'<img '.$imgarr[1][$k].'>' : '<img '.$imgarr[1][$k].' />'; $content = str_replace("WAP-IMG::{$k}", $attstr, $content); } } $content = preg_replace("/&[a-z]{3,10};/isU", ' ', $content); return $content; } function text2wml($content) { $content = str_replace('$', '$$', $content); $content = str_replace("\\r\\n", "\\n", htmlspecialchars($content)); $content = explode("\\n", $content); for ($i = 0; $i < count($content); $i++) { // 过滤首尾空格 $content[$i] = trim($content[$i]); // 如果去掉全角空格为空行,则设为空行,否则不对全角空格过滤。 if (str_replace(" ", "", $content[$i]) == "") $content[$i] = ""; } //合并各行,转化为 WML,并过滤掉空行 $content = str_replace("<p><br /></p>\\n", "", "<p>".implode("<br /></p>\\n<p>", $content)."<br /></p>\\n"); return $content; } ?>

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
