Replacing select text in strings?

Is there a way I can have php sort though text, and replace any matching text blurbs, with another text blurb?

Ie replace any [tagsLikeThis]

With <this><this></and></this>

Can do something like this

<?php
$str = "weeeeee";

$tags[0] = "/[tag]/";
$tags[1] = "/[\/tag]/";

$replaced[0] = "<b>";
$replaced[1] = "<\/b>";

echo preg_replace($tags,$replaced,$str);
?>

Thank you!

So, if I ran an entire imported html doc through as $str, would it find and replace every [tag] like that?

it should do, but I've probably just put my foot in it now :p Too tired to think lol

Thank you for the help! :thumbsup:

Okay... Thers a problem.

<?php
$str = {include("document.htm")};

$tags[0] = "//";
$tags[1] = "//";

$replaced[0] = "<hr color=\"green\">";
$replaced[1] = "<hr color=\"black\">";

echo preg_replace($tags,$replaced,$str[-1]);
?>

That's my code.

I'm trying to convert document.htm (The link works) into a string.

But it says theres a syntax error on line 2 ($str = ... ... tm"]};), and when I take it away so its correct grammar, it say's that the function is wrong, and the reason is "t"

Argh...:confused:

you can't assign an include like that (without output buffering etc)


<?php
$str = file_get_contents("document.htm") ;
?>
or for older php versions
<?
$str = implode( '' , file("document.htm") ) ;
?>

In the script:

<?php
$str = file_get_contents("document.htm");

$tags[0] = "//";
$tags[1] = "//";

$replaced[0] = "_";
$replaced[1] = "<hr color=\"black\">";

echo preg_replace($tags,$replaced,$str);
?>

when it runs, I get this:

Warning: Unknown modifier 't' in /home/sites/site5/web/hypertestfolder/hypercodetest.php on line 10
<_i_le>Un_i_led Documen_ hyper_____op HELLO!

I replaced the pervious HR codes in the first replacement array, with "_" codes. so I could more easily see what was happening.

Basically, it went though and found the LETTERS in the tag section, instead of looking for the whole quote.

So instead of finding "[tag]" it looks for: [, t, a, g, /, and ].

Is there a way to correct this?

Sorry, I should've checked. The forum's stripped my backslashes out my post.


<?php
$str = file_get_contents("document.htm");

$tags[0] = "/\\[tag]/";
$tags[1] = "/\\[\\/tag]/";

$replaced[0] = "_";
$replaced[1] = "<hr color=\"black\">";

echo preg_replace($tags,$replaced,$str);
?>


That'll work now
