Adding a block of text into a specific location of a file.

**AbelaJohnB** · Mar 18, 2002 00:35

Hello.

I have a bock of text inside an existing varable.

$text = "this is just a random block of text";

Then I have another file:

PHP Code:


<html>

<head>

<title>Untitled Document</title>

<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

<script><!-- The Scrolling Message Java Applet -------------------- 



function scroll_status (sval){ var msg = "_INSERT_VARIABLE_TEXT_HERE"; var out = " "; var c = 1; if (150 < sval) ......setTimeout("scroll_status(150)",25); } }}// -- End of JavaScript code -------------- --></script>



</head>



<body bgcolor="#FFFFFF" onload="tmx1a=window.setTimeout('scroll_status(100)',50);" >

Now, what I need is to add the block of text $text; into the above code where: _INSERT_VARIABLE_TEXT_HERE is.

Can someone please advise me on how to accomplish this.

Thank You.

i'm probably misunderstanding you but wouldn't a plain echo work or if not you can use something like how templates work...

this seems something you can easily do John so i'm fairly sure i'm on the wrong track here

... at least i could get you to clarify

Hello.

I guess I did a terriable job explaining things....

The first variable (the block of text) is being generated by a different file. (generate.php)

So, this file (generate.php) has to somehow open the other file (footer.php - code listed above) and shove the variable (block of text) into the 'footer.php' file, at the specific place I indicated.

Sorry, forgot to mention I was working with two seperate files, and one of them is a flat-file. (footer.php)

Thanks.

Hi there!

I just thought, if your file you need to modify is a php-file, then just make an output of some variable in the right place, but first, prepend the initialization of that variable.
Ex:

PHP Code:


<?

$your_var="something"; //put it here

...

...

...

print("$your_var"); //output in the right place



?>

I've meaned that inserting a line of text into a 2nd line of a file is easier then inserting a text into specific position

Hello.

Ok, here is what I am trying to do.

I have a file called: news.txt

Code:

<a name="newsitem1016416793,68681,"></a>
Subject1:This is the text input for number one.<br><br>

<a name="newsitem1016415492,28443,"></a>
Subject2:This is the text input for number two.<br><br>

<a name="newsitem1016337268,49011,"></a>
Subject3:This is the text input for number three.<br>

I need to do three things:

1) REMVOE the entire line where <a name=XX></a> is

2) Replace: SubjectX: WITH *news*

3) Save it to a new file called: news_clean.txt

Thank You.

Hi!

PHP Code:


<?php



$test = '<a name="newsitem1016416793,68681,"></a>

Subject1:This is the text input for number one.<br><br>

<a name="newsitem1016415492,28443,"></a>

Subject2:This is the text input for number two.<br><br>

<a name="newsitem1016337268,49011,"></a>

Subject3:This is the text input for number three.<br>';



$test1 = preg_replace("/<a[^>]*>(.*)<\/a>/siU", "", $test);

$test1 = preg_replace("/Subject\d+/", "*news*", $test);



echo $test1;



$fp = @fopen("./news_clean.txt", "w");

flock($fp, LOCK_EX);

fwrite($fp, $test1);

flock($fp, LOCK_UN);

fclose($fp);

?>

The first regexp removes the <a ... line and the second replaces subject with news

And output will be:

Code:

*news*:This is the text input for number one.

*news*:This is the text input for number two.

*news*:This is the text input for number three.

Hey Chris.

Thanks for the code.

However, it throws an error:

PHP Code:


Warning: Unknown modifier 'a' in /home/xx/test.php on line 11

Line 11 is:

PHP Code:


$test1 = preg_replace("/<a[^>]*>(.*)</a>/siU", "", $test);

Any further ideas?

I am sure Chris82's code would work - it just needs to escape the forward slash that closes the anchor tag, like this:

PHP Code:


$test1*=*preg_replace("/<a[^>]*>(.*)<\\/a>/siU",*"",*$test);

I know why his code didn't work - the same happened to my post - the back slash was eliminated, so it needs to be escaped itself. Hence the edit.
