Database-PHP writes data to mysql. Is it blank in phpmyadmin and data is printed directly?

{Code ...} I put the project on the sae, and the database is connected. It is okay to capture the content of other webpages and write it into the database. However, when xuegong's webpage is accessed, writing the content to the database is blank in PHPMyAdmin. PHP does not prompt an error, and it is also right to print the content, that is, write...

Function makePage ($ link ){...... // when the URL belongs to xuegong. hubuelse if (strstr ($ link, 'xuegong. hubu') {$ page = curl_init (); curl_setopt ($ page, CURLOPT_URL, $ link); curl_setopt ($ page, CURLOPT_RETURNTRANSFER, 1 ); $ content = curl_exec ($ page); $ content = stristr ($ content, 'class = "title" '); $ content = stristr ($ content, 'class = "bottom" ', true); $ content = str_replace ('class = "title">', '', $ content); $ content = strip_tags ($ content, ''); $ content = stristr ($ content, 'Responsible editor', true); $ content = trim ($ content ); $ content = str_replace ("\ r \ n", "", $ content); $ content = preg_replace ('/(
  ) {2,}/', '', $ content); $ content = str_replace ('href ="', 'href = "http://xuegong.hubu.edu.cn ', $ content ); return $ content ;}// write only the key code $ content = mysql_real_escape_string (makePage ($ notice [1] [$ key]); $ SQL = 'insert ignore into php_notice (title, link, date, content) values ("'. $ value. '","'. $ notice [1] [$ key]. '","'. $ notice [2] [$ key]. '","'. $ content. '");'; mysql_query ($ SQL) or die (mysql_error ());

PHP does not prompt an error, and it is also right to print the content, that is, after writing the data to the database, it becomes a space and the encoding is UTF-8. I don't know what to ask for advice

Run the SQL statement in phpmyadmin?
No one else can tell what the problem is.
In addition, check your field type
