[help] eval function with two dimension array

unisabilly

Hi there ~
I have a question about eval function, i'm trying to read a tpl file line by line and convert the output to html, everything works fine except if the tpl contains two dimension array of variable my eval function fails to read the variable, following is an example :

$temp["name"]["first"] = "Michael";
$temp["name"]["surname"] = "Lee";
$compile_line ='my name is $temp[name][first]';
eval("\$compile_line=\"$compile_line\";");
echo $compile_line;

the eval function here can work with any variables even with array but not with two dimention array !!
and please if you can explain how the eval function works, coz i just know the above eval function can read the variable out of a line, but does not know how it works ~
Thanx ~ :o

eval() reads a string as PHP code. That's how it works. I can't really understand what your problem is aside from that.

sorry i didnt make it clear, I'm trying to read a tpl file and output it to php(html) format, but with the eval function that i used, it didnt work with two dimension array.

for example the tpl might look like following(test.tpl):

<table>
<tr>
<td> my name is $temp['name']['first'] </td>
<td> i'm $temp['name']['age'] </td>
</tr>
</table>

the php file might look like following (test.php):

.
.
.
$temp['name']['first'] = 'Michael';
$temp['name']['age'] = '20';
$original_file_array= file("test.tpl");
$file_size = sizeof($original_file_array);
$structure_counter = 0;

while($file_size > $structure_counter)
{
        $compile_line = $original_file_array[$structure_counter];
        eval("\$compile_line=\"$compile_line\";");
        echo $compile_line;       

        $structure_counter++;
}

hope this can demonstrate the question more clearly 😃

eval() is much simpler to understand and use if whatever it is you are eval()ing looks just like a regular old file that you'd include().

Your .tpl file can look like this:
<table>
<tr>
<td> my name is <?php print($temp['name']['first']); ?> </td>
<td> i'm <?php print($temp['name']['age']); ?> </td>
</tr>
</table>

Your code can look like this:
$temp['name']['first'] = "Keith";
$temp['name']['age'] = 22;
eval(" ?> " . implode('', file("filename.tpl")) . " <?php ");
