escape the <?phptag

[gravityboy]

I have a search and replace script and I want to replace actual php code on the pages it's going to search but I think the php tag and code gets excuted so it won't work. Does anyone know how to escape the tag itself?

 

part of the code below, the part that has

<A href="def">Replacement HTML code</A>

I would need to be something like...

<?php Replacement php code  ?>

 

===============

 

$search = "search text";

$replace = "replace text";

 

// Or uncomment this below lines if You want replace HTML codes.

// "MARKER" can by any other string. It's only a marker.

// This marker tells PHP where ends the string.

/*

$search = <<<MARKER

<A href="abc">HTML code You want to search</A>

MARKER;

$replace = <<<MARKER

 

***need php here***

 

<A href="def">Replacement HTML code</A>

MARKER;

*/

Ok... the issue is in how you have the PHP laid out...

 

All php has to fall between the <?php and ?>... so you need to move the ?> to reflect that...

Placing PHP code within strings wont get executed. However you'll need to escape variables though. Example code

 

$source = <<<CODE
<?php
\$var = 'some value';

echo strtoupper(\$var);

?>
CODE;

// do something with $source
echo $source; // outputs the code typed above

 

To execute code within a string you'll need to use eval

I don't want it to get excuted.

 

It is a php script that searches other php pages and replaces stuff.

But I want to replace php code on the pages without the code getting run during the replace function.

In that case the example code you posted should work fine. Just make sure you escape all your variables (as I demonstrated above) within the code you're search/replacing.

 

As I said before PHP wont execute code defined within strings. Only variables.

thanks, maybe the variables was the problem, I'll test.

Or if outside the current tags and you don't want it to be executed: just use < for < and > for >

This works great but I found out by accident.

If I try to search and replace something that was already on my server it doesn't work. The pages on the server were originaly text files that I added header and footer code to then changed the extention to php. These won't allow search and replace.

 

I copied a whole directory to my c drive to make a test folder then uploaded it back by itself to the server and it works.

 

So the question is... are the pages that were ftp'd back and forth somehow changed?  Whitespace? line return? what could be the problem?
