Search for occurrences in string

The_Chancer

I am trying to get information out of a string, and replace it.

The text will always have the format of

src="cid:325236hdjfgks34563@name"

There can be multiple occurrences though, and what I need to change the string to will also vary.

Is there any way of going through a string, looking for this.

The changing of it will be done by stripping off the front src="cid: and everything after the @ leaving the ID only (for content-id for web based e-mail inline images) that bit I can do.

In other words... flow like this..

Search in string for src="cid:43253453@name"

Found !! -> stop and replace

Carry on searching, stopping and replacing until end of string.

One option I have thought of is writing a temp text file and doing it line by line, but is there a better way ?

Any thoughts / suggestions ?

preg_replace can do this for you.

Can it get the part of the string, compare it with another part, if so, then change it over, else try the next part ?

Ahh...

If I go the other way and use the str_replace with the replace string as the request, I can change it that way....

Think I have sorted it...

Thanks Eric... 😃

Sometimes thinking about a problem releases the answer.

The lazy man can always find and easier way to do anything.

Just a little code snippet to explain...

				for($i=1; $i< count($struct->parts); $i++) {
					$id=substr($struct->parts[$i]->id,1,-1);
					foreach($struct->parts[$i]->parameters as $attr)
					if(strtolower($attr->attribute) == 'name') {
						$filename = $this->decodeHeader($attr->value);
						break;
					}
					$arr["body"]=str_replace("src=\"cid:".$id."\"","src=\"viewimage.php?uid=".$this->msg_uid."&part=$i&filename=$filename\"",$arr["body"]);
				}

It's a bad penny... not a monkey...
