Question

I want to replace this code:

$html=<<<EOF

    <p>{${$var[i]}[name]}</p>
    <p>{${$var[i+1]}[name]}</p>
    <p>{${$var[i+2]}[name]}</p>
    <p>{${$var[i+3]}[name]}</p>

EOF;

with something like this:

$html=<<<EOF

    <p>{${$var[new_i]}[name]}</p>
    <p>{${$var[new_i]}[name]}</p>
    <p>{${$var[new_i]}[name]}</p>
    <p>{${$var[new_i]}[name]}</p>

EOF;

and preserve functionality of the first piece of code.

Is it possible or not?

Answer 1

Post-Increment to the rescue!

$html=<<<EOF

    <p>{${$var[$i++]}[name]}</p>
    <p>{${$var[$i++]}[name]}</p>
    <p>{${$var[$i++]}[name]}</p>
    <p>{${$var[$i++]}[name]}</p>

EOF;

Although if you are just going to display $html right after this, it might be better to do:

<?php for($i = 0; $i < $max_i; ++$i):?>
<p><?php echo ${$var[$i]}[name] ?></p>
<?php endfor;?>
