I have strings that looks like this:
searchUniqueCode("name", "FF14_1451_DAD4");searchUniqueCode("name", "F1F1_1451_DAD4");
searchUniqueCode("name", "FF14_3121_DAD4");searchUniqueCode("name", "SH14_1451_DAD4");
searchUniqueCode("name", "FF14_1131_DAD4");searchUniqueCode("name", "FF14_1451_D31F");
And I am trying to get all of the strings under " " after the common pattern searchUniqueCode("name", Like the FF14_1451_DAD4.
Is there any way I can achieve that using PHP?
Thank you!
Try this regex:
searchUniqueCode\("name",\s*"\K[^"]+
Click for Demo
Check code here
Explanation:
searchUniqueCode\("name", - matches searchUniqueCode\("name",
\s*" - matches 0 or more occurrences of a white-space followed by a "
\K - un-matches whatever has been matched so far and starts the match from the current position
[^"]+ - matches 1 or more occurrences of any character that is not a ". This is the desired match that will match everything until the next occurrence of "
Or
You can capture the desired values in group 1 as shown below:
searchUniqueCode\("name",\s*"([^"]+)" - Working code here

I have following problem:
I have a pattern like this:
/(?<=template=")(.*?)(.*\/)/gm
And an text like this:
template="test/widgets/glasgow.phtml"}}
My regex should search for the path infront of my file, i need to cut it out so that it will look at the end like this:
template="glasgow.phtml"}}
That works fine but the problem is that i have sometimes an text that looks like this:
block="core/template" template="test/widgets/getcallus.phtml"}}</p>
It cuts everything out till the </.
This is getting cutted out:
test/widgets/getcallus.phtml"}}</
Instead of:
test/widgets/
I have tried to limit the end with $ but it doesnt do nothing.
I am testing it on regexr.com

You may use the following pattern:
template="\K[^"\/]*\/[^"\/]*\/
See the regex demo. In PHP, you may get rid of backslashes if you specify another regex delimiter:
$regex = '~template="\K[^"/]*/[^"/]*/~';
Details
template=" - literal text
\K - match reset operator
[^"\/]* - 0 or more chars other than / and "
\/ - a / char
[^"\/]* - 0 or more chars other than / and "
\/ - a / char
It is equal to template="\K(?:[^"\/]*\/){2}, where (?:...){2} repeats the non-capturing group sequence of patterns twice.
Be careful with (.*?)(.*\/)
This pattern corresponds to a REDOS vulnerability. (There are 2^n ways to read the n chars before the last /...
To keep a regex closed to yours, you can use
/(?<=template=")([^"]*?\/)*([^"]*)"/
([^"]*?\/)* reads as many blocks "non / nor " chars followed by /" as possible.

My title probably doesn't explain exactly what I mean. Take the following string:
POWERSTART9^{{2|3}}POWERENDx{{3^EXSTARTxEXEND}}=POWERSTART27^{{1|4}}POWEREND
What I want to do here is isolate the parts that are like this:
{{2|3}} or {{1|4}}
The following expression works to an extent, it selects the first one {{2|3}} with no issue:
\{\{(.*?)\|(.*?)\}\}
The problem is, it's not just selecting the first if {{2|3}} and the second of {{1|4}} because after the first one we have {{3^EXSTARTxEXEND}} so it's taking the starting point from {{3 and going right until the end of the second part I want |4}}
Here it is highlighted on RegExr:
I've never been great with regex and can't work out how to stop it doing that. Any ideas? I basically want it to only match the exact pattern and not something that contains it.
You may use
\{\{((?:(?!{{).)*?)\|(.*?)}}
See the regex demo.
If there can be no { and } inside the {{...}} substrings, you may use a simpler \{\{([^{}|]*)\|([^{}]*)}} expression (see demo).
Details
\{\{ - a {{ substring
((?:(?!{{).)*?) - Capturing group 1: any char (.), as few as possible (*?), that does not start a {{ char sequence (tempered greedy token)
[^{}|]* - any 0 or more chars other than {, } and |
\| - a | char
(.*?) - Capturing group 2: any 0 or more chars, as few as possible
[^{}]* - any 0 or more chars other than { and }
}} - a }} substring.
Try this \{\{([^\^|]*)\|([^\^|]*)\}\}

I have a value like this 73b6424b. I want to split value into two parts. Like 73b6 and 424b. Then the two split value want to reverse. Like 424b and 73b6. And concatenate this two value like this 424b73b6. I have already done this like way
$substr_device_value = 73b6424b;
$first_value = substr($substr_device_value,0,4);
$second_value = substr($substr_device_value,4,8);
$final_value = $second_value.$first_value;
I am searching more than easy way what I have done. Is it possible?? If yes then approach please
You may use
preg_replace('~^(.{4})(.{4})$~', '$2$1', $s)
See the regex demo
Details
^ - matches the string start position
(.{4}) - captures any 4 chars into Group 1 ($1)
(.{4}) - captures any 4 chars into Group 2 ($2)
$ - end of string.
The '$2$1' replacement pattern swaps the values.
NOTE: If you want to pre-validate the data before swapping, you may replace . pattern with a more specific one, say, \w to only match word chars, or [[:alnum:]] to only match alphanumeric chars, or [0-9a-z] if you plan to only match strings containing digits and lowercase ASCII letters.
$my_string = '88888805';
echo preg_replace("/(^.|.$)(*SKIP)(*F)|(.)/","*",$,my_string);
This shows the first and last number like thus 8******5
But how can i show this number like this 888888**. (The last 2 number is hidden)
Thank you!
From this: 8******5
To: 888888**
I'm not sure if you have worked on this Regex pattern to do something unique. However, I will provide you with a general one that should fit your question without using your current pattern.
$my_string = '88888805';
echo preg_replace("/([0-9]+)[0-9]{2}$/","$1**",$,my_string);
Explanation:
The ([0-9]+) will match all digits, this could be replaced with \d+, it's between brackets to be captured as we are going to use it in the results.
[0-9]{2} is going to match the last 2 digits, again, it can be replaced with \d{2}, it's outside the brackets because we don't want to include them in the result. the $ after that is to indicate the end of the test, it's optional anyways.
Results:
Input: 88888805
Output: 888888**
echo preg_replace("/(.{2}$)(*SKIP)(*F)|(.)/","*",$my_string);
If it for a uni assignment, you'd probably want to do this. Basically says, don't match if its the last two characters, otherwise match.
I have variable strings like the below:
The.Test.String.A01Y18.123h.WIB-DI.DO5.1.K.314-ECO
The.Regex.F05P78.123h.WIB-DI.DO5.1.K.314-EYT
Word.C05F78.342T.DSW-RF.EF5.2.F.342-DDF
I would like to extract this part of these string in PHP dynamically and i was looking at using regex but haven't had much success:
The.Test.String.A01Y18
The.Regex.F05P78
Word.C05F78
And ultimately to:
The Test String A01Y18
The Regex F05P78
Word C05F78
The first part of the text will be variable in length and will separate each word with a period. The next part will always be the same length with the pattern:
One letter, 2 number, one letter, 2 numbers pattern (C05F78)
Any thing in the string after that is what I would like to remove.
that's it
$x=array(
"The.Test.String.A01Y18.123h.WIB-DI.DO5.1.K.314-ECO",
"The.Regex.F05P78.123h.WIB-DI.DO5.1.K.314-EYT",
"Word.C05F78.342T.DSW-RF.EF5.2.F.342-DDF"
);
for ($i=0, $tmp_count=count($x); $i<$tmp_count; ++$i) {
echo str_replace(".", " ", preg_replace("/^(.+?)([a-z]{1}[0-9]{2}[a-z]{1}[0-9]{2})\..+$/i", "\\1\\2", $x[$i]))."<br />";
}
Using this regular expression should work, replacing each of your strings with the first capturing group:
^((?:\w+\.)+\w\d{2}\w\d{2}).*
See demo at http://regex101.com/r/fR3pM6
This is valid too:
preg_match("\.*[\w\d]{6}", stringVariable)
.* for all digits atleast we found a composition of letters and words of 6 characters ([\w\d]{6})
Result:
Match 1: The.Test.Stsrisng.A01Y18
Match 2: The.Regex.F05P78
Match 3: Word.C05F78
