Please help me with this simple script

Hello,

I'm new to unix but i would like to learn it step by step. Looks more complicated than php but i still want to give it a try.

I want to write a script to print the number and the value of the variables that match the string written from the keyboard.

I know how to do it in PHP and here is the code. Some tips would be usefull.

Thank you in advance.

The PHP looks like this:

Code:

I want to write a script to print the number and the value of the variables that match the string written from the keyboard.

Number of variables that appear in the string is 3.
Variables that appear in the string are: write, script, print

PHP Code:


<?php

//The string

$string= "I want to write a script to print the number and the value of the variables that match the string written from the keyboard.";



//Print the string

echo $string;



// Add the <br /> tag to look nice

echo "<br /><br />";



//This is the array with the words

$array = array("write","script","print","i dont exist");



//With the string, we can split it into a array, with each element containing a different word. We use the explode function for this.

$split = explode(" ", $string);



//This is the number of words found variable, if we find a word we can add 1 to it.

$numWordsFound = 0;



//This array will store the found words.

$wordsFound = array();



//Now we need to loop through all the words in the $split array. We can do this with a foreach() loop

foreach($split as $word){

    //Now we need to check if $word is in the $vars array of words.

    if(in_array($word, $array)){

        //Yes, the word is in.

        //Add it to the words found array.

        $wordsFound[] = $word;

        

        //Now add 1 to the number of words found.

        $numWordsFound += 1;

    }

}



//Now display the information. We use the implode() function on the $wordsFound array to seperate each element with a comma.

echo "Number of variables that appear in the string is " . $numWordsFound . ".<br>";;

echo "Variables that appear in the string are: " . implode(", ", $wordsFound) . ".";

?>
