url的语法使用url中的变量

Question

I have the following script in php:

<?php

$my_array_of_vars['v'];

    $row['comment'] = "<img src='http://img.youtube.com/vi/xxxxxx/hqdefault.jpg' title='YouTube Video' alt='YouTube Video' /> ";

?>

All I want is to replace the "xxxxxx" with the result in variable $my_array_of_vars['v']; I have tried a lot of things but always getting wrong result. Any idea how to do this please?

This is what I have tried:

<?php
    $row['comment'] = "<img src='http://img.youtube.com/vi/$my_array_of_vars['v']/hqdefault.jpg' title='YouTube Video' alt='YouTube Video' /> ";
?>

Answer 1

You could use those fancy brackets {} like this:

$row['comment'] = "<img src='http://img.youtube.com/vi/{$my_array_of_vars['v']}/hqdefault.jpg' title='YouTube Video' alt='YouTube Video' /> ";

or properly concatenate the variable to the string:

$row['comment'] = "<img src='http://img.youtube.com/vi/".$my_array_of_vars['v']."/hqdefault.jpg' title='YouTube Video' alt='YouTube Video' /> ";
