PHP executes external commands with anti-apostrophe
For example:
Echo ' WhoAmI ';
Export the database, the folder to be imported must have writable permission, the content after-u-p must be written next to each other
The code is as follows:
Echo ' mysqldump-h localhost-u$dbuser-p$dbpwd--default-character-set=utf8 $DbName >/var/$dumpFileName ';
Other uses of anti-apostrophe

#使用反撇号, implied as a command to execute $result = ' Date '; echo " The server timestamp is: $result ";echo " ";#使用shell_exec () $result 1=shell_exec ("date"); echo " The server timestamp is: $result 1 ";?> |
The output results are as follows:
The server timestamp is: current date: 2009/06/30 Second Enter new date: (Year month day)
