    Unhappy Problem with displaying images using variable in php

    I am using this syntax in php to display a picture.


    $picture='<img src="$pict" >';

    echo '<td>' . $picture . '</td>';

    but it does not work yet if I use


    $picture='<img src="photoids/1368.jpg" >';

    echo '<td>' . $picture . '</td>';

    the picture is displayed.
    But I want to use different values of the image number to display different pictures in the table.

    Can you help me sort out the above code used in php.

    It's our use of quotes and variables inside them.

    To put it simply, you can't use a $Variable inside 'single quotes' and expect PHP to replace it. You can only use a $Variable inside "double quotes". If you need to use " inside double quotes then you need to escape it like this:

    $picture = "<img src=\"$pict\" >";

    The \ tells PHP that the character following should be ignored and treated the same as the rest.

    See the link in my signatures about quotes for a more indepth explanation.
    See my new CodingForums Blog: http://www.codingforums.com/blogs/tangoforce/

    Many useful explanations and tips including: Cannot modify headers - already sent, The IE if (isset($_POST['submit'])) bug explained, unexpected T_CONSTANT_ENCAPSED_STRING, debugging tips and much more!
