Should be like this

for($i=0;$i<=2;$i++)
{
for($j=0;$j<=2;$j++)
{
echo "enter the number $i$j<br>";
}
} 

Code (markup):

 

php is a web scripting language not desktop/console.try this type of things in C/C++/JAVA

 

make an html form, or get the data from a database ... you need to be more explicit.

 

You cant get the input directly from the user like c,c++ or java...

You should get the user input using html form controls...
<form action="" method="post">
Enter the value : <input type="text" name="input">

You can get from the PHP like this
<?php
$input=$_POST['input'];

 

Should work fine on console (which I assume you are using since you original code was using \n for newlines):

<?php
$matrix = array();
for ($i=0; $i <= 2; $i++) {
    for ($j=0; $j <= 2; $j++) {
        echo PHP_EOL . "Enter the number for [$i][$j]:";
        $line = fgets(STDIN);
        $matrix[$i][$j] = trim($line);
    }
}
