PHP cli getting input from user and then dumping into variable possible?

Viewed 69 times

Is it possible to get input from a user using php cli and then dump the input into a variable and then the script goes ahead.

Just like the c++ cin function ?

Is that possible if yes then how ? Maybe not only php but maybe with some linux commands ?

Have a look at this PHP manual page http://php.net/manual/en/features.commandline.php

in particular

<?php
echo "Are you sure you want to do this?  Type 'yes' to continue: ";
$handle = fopen ("php://stdin","r");
$line = fgets($handle);
if(trim($line) != 'yes'){
    echo "ABORTING!n";
    exit;
}
echo "n";
echo "Thank you, continuing...n";
?>

 You can do that simply by introducing if else statement
 $where  = "";
 //receive filter option  example $_GET['week']  
  //Do some sanitizing for $_GET['week']
  if ($_GET['week']) {
  $where  =  "WHERE Test_Database.Week = $_GET['week']"
 } else if (somecondition) {
  $where  = "some query";
  }

//You can add multiple condition by concatenating $where, but make sure where not repeats

$query = "SELECT TOP 10 Test_Database.Distributor, Test_Database.Value
FROM Test_Database
$where  
GROUP BY Distributor
ORDER BY Value desc "

Here's what worked best for me when trying to script this (in case anyone else comes across this like I did):

$ pecl -d php_suffix=5.6 install <package>
$ pecl uninstall -r <package>

$ pecl -d php_suffix=7.0 install <package>
$ pecl uninstall -r <package>

$ pecl -d php_suffix=7.1 install <package>
$ pecl uninstall -r <package>

The -d php_suffix=<version> piece allows you to set config values at run time vs pre-setting them with pecl config-set. The uninstall -r bit does not actually uninstall it (from the docs):

vagrant@homestead:~$ pecl help uninstall
pecl uninstall [options] [channel/]<package> ...
Uninstalls one or more PEAR packages.  More than one package may be
specified at once.  Prefix with channel name to uninstall from a
channel not in your default channel (pecl.php.net)

Options:
  ...
  -r, --register-only
        do not remove files, only register the packages as not installed
  ...

The uninstall line is necessary otherwise installing it will remove any previously installed version, even if it was for a different PHP version (ex: Installing an extension for PHP 7.0 would remove the 5.6 version if the package was still registered as installed).

Does MySQL automatically escape their output or something like that, or should I escape in the second query as well?

You need to escape in the second query as well. MySQL does not do any escaping on its output.

Long answer: MySQL string escaping does not modify the string that is being inserted, it just makes sure it doesn't do any harm in the current query. Any SQL injection attempt still remains in the data.

Never used any of those, but they look interesting..

Take a look at Gearman as well.. more overhead in systems like these but you get other cool stuff :) Guess it depends on your needs ..
