change using str_replace then parse php

[chris]

ok - please forgive me if i dont make sence - ill try to explain what i want
to do

i have an file that i want to change a few srings in it (its a .htm file)

i use the str_replace funtion to replace the nessasary strings - i then want
to include the result in the php file that is doing the changes.

this is what i have got

MY index.php file is as per below
------------------
<?PHP
$file=implode("",file("main.html"));
$file=str_replace("$stringToFind","$NewString", $file);
echo $file;
?>
--------------------

but this doesnt parse any php that is in $file

i thought a way around this would be to save $file as say file.tmp and then
use an include statement to include this. then delete file.tmp

is there any other way around it

thanks

[chris]

i have worked it out - i used the output buffering .

Use eval:

<?PHP
$file=implode("",file("main.html"));
$file=str_replace("$stringToFind","$NewString", $file);
eval( '?>' . $file . '<?php' );
?>

N.B. eval should be avoided at all costs it's "expensive"

Nothing "should be avoided at all costs" even if it's expensive. It only has
to be used wisely. (Speed and memory optimization is not the main goal
of every coding.)

PS.: My code should be: eval( '?' . '>' . $file . '<' . '?php ' );

In fact you should read "should only be used as a last resort". Fortunate,
the OP did find a better solution using output buffering.

Well ok, I meant unless there is no other solution, just worded it
badly, and one of the comments on the function page contains the quote

wrong question. -- Rasmus Lerdorf, BDFL of PHP"

It's also bad programming, in my experience. I've never seen or even heard
of a good reason for using it, where some extra coding couldn't do the job
much faster. I'm not criticising, just expressing my opinion :)
