PHP stores the array as a text file method summary,

PHP cache array of variables, in effect, is to write the array of PHP to a text file or a suffix called. php is stored, directly call this file when used. So how do you use PHP to save an array as a text-formatted file? Three ways to write a PHP array to a file to cache an array are shared below.
(1) Use Serialize to store array serialization as a text file, and then use Unserialize restore when calling

<?php $file = './cache/phone.php '; $array =array (' color ' = = Array (' Blue ', ' red ', ' green '), ' size ' = = Array (' small ', ' medium ', ' large ')); Cache if (False!==fopen ($file, ' w+ ')) {   

(2) The self-created array is saved as a standard array format, although it is more complex to save, but simple to call

<?php $file = './cache/phone.php '; $array =array (' color ' = = Array (' Blue ', ' red ', ' green '), ' size ' = = Array (' small ', ' medium ', ' large '));  Cache_write ($file, $array, ' rows ', false);   Write function Cache_write ($filename, $values, $var = ' rows ', $format =false) {$cachefile = $filename; $cachetext = "<?php\r\n". '   $ '. $var. ' = '. Arrayeval ($values, $format). ";"; Return WriteFile ($cachefile, $cachetext);   }//array converted into string function arrayeval ($array, $format =false, $level =0) {$space = $line = ';     if (! $format) {for ($i =0; $i <= $level; $i + +) {$space. = "\ T";   } $line = "\ n"; } $evaluate = ' Array '. $line. $space. '   ('. $line;   $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, $format, $level + 1); }else{$evaluate. = $comma. $key. ' => '.     $val;   } $comma = ', '. $line. $space;   } $evaluate. = $line. $space. ') '; return $evaluate; }//write file function WriteFile ($filename, $writetext, $openmod = ' W ') {if (false!== $fp =fopen ($filename, $openmod)) {Flock ($f     p,2);     Fwrite ($fp, $writetext);     Fclose ($FP);   return true;   }else{return false;  } }

(3) using Var_export to store arrays directly into a text file as an array

<?php $file = './cache/phone.php '; $array =array (' color ' = = Array (' Blue ', ' red ', ' green '), ' size ' = = Array (' small ', ' medium ', ' large ')); The Cache $text = ' <?php $rows = '. Var_export ($array, true). '; '; if (False!==fopen ($file, ' w+ ')) {   file_put_contents ($file, $text);} else{   

The above is for you to introduce the three kinds of PHP to save the array as text format method, I hope that everyone's learning is helpful.
