PHP performs external command with anti-apostrophe _php tips

For example:

Echo ' WhoAmI ';

Export the database, the folder you want to import must have writable permissions, and the content after-u-p must be written next to it

Copy Code code as follows:

Echo ' mysqldump-h localhost-u$dbuser-p$dbpwd--default-character-set=utf8 $DbName >/var/$dumpFileName ';

Anti-apostrophe other usage

<?php  
  #使用反撇号, implied as a command to execute
  $result = ' Date ';
  echo "<p>the server timestamp is: $result </p>";

  echo " 
 

The output results are as follows:
The server timestamp is: current date: 2009/06/30 Second Enter a new date: (Year month)
