Replace string in file using PHP
Once the file is replaced we can use PHP to save the file as well. A very simple example. Here test_file.php is the php file which contain an IP address (127.0.0.1) and I am going to replace that IP address from 127.0.0.1 to 127.1.9.9 , Once that is replace we are using fwrite() function in PHP to save the replaced file with the new IP address.
//read the entire string $str=implode("",file('../test_file.php')); $fp=fopen('../test_file.php','w'); //replace something in the file string, here i am replacing an IP address from 127.0.0.1 to 127.1.9.9 $str=str_replace('127.0.0.1','127.1.9.9',$str); //now, save the file fwrite($fp,$str,strlen($str));
