }
 if($top){
 $return = "";
 foreach(explode($delimiter, $data) as $value){
 if(!empty($value)){
 $return .= '$array'.$value."&lt;br&gt;";
 }
 };
 echo $return;
 }
 return $data;
 }
</code></pre>

blocks|key|1064027|text|然而，op需要写入数组，因为它在文件中。我登陆这个页面是为了找到一个解决方案，在这里我可以将数组写入文件，然后再使用php轻松读取。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1064028|我已经通过使用json_encode自己找到了解决方案，所以其他任何人都在寻找相同的解决方案，下面是代码：|1064029|file_put_contents('array.tmp',+json_encode($array));|code-block|syntax|javascript|1064030|然后阅读|1064031|$array+=+file_get_contents('array.tmp');

However op needs to write array as it is on file I have landed this page to find out a solution where I can write a array to file and than can easily read later using php again.

I have found solution my self by using json_encode so anyone else is looking for the same here is the code:

<pre><code>file_put_contents('array.tmp', json_encode($array));
</code></pre>

than read

<pre><code>$array = file_get_contents('array.tmp');
$array = json_decode($array,true);
</code></pre>

I would like to print an array to a file.

I would like the file to look exactly similar like how a code like this looks.

<code>print_r ($abc);</code> assuming $abc is an array.

Is there any one lines solution for this rather than regular for each look.

P.S - I currently use serialize but i want to make the files readable as readability is quite hard with serialized arrays.

Print array to a file

我想要将数组打印到文件中。我希望文件看起来完全像这样的代码看起来。假设$abc是一个数组，则为print_r ($abc);。有没有一条线来解决这个问题，而不是每次看起来都有规律。P.S -我目前使用序列化，但我想让文件具有可读性，因为序列化数组的可读性相当困难。
