PHP :: How Do I Replace Text In A String...

Partially Replace A String With Data From The Same String...
I'm trying to write a script to help import some old HTML files as blog post for my website, these HTML files are 300-2000 lines long. I am currently using fgets() to read the files one line at a time, clean them and write them to the database in the appropriate format once the entire article is completed.

My issue is many of the links included on these post no longer exist (some date into the '90s) and I want as part of my importing function to "fix" these links as so. Code:

String Replace
I am in the process of writing a script to process a file that is outputted by another program we are writing. We are exporting the file to a plain text file in the following format

"ID", "Title", "Filename", "AID", "arID", "size", "bit", "Freq", "Dur", "Path", "Owner", "Gr", "date"

My problem is, I need to read in each line, whoch I am currently doing with fgets and convert the above into mysql insert statements. What I was thinking that I need to to is to the above string is:-

1. Convert all " to ' using ereg_replace()
2. Addslashes to string to escape any special characters
3. Wrap with insert statement
4. Write to Database

However thinking about that process, once I addslashes, all ' will then be ' So the final insert statement would look like :-

'ID', 'Title', 'Filename', 'AID', 'arID', 'size', 'bit', 'Freq', 'Dur', 'Path', 'Owner', 'Gr', 'date'

and any other character inside some of those fields whoch are also escaped. Is this going to cause any major problems when inserting into DB?? Should I add an extra step in there some where to convert all " to someting allowed, addslashes then change the previous step back to ' for the insert statement?

String Replace

But we cannt guess the words followed by "Click here"

so i need to replace a sub string which starts with "Click here or click here" and ends with ". or !"

Replace String Using Wildcards
I am trying to remove some tags from an XML document that I do not need.

<string id="4466.8" encoding="repr">email</string>

I want to remove the whole tag for the string but keep the content in the middle, the problem is that the id changes, so is there a way to use a 'wildcard' character in the replace code to replace any character found?

$data=str_replace('<stringid="4466.8" encoding="repr">', ' ', $data);

I saw a post that /S should work for any non whitespace character, this does not seem to work though... any idea's?

Search And Replace In Text File

Eregi Search And Replace For Some Text
I'm trying to do a search and replace for some text. For example, I have a word that is 'history', I want to replace every occurence of 'history' with:

<a href="history.html">history</a>

Now, that's easy, I can do that - however, as 'history' could also be 'History', I want to ensure that the format of 'history' stays the same. For example: $strRep = 'history'

$str = eregi_replace($strRep, '<a href="history.html">'.$strRep.'</a>, $my_other_string);

That's fine - however if history is capitalised (History), then I have a problem:

$str = eregi_replace($strRep, '<a href="history.html">'.$strRep.'</a>, $my_other_string);

because the above example would lowercase History to history.

Better Method For Search And Replace In String
Here is an example of the type of string I am trying to search and replace,

Generic text about *2nothing~ in particular. Just need to *5extract certain~ characters out of the text.

I need to search the string for "*", collect the number directly after the "*", then extract the text, and watch for the "~" character to denote the end of the text.

Then the information is sent to a new function i.e. new("2", "nothing")

The new function formats the data and returns it into the original string.

Currently I am just looping through the string and replacing as I go, but I imagine their is a better and more efficient way.

Replace Every Character In A String If It Is Not Alphanumeric

Replace Part Of String In Between Two Other Parts?
I'm trying to do is an str_replace or something within only a set of other strings. What I'm doing with some text that I put into a database is added a <br> whenever the ASCI character 10 (carraige return) comes up. It's like this.
$text = eregi_replace(10, "<BR>", $text);

what keeps happening though, is that when I make an HTML table in the text, it adds a <br> to that too, and since it's inside the table, it just adds the newline to outside of the table or something and screws everything up.

So, what I want to do is only have it replace the newline with a <br> if it isn't inside of a <table></table> string. I've been all over the PHP documentation and have yet to see something that might work.

Preg_Replace, Replace Bits Of Body Text Such As 'XML' With An Acronym
I've got this:

$thebody = preg_replace("/(s¦()".$acronymsfind."()¦s)/",$acronymsreplace,$thebody);

I'm trying to replace bits of body text such as 'XML' with an acronym, but I only want to replace the specific acronyms that start with either:

I'm not doing right and I've done as much googling and php book reading but still can't do it!

Select Specific Snippet Of Text, Replace With A Database Result
I'm having some problems trying to do something; I just can't think of a way to do it. Basically, I want to search for a specific snippet of text in a body of text, then replace it with the requested database result with some thrown in HTML.

Search Through A String For Various Text
My users enter text into a database field in the form of:

this file {link:afile.pdf} is big and this file {link:another.doc} is small.
I have no idea how many times they may enter {link:xxx} into a given field.
The code we worked out (see other post below) fabulously translates the text into a hyperlink.

The problem is that no matter how often the {link:xxx} is in a given field, I only ever get the first file returned; i.e:
This file afile.pdf is big and this file afile.pdf is small.
But what I should get is, obviously:
This file afile.pdf is big and this file another.doc is small.

I need to use some kind of looping function, or a foreach type function. Does anyone have any clues? Code:

Removing Html Anchors From POST'ed Text String
I am having problems with trying to remove some tags using PHP. What I
want is to perform a search and replace on a URL, so if someone tried to
put a URL into a guestbook database, instead of the user inputting a
link as:

<a href="http://whatever.com">visit me</A>

It goes into the database as:

http://whatever.com

I have tried the str_replace() function, but doesn't seem to work. I have
also tried strip_tags() but then that just give the result:

This is the code I've written.

$AmendedComment = str_replace("<a href="", " ", $_POST['Comment']);
$FinalComment = addslashes($AmendedComment);

Checking the database and reading it out again, the first part of the URL
remains intact, so the URL is clickable - not what I want.

I've made an attempt at preg_replace() but it's difficult to get head
around trying to write a pattern.

String Of Text (Number Of Pixels / Pixel Size / Pixel Length)
If I'm putting together a list of links and I want to get add each
item one at a time inside a foreach($aNames as $sName) loop,
is there an easy way to get the number of pixels that the $aName
takes up?

For instance, in creating a set of links...

foreach($aLinks as $sLink) {
if ((pixelsize($sLink, $sFont, $iFontSize) . pixelsize($sHTML . " ", $sFont, $iFontSize)) < 400) {
$sHTML .= " " . $sLink;
} else {
$sHTML .= "<br />
" . $sLink;
}
}

The goal is to keep the whole link on one and only one line letting
the browser automatically break up any given link..
