Get string between two strings
(6 answers)
Closed 6 years ago.
I'm trying to get the string between two specific matches, for example two hashtags.
What I would like to achieve:
input: some text in front ##hi there## some text behind
output: hi there
With /%%(.*)%%/, ##hi there## is returned.
Thanks in advance
You need a look ahead and look behind.
(?<=##).*(?=##)
This will match hi there

I am trying to add the int with strings in PHP but I could get a helpful answer on StackOverflow and other website communities.
I want the code separate the ALPHABETS and NUMBER and then add the value in NUMBER and again JOIN the ALPHABETS AND ADDED NUMBER together.
How I achieve this, Please help.
Example:
$mynumber = 'SBI0001';
$addValue = '1';
It will be 'SBI0002' in PHP.

how can i do the operation for obtaning the total result?
Thank You
Maybe your question is a possible duplicate from calculate-math-expression-from-a-string-using-eval
However
if you need to store this in a variable you can do
$string='((((((4,50*0,86)*52500*1,0016)+3800)/52500)*2,2046)*1,05)';
$response=eval('return '.str_replace(',','.',$string.';'));
print($response);
the output is:
9.14027512736

i haves string such as
andy
**jackie**
rudy
linda
ferry
**jackie**
linda
rudy
ammy
**jackie**
tortia
Is it possible to have it removed everything and get the result only below
**jackie**
tortia
it should be possible with substr
thanks
Yes, you can use substr.
But at first you have to find third occurence of jackie. Maybe this function will be helpful https://stackoverflow.com/a/18589825/2701717
