Reg Exp - preg_match_all reduce array result - php
This is my Reg Exp "[c]?[\d+|\D+]\s*". My input is this "c7=c4/c5*100" and the result is :
Array
(
[0] => Array
(
[0] => c7
[1] => =
[2] => c5
[3] => +
[4] => c3
[5] => *
[6] => 1
[7] => 0
[8] => 0
)
)
But what I want is:
Array
(
[0] => Array
(
[0] => c7
[1] => =
[2] => c5
[3] => +
[4] => c3
[5] => *
[6] => 100
)
)
I can't seem to get the last part working, I'm lost as what to do next - Can anyone help?
Thanks,
Paul
You specified a character class [\d+|\D+] which would match any of the specified characters. I think you meant using an or | with a grouping construct c?(?:\d+|\D+)\s* but in that case it would match c followed by either \d+ or \D so that would match the = sign right after it resulting in c= as a match and /c as a match.
Try matching an optional c c? followed by one or more digits or | match not a digit \D
c?\d+|\D
$re = '/c?\d+|\D/m';
$str = 'c7=c4/c5*100';
preg_match_all($re, $str, $matches);
print_r($matches);
That will result in:
Array
(
[0] => Array
(
[0] => c7
[1] => =
[2] => c4
[3] => /
[4] => c5
[5] => *
[6] => 100
)
)

php regex to get all int or decimal from pattern
Purpose of my code to get all take profit which has int or decimal value. writing pattern of Takeprofit will not same. Problem: i want $m[3][4] or $m[4][4] as 1.0870 but i got only 0870. i am getting this result when number starts from 1.xxxx. They are conflicting. I can not solve TP-----1.0870 and TP=1.0870 are not detected My Code: <?php $s = 'SS 1.0140 SL 1.0670 TP1 1.0870 TP 1 1.0870 TP 2 1.0870 Takeprofit1 1.0870 Take profit 1 1.0870 TP 1.0870 TP-----1.0870 TP=1.0870 TP1=1.0870 TP Open'; $p = '#\b(TP1|TP 1|TP2|TP 2|TP3|TP 3|TAKE PROFIT 1|TAKE PROFIT 2|TAKE PROFIT 3|TAKEPROFIT 1|TAKEPROFIT 2|TAKEPROFIT 3|TAKEPROFIT\|TP)(.*?)(\bOpen\b|\b(\d+(?:\.\d+)?)\b)\b#i'; preg_match_all($p , $s , $m); Result of $m: Array ( [0] => Array ( [0] => TP1 1.0870 [1] => TP 1 1.0870 [2] => TP 2 1.0870 [3] => Take profit 1 1.0870 [4] => TP 1.0870 [5] => TP1=1.0870 ) [1] => Array ( [0] => TP1 [1] => TP 1 [2] => TP 2 [3] => Take profit 1 [4] => TP 1 [5] => TP1 ) [2] => Array ( [0] => [1] => [2] => [3] => [4] => .

You may use '~\b(TAKE ?PROFIT ?(?:[1-3]|\|TP)|TP ?(?:[1-3](?!\.\d))?)\b(.*?)\b(Open|(\d+(?:\.\d+)?))\b~i' See the regex demo Details \b - word boundary (TAKE ?PROFIT ?(?:[1-3]|\|TP)|TP ?(?:[1-3](?!\.\d))?) - Group 1: TAKE, an optional space, PROFIT, an optional space, then a digit from 1 to 3 or |TP substring, or TP with an optional space after it that is optionally followed with 1, 2 or 3 that are not followed with . and a digit \b - word boundary (.*?) - Group 2: any 0+ chars other than line break chars as few as possible \b - word boundary (Open|(\d+(?:\.\d+)?)) - Group 3: Open or Group 4: 1+ digits followed with an optional sequence of . and 1+ digits \b - word boundary.
Match numbers separated with colons, semicolons optionally
I have the following string:
objectsA=38155,54,1;38155,53,1;38155,45,1;38155,47,1;38155,46,1;2000,55,1;38155,50,1;38155,49,1;38155,48,1;38155,40,1;38155,41,1;38155,42,1;38155,43,1;38155,51,1;38155,52,1;38155,44,1;38155,35,1;38155,33,1;38155,32,1;38155,34,1;38155,36,1;38155,38,1;38155,39,1;:objectsB=
And I want to know how can I match, optionally, the numbers inside objectsA and objectsB but put into consideration, that may one or another can be empty. For example:
objectsA can be:
objectsA=38155,54,1;38155,53,1;38155,45,1;38155,47,1;38155,46,1;2000,55,1;38155,50,1;38155,49,1;38155,48,1;38155,40,1;38155,41,1;38155,42,1;38155,43,1;38155,51,1;38155,52,1;38155,44,1;38155,35,1;38155,33,1;38155,32,1;38155,34,1;38155,36,1;38155,38,1;38155,39,1;
But also can be
objectsA=:objectsB=38155,54,1;38155,53,1;38155,45,1;38155,47,1;38155,46,1;2000,55,1;38155,50,1;38155,49,1;38155,48,1;38155,40,1;38155,41,1;38155,42,1;38155,43,1;38155,51,1;38155,52,1;38155,44,1;38155,35,1;38155,33,1;38155,32,1;38155,34,1;38155,36,1;38155,38,1;38155,39,1;
Or even
objectsA=38155,54,1;38155,53,1;38155,45,1;38155,47,1;38155,46,1;2000,55,1;38155,50,1;38155,49,1;38155,48,1;38155,40,1;38155,41,1;38155,42,1;38155,43,1;38155,51,1;38155,52,1;38155,44,1;38155,35,1;38155,33,1;38155,32,1;38155,34,1;38155,36,1;38155,38,1;38155,39,1;:objectsB=objectsA=38155,54,1;38155,53,1;38155,45,1;38155,47,1;38155,46,1;2000,55,1;38155,50,1;38155,49,1;38155,48,1;38155,40,1;38155,41,1;38155,42,1;38155,43,1;38155,51,1;38155,52,1;38155,44,1;38155,35,1;38155,33,1;38155,32,1;38155,34,1;38155,36,1;38155,38,1;38155,39,1;
The current code:
$line2 = "

}
echo '<pre>';
print_r($c);

And the problems is that the current regex ((\d+\,\d+\,\d\;)+|) has an weird behavior, that can't happen.

How to match an optional subpattern in the middle or end of an url depending on the existence of a filename and extension
I am trying to preg_match a url consisting of a category slug, an optional subcategory slug and an option item slug.
It works in all cases, except for the 4th case.
$urls[0] = '/main_cat_slug';
$urls[1] = '/main_cat_slug/';
$urls[2] = '/main_cat_slug/sub_cat_slug';
$urls[3] = '/main_cat_slug/sub_cat_slug/';
$urls[4] = '/main_cat_slug/item.html';
$urls[5] = '/main_cat_slug/sub_cat_slug/item.html';
$regexp = array();
$regexp[] = '/(?:(?<category>[\w]+)/?)'; // Find the main category (is always available)
$regexp[] = '(?:(?<subcategory>[\w]+)/?)?'; // Find an optional sub-category, is not always available
$regexp[] = '(?:(?<item>[\w]+)\.html)?'; // Find an optional item, is not always available (don't catch the extension)
$regexp = implode('', $regexp);
foreach($urls as $index=>$url) {
preg_match("#{$regexp}#i", $url, $matches);
echo '<pre><h1>', $index, '</h1>';
echo $url, '<br />';
echo '<br />';
print_r($matches);
}
In the 4-th case, the category will be found, but the item is empty and the subcategory gets the value op "item".
Could someone help me out, so that the 4-th case will only get a category and an item?
This is the output for above code:
0

(
[0] => /main_cat_slug
[category] => main_cat_slug
[1] => main_cat_slug
)

Description
This regex will pickout the three types of data, using the following rules:
The / is always the first character in the string
The Main_Cat is always first, it follows the first / and continues until the next /
If the first string ends in .html/ then this is a Main_Cat
if the first string ends in .html followed by the end of the string, then this is an item
The Sub_Cat is always second, it follows the second / and continues until the next /
If the second string ends in .html/ then this is a Sub_Cat
if the second string ends in .html followed by the end of the string, then this is an item
The Item type always has an .html suffix
There will never be a / after the Item
the Item type will always be the last field
^\/(?:(?<Main_Cat>(?![^\/\r\n]*\.html\s*$)[^\/\r\n]*)\/)?(?:(?<Sub_Cat>(?![^\/\r\n]*\.html\s*$)[^\/\r\n]*)\/)?(?:(?<Item>[^\/\r\n]*?)(?:\.html|$))?
If you're using this expression against individual strings then you can remove the new line characters \r\n. The resulting expression would look like: ^\/(?<Main_Cat>[^\/]*)(?:(?:\/(?![^\/]*\.html)(?<Sub_Cat>[^\/]*))?(?:\/(?<Item>[^\/]*)\.html)?)?.*?$ follows the same rules above. Note the end of line $ forces the test to match your entire string
PHP Code Example:
Source String

/main_cat_slug9/sub_cat_slug9/item9.html
Code
<?php

You can try this:
preg_match('~/(?<main_cat>[^/\s]++/?+)(?<sub_cat>[^/\s]++/?+)?'
. '(?>(?<filename>\S+?)\.html)?~', $url, $match);
print_r($match);
Note that you can access easily to the different parts with the named captures (useful to test if there is a subpattern or not.).
a question about preg_match
I have a question in PHP:
When using preg_match, why #^(([a-z]{2})/)?(([a-z\-]{3,})/(([a-z\-]{3,}))?)?$#i match ab/cde/fgh and do not match ab/cde?
(I mean:
preg_match_all('#^(([a-z]{2})/)?(([a-z\-]{3,})/(([a-z\-]{3,}))?)?$#i','ab/cde/fgh',$match)
$match = Array
(
[0] => ab/cde/fgd
[1] => ab/
[2] => ab
[3] => cde/fgd
[4] => cde
[5] => fgd
[6] => fgd
)
and
preg_match_all('#^(([a-z]{2})/)?(([a-z\-]{3,})/(([a-z\-]{3,}))?)?$#i','ab/cde',$match)
$match = Array ()
Because as the regex is written, you need a slash after the cde. ab/cde/ should match.
[a-z-]{3,} = 3 or more characters
preg_match to match an optional string, but not match all of the string
Take for example the following regex match.
preg_match('!^publisher/([A-Za-z0-9\-\_]+)/([0-9]+)/([0-9]{4})-(january|february|march|april|may|june|july|august|september|october|november|december):([0-9]{1,2})-([0-9]{1,2})/([A-Za-z0-9\-\_]+)/([0-9]+)(/page-[0-9]+)?$!', 'publisher/news/1/2010-march:03-23/test_title/1/page-1', $matches);
print_r($matches);
It produces the following:
Array
(
[0] => publisher/news/1/2010-march:03-23/test_title/1/page-1
[1] => news
[2] => 1
[3] => 2010
[4] => march
[5] => 03
[6] => 23
[7] => test_title
[8] => 1
[9] => /page-1
)
However as the last match is optional it can also work with matching the following "publisher/news/1/2010-march:03-23/test_title/1". My problem is that I want to be able to match (/page-[0-9]+) if it exists, but match only the page number so "publisher/news/1/2010-march:03-23/test_title/1/page-1" would match like so:
Array
(
[0] => publisher/news/1/2010-march:03-23/test_title/1/page-1
[1] => news
[2] => 1
[3] => 2010
[4] => march
[5] => 03
[6] => 23
[7] => test_title
[8] => 1
[9] => 1
)
I've tried the following regex
'!^publisher/([A-Za-z0-9\-\_]+)/([0-9]+)/([0-9]{4})-(january|february|march|april|may|june|july|august|september|october|november|december):([0-9]{1,2})-([0-9]{1,2})/([A-Za-z0-9\-\_]+)/([0-9]+)/?p?a?g?e?-?([0-9]+)?$!'
This works, however it will also match "publisher/news/1/2010-march:03-23/test_title/1/1". I have no idea to perform a match but not have it come back in the matches? Is it possible in a single regex?
To absolutely not match publisher/news/1/2010-march:03-23/test_title/1/whatever
!^publisher/([A-Za-z0-9\-\_]+)/([0-9]+)/([0-9]{4})-(january|february|march|april|may|june|july|august|september|october|november|december):([0-9]{1,2})-([0-9]{1,2})/([A-Za-z0-9\-\_]+)/([0-9]+)(?:/page-([0-9]+))?$!
To still match publisher/news/1/2010-march:03-23/test_title/1/whatever but ignore the /whatever:
!^publisher/([A-Za-z0-9\-\_]+)/([0-9]+)/([0-9]{4})-(january|february|march|april|may|june|july|august|september|october|november|december):([0-9]{1,2})-([0-9]{1,2})/([A-Za-z0-9\-\_]+)/([0-9]+)(?:(?:/page-([0-9]+))|/.*)?$!
maybe like that:
'!^publisher/([A-Za-z0-9\-\_]+)/([0-9]+)/([0-9]{4})-(january|february|march|april|may|june|july|august|september|october|november|december):([0-9]{1,2})-([0-9]{1,2})/([A-Za-z0-9\-\_]+)/([0-9]+)(/page-([0-9]+))?$!'
This is the regex what you are looking for:
^publisher/([A-Za-z0-9\-\_]+)/([0-9]+)/([0-9]{4})-(january|february|march|april|may|june|july|august|september|october|november|december):([0-9]{1,2})-([0-9]{1,2})/([A-Za-z0-9\-\_]+)/([0-9]+)/(?:page-(\d+))?
You can test it in rexexbuddy. If "page-1" is not set it will leave var 9 empty else it will set it.
