本文讲述了php格式化json函数的示例代码。分享给大家供大家参考,具体如下:
<?php $arr = array("ret"=>0,"data"=>array('a' => 1, 'b' => '2', 'c' => 3, 'd' => 4, 'e' => 5)); $json = json_encode($arr); /** * Formats a JSON string for pretty printing * * @param string $json The JSON to make pretty * @param bool $html Insert nonbreaking spaces and <br />s for tabs and linebreaks * @return string The prettified output */ function _format_json($json, $html = false) { $tabcount = 0; $result = ''; $inquote = false; $ignorenext = false; if ($html) { $tab = " "; $newline = "<br/>"; } else { $tab = "t"; $newline = "n"; } for($i = 0; $i < strlen($json); $i++) { $char = $json[$i]; if ($ignorenext) { $result .= $char; $ignorenext = false; } else { switch($char) { case '{': $tabcount++; $result .= $char . $newline . str_repeat($tab, $tabcount); break; case '}': $tabcount--; $result = trim($result) . $newline . str_repeat($tab, $tabcount) . $char; break; case ',': $result .= $char . $newline . str_repeat($tab, $tabcount); break; case '"': $inquote = !$inquote; $result .= $char; break; case '\': if ($inquote) $ignorenext = true; $result .= $char; break; default: $result .= $char; } } } return $result; } echo _format_json($json); /* { "ret": 0, "data": { "a": 1, "b": 2, "c": 3, "d": 4, "e": 5 } } **/ ?>
