I've seen other examples using regex however I'm a little bit troubled trying to format mine correctly, I'll have a list of numbers like this:
1.0.0.1ACS
1.0.0.2ADS
1.0.1.8AAB
However I only want to have the actual 4 numbers but the numbers could turn into multiple digits per line for example 122.222.222.222 (up to 3) how would I go about using PHP to do this? I presume I would have to put them all into a array first then for each in array, then I am confused on how to remove the extra letters.
Thanks in advance!
Yours Code is:
<?php
$input = <<<TEST
1.0.0.1ACS
1.0.0.2ADS
1.0.1.8AAB
TEST;
if (!preg_match_all("#(\d{1,3}.\d{1,3}.\d{1,3}.\d{1,3})+#", $input, $matches))
print("NOT FOUND!");
else
var_dump($matches[0]);

I've been looking around for some help, but haven't found my solution yet. The problem is a lot like this one: Extract address from string
But I cannot seem to rewrite the php code to solve my problem.
I'm using Magento and I have only 1 address field combining streetname and housenumber. For my CSV export I'm using a XSLT extension, which can work with PHP also. For retrieving the address and importing, I need streetname and housenumber to be 2 strings.
At this moment I'm using:
preg_replace('/[0-9,.]/','',$address);
for retrieving the street,
and:
preg_replace('/[^0-9,.]/','',$address);
for retrieving the housenumber. And... this just doesn't work in a lot of situations. Because sometimes a number is included in the streetname (like 2nd street) or a character is included in the housenumber (like 36-B).
The only 2 things we always know are "A housenumber always includes a number" and "A housenumber (sometimes including characters) is always at the end of the string"
I've made an image of a few examples:
Examples
You will have to search for the last number in the string. Than the first space before that, and split it at this position
I found the following code to work almost perfect.
static function addressFix($address){
$r = strrev ($address);
$str1= preg_replace('/^(.*?\d+)(.*?)$/', '$2', $r);
return strrev($str1);
}
static function houseNumberFix($address){
$r = strrev ($address);
$str2= preg_replace('/^(.*?\d+)(.*?)$/', '$1', $r);
return strrev($str2);
}
im having an issue with preg_match_all. I have this string:
$product_req = "ACTIVE-6,CATEGORY-ACTIVE-8,CATEGORY-ACTIVE-4,ACTIVE-9";
I need to get the numbers preceded by "ACTIVE-" but not by "CATEGORY-ACTIVE-", so in this case the result should be 6,9. I used the statement below:
preg_match_all("/ACTIVE-(\d+)/", $product_req, $this_act);
However this will return all the numbers because all of them are in fact preceded by "ACTIVE-" but thats not what i meant because i need to leave out those preceded by "CATEGORY-ACTIVE-". How can i configure preg_match_all to do it? Or maybe there is some other function that can do the job?
EDIT:
I tried this:
preg_match_all("/CATEGORY-ACTIVE-(\d+)/", $product_req, $this_cat_act);
preg_match_all("/ACTIVE-(\d+)/", $product_req, $this_act);
$act_cat = str_replace($this_cat_act[1],"",$this_act[1]);
it kinda works, but i guess there is a better and cleaner way to do it. Besides the output is kinda weird too.
Thank you.
Hi I'm using php to program my site and I've been reading loads about preg_match and trying lots of examples. What I'm trying to do is something like below...
if(preg_match('These characters'), $myVariable, matches)){
Find and remove found characters from $myVariable;
}
I'm pretty sure this is obvious to php experts but it's had me stuck after hours of trying and reading.
Thanks in advance
You don't need to check for a match before doing a replace. It's like if you were to do:
str_replace("A","B","ZZZZZZZ");
It just won't replace anything. Same goes for preg_replace: If there is no match, it just does nothing.
It sounds like you should be using preg_replace. If you wanted to remove all y's and o's for example you would do this:
$string = 'hey you guys!';
$ans = preg_replace('/[yo]/','',$string);
print_r($ans); //outputs 'he u gus!'
Whatever characters you want to remove, just put them between the brackets [...]
I've been working on this simple script all day trying to figure it out. I'm new to regex so please keep that in mind. On top of that, I've tried just about anything and everything I could to get this to work.
I'm trying to (to learn, please don't point me to the API) download a TSV file from Yahoo Site Explorer via either cURL or file_get_contents (both work, just messing with different things) and then using regex to get only the URL column to appear. I realize I might have more luck with other functions, but I can't find anything dealing with TSV and now it's become a challenge. I've literally spent the entire day trying to get this correct.
So a URL would be:
https://siteexplorer.search.yahoo.com/search?p=www.google.com&bwm=i&bwmo=&bwmf=s
And my regex currently looks like this (I know it's horrible...it's probably the millionth attempt):
preg_match_all('((http(s?)://?(([^/]+(\/.+))))^[\t]$)', $dl, $matches);
My issue right now is that there's 4 columns. TITLE URL SIZE FORMAT. I'm able to strip out everything from the first column (TITLE) and the last (FORMAT) column, but I cannot seem to strip out the SIZE column and get rid of the last slash in case the sites linking in don't have that last slash.
Another thing - I've actually accomplished getting JUST the URL to appear, but they all had ending slashes which leave out links from, say, Twitter.
Any help would be greatly appreciated!
Don't know much about PHP, but this regex works in python (should be the same in PHP):
".+?\t(.+?)\t.*"
Just match it and get the content of group 1. FWIW, code in Python:
import re
import fileinput
urlre = re.compile(".+?\t(.+?)\t.*")
for line in fileinput.input():
m = urlre.match(line)
if m:
print m.group(1)
Personally, I'd split the lines by tab. For example:
$stuff = file_get_contents($url);
// split the whole file by newlines, to get an array of lines
$lines = explode("\n", $stuff);
// loop through the lines
foreach ($lines as $line) {
// split by tab
$parts = explode("\t", $line);
// put the URLs in a list
$urls[] = $parts[1];
// or keep track of them by title
$urls[$parts[0]] = $parts[1];
// or whatever...
}
Just use parse_url or parse_str instead. Always try to find anything else than regular expressions which are extremely slow.
Calling all the PHP helpers out there.
So basically I would like to give the function preg_match a variable that can contain a couple thousand lines of code) and have it search using a wildcard + strings either side of the widlcard.
For example I would like to search for strings that look like this <a href="*.pdf">
I would then like the function to return every match (along with the html shiz around the wildcard, this is to catch any directory structures too) in an array that I can loop through using a foreach(){} loop.
I'm guessing this is possible, would anyone have the time to help me with this?
I've check through all the preg_match lit' and through the answers on here, but I can't seem to get the patterns correct. Thanks in advance.
Peace out.
unset($matches);
preg_match_all('/<a href="[^"]+\.pdf">/',$text,$matches);
foreach ($matches as $match)
{
$shiz = $match[0];
// Your code here ...
}
