How to save array to file format in php? Example code

$file="./cache/file.cache";
$array = array("color" => array("blue", "red", "green"),
 "size" = > array("small", "medium", "large"));
//Cache
file_put_contents($file,serialize($array));//Write cache
//Read cache
$handle = fopen($file, "r");
$cacheArray = unserialize(fread($handle, filesize ($file)));

Second method:

Post a few functions first:

//Write
function cache_write($name, $var, $values) {
 $cachefile = S_ROOT.'./data/data_'.$name.'.php';
 $cachetext = " "if(!defined('CHECK_CODE')) exit('Access Denied');rn".
 '$'.$var.'='.arrayeval($values).
 " rn?>";
 if(!swritefile($cachefile, $cachetext)) {
 exit("File: $cachefile write error.");
 }
}
//Convert array into string
function arrayeval( $array, $level = 0) {
 $space = '';
 for($i = 0; $i <= $level; $i++) {
 $space .= "t";
 }
 $evaluate = "Arrayn$space(n";
 $comma = $space;
 foreach($array as $key => $val) {
 $key = is_string($key) ? '''.addcslashes($key, ''\').''' : $key;
 $val = !is_array($val) && (!preg_match("/^-?d+$/", $val) || strlen($val) > 12) ? '''.addcslashes($val, ''\').''' : $val;
 if(is_array($val)) {
 $evaluate .= "$comma$key => ". arrayeval($val, $level + 1);
 } else {
 $evaluate .= "$comma$key => $val";
 }
 $comma = ",n$space";
 }
 $evaluate .= "n$space)";
 return $evaluate;
}
//Write file
function swritefile($filename, $writetext, $openmod='w') {
 if(@$fp = fopen($ filename, $openmod)) {
 flock($fp, 2);
 fwrite($fp, $writetext);
 fclose($fp);
 return true;
 } else {
 runlog('error', "File : $filename write error.");
 return false;
 }
}

Call:

cache_write('file', 'arrayName', $array);

include format:

@include ('./data/data_cache.php'); //Array reordering sort($arrayName);
