increase execution time in php

We can increase it in different ways based on server

Method 1: It will work in most servers. Add this function in top of page.
ini_set('max_execution_time', 600); //600 seconds

Method 2: We can set it by using .htaccess. Adding the below line in .htaccess file. It will work almost all servers.
max_execution_time 600

Method 3: If it is localhost. Open php.ini file and this word ('max_execution_time') where you can see like this by default max_execution_time = 30. You can change that 30 to your required based on your execution time for example (600) after that you have to restart the apache server.

mysql command line windows

It is working for me like this

Set the path in command line to \mysql\bin i.e (in which directory mysql is installed)

For eg: (I had tried this one in localhost)


C:\AppServ\MySql\bin>

then enter a command mysql -u root -h localhost -p and "Press Enter" then it will ask for a password, then enter your password and "Press Enter" Then you got a message like this "Welcome to mysql moniter............... " like this

For testing type a command "Show databases;" without double Quotes now you can see the databases

$tmp = substr($string, $num, 1);
$randval = $randval.$tmp;
}
echo $randval.uniqid();
}
random_code();
