PHP cli getting input from user and then dumping into variable possible?
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";
?>
In this example I'm extending Devjar's example. Credits for him for example code. Last code example is simplest and safest in my opinion.
When you use his code:
<?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 should note stdin mode is not binary-safe. You should add "b" to your mode and use following code:
<?php
echo "Are you sure you want to do this? Type 'yes' to continue: ";
$handle = fopen ("php://stdin","rb"); // <-- Add "b" Here for Binary-Safe
$line = fgets($handle);
if(trim($line) != 'yes'){
echo "ABORTING!\n";
exit;
}
echo "\n";
echo "Thank you, continuing...\n";
?>
Also you can set max charters. This is my personal example. I'll suggest to use this as your code. It's also recommended to use directly STDIN than "php://stdin".
<?php
/* Define STDIN in case if it is not already defined by PHP for some reason */
if(!defined("STDIN")) {
define("STDIN", fopen('php://stdin','rb'))
}
echo "Hello! What is your name (enter below):\n";
$strName = fread(STDIN, 80); // Read up to 80 characters or a newline
echo 'Hello ' , $strName , "\n";
?>
To read a line from standard input in php CLI mode, you can do:
$fin = fopen ("php://stdin","r");
$line = fgets($fin);
On older versions of PHP STDIN
constant may also work
$line = fgets(STDIN);
To read all the content from input use:
file_get_contents('php://input');
