php pseudo tags preg replace

[optikalefx]

so ive done this once before, but its a lil different this time

 

I want the user in my text box to type in this

<link to phil.php displays_as Philosophy<end link>

 

and i want it to translate into

<a href='http://www.robbertlaw.com/phil.php'>Philosphy</a>

 

heres the code so far that doenst work.

//create link tag
$patterns2[0] = "/<link to ";
$patterns2[1] = "/<end link>/";
$patterns2[3] = " displays_as ";
$replacements2[0] = "<a href='http://www.robbertlaw.com/";
$replacements2[1] = "</a>";
$replacements2[3] = "'>";

 

$string = preg_replace($patterns2, $replacements2, $string);

 

 

i thought that it would replace each item and then whats leftover (i.e phil.php) would be in the same spot, just with the switched words/tags.

 

i got it to work with <heading>text</end heading> into <div id="head">text</div>

 

so im not sure why this one wont work.

any ideas?

 

btw. Thank you guys so much for helping me with all you did, iv had like 5 topics lately and I really appreciate this forum and you guys who love to help, I will contribute to the helpage when i know more about php, i help a lot on flash actionscript forums, so now i know how it feels to be helped versus helping, and I just wanted to say thanks.

[clearstatcache]

[optikalefx]

...that is the complete code. and i posted the error.

 

Error:

PHP Parse error:  syntax error, unexpected T_STRING in /hermes/web04/b1609/pow.4ten/htdocs/php/regex.php on line 12

 

code:

<?
$string = "<link to phil.php displays_as Philosophy<end link>";
print "$string\n";
$patterns2[0] = "/<link to /";
$patterns2[1] = "/<end link>/";
$patterns2[3] = "/ displays_as /";
$replacements2[0] = "<a href='http://www.robbertlaw.com/";
$replacements2[1] = "[/url]";
$replacements2[3] = "'>";

foreach($patterns2 as $key => $regex) {
    $string = preg_replace($regex, $replacements2[$key], $string);
}
print "$string\n";
?>

 

 

this should display a simple hyper link that shows as Philosphy, and links to http://www.robbertlaw.com/phil.php.

i run ds code..

<?

$string = "<link to phil.php displays_as Philosophy<end link>";

print "$string\n";

$patterns2[0] = "/<link to /";

$patterns2[1] = "/<end link>/";

$patterns2[3] = "/ displays_as /";

$replacements2[0] = "<a href='http://www.robbertlaw.com/";

$replacements2[1] = "[/url]";

$replacements2[3] = "'>";

 

foreach($patterns2 as $key => $regex) {

    $string = preg_replace($regex, $replacements2[$key], $string);

}

print "$string\n";

?>

 

and the output is

<link to phil.php displays_as Philosophy<end link>

<a href='http://www.robbertlaw.com/phil.php'>Philosophy[/url]

This works for me:

 

<pre>
<?php
$string = "<link to phil.php displays_as Philosophy<end link>";
print "$string\n";
$patterns2[0] = "/<link to /";
$patterns2[1] = "/<end link>/";
$patterns2[3] = "/ displays_as /";
$replacements2[0] = "<a href='http://www.robbertlaw.com/";
$replacements2[1] = "</a>";
$replacements2[3] = "'>";
    $string = preg_replace($patterns2, $replacements2, $string);
print "$string\n";
?>
</pre>
