6、抓取显示网页源代码
maxframes=5000; //抓取多少个字节可以自行设置 $snoopy->fetch("http://www.jlu.edu.cn/"); echo "
\n"; for($i=0;$imaxframes;$i++){ echo htmlentities($snoopy->results[$i]); } echo "

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.
