$_GET( )

[jx2012]

Hi there,

 

I am new to this forum want to say Hi  to everyone  .

I just learn a little bit of PHP. I couldn't figure this out. Could someone please help me? Many thanks.

 

1. when I ran the 1st code below, it showed me "thank you" in the browser.

    <?php

    $title=$_GET[title];

    echo $title;

    ?>

 

2. when I ran the 2nd code below, I got what I wanted.

    <?php

    $sql = "SELECT * FROM mytable WHERE title='thank you' ";

    ...

    ?>

 

3. when I ran the 3rd code below, it showed me a blank page  .

    <?php

    $title=$_GET[title];

    $sql = "SELECT * FROM mytable WHERE title='<?php echo $title; ?>' ";

    ...

    ?>

 

How to make the 3rd code work like the 2nd one? It seems a php code under php is NOT working.

If you're in PHP, you can't go further into php. You'll need to concatenate.

// with the concatenate operator:
$sql = "SELECT * FROM mytable WHERE title='" . $title . "' ";

// or even shorter (only works in double quotes):
$sql = "SELECT * FROM mytable WHERE title='$title' ";

Hehe you are awesome. It works. I just though title!='$title' because $title is a string. I was wrong. Thanks so much!
