Hi,
i have a problem with a regular expression.
i want to split a string on character pipe | with preg_split php function.
The string is :
"foo|bar|'hello |world\'abc\'de f'|bye"
Result of split must be in an array :
foo
bar
hello|world'abc 'def
bye
Anyone have an idea ?
Thank you !!
bye

Are you controlling your deliminators or are they changing??
I wrote a code: - print_r(explode("||","foo||bar||'hello|world\'abc\'def'||bye"));
-
-
/* Outputs: */
-
Array
-
(
-
[0] => foo
-
[1] => bar
-
[2] => 'hello|world\'abc\'def'
-
[3] => bye
-
)
If you throw in a stripslashes: - print_r(explode("||",stripslashes("foo||bar||'hello|world\'abc\'def'||bye")));
-
-
/* Outputs: */
-
Array
-
(
-
[0] => foo
-
[1] => bar
-
[2] => 'hello|world'abc'def'
-
[3] => bye
-
)
You have not shown us how your data is fetched/made, all you said was how do you turn "foo|bar|'hello |world\'abc\'de f'|bye" into and array of: foo
bar
hello|world'abc 'def
bye I suggested that if you change your deliminator from | to || then you can use explode while keeping your hello|world together.
If you deliminator is changing, you did not mention that. If you find preg_split easier, go for your life. Generally explode and similar string functions are easier for debugging.
TheServant, you do not answer the question...
I know how to use the explode function, everyone knows how to use this function...
you say it is quicker and easier to convert input data, ok, I ask you to write the function that converts input data from "foo|bar|'hello |world\'abc\'de f'|bye" to "foo||bar||'hel lo|world\'abc\' def'||bye"
Regards,
I do not control the delimitator, otherwise, I never asked and I simplified input string...

You never said that you couldn't control the deliminator, and how am I meant to know your experience? In that case, using regex (or preg_split) is the way you should go. Glad it's solved.
@TheServant
I never said any more than I could change the string but it seems logical to me.
If I could change the string, do you really think I asked any questions ...

lets say I have a line of text with multiple spaces between each word..
I am not sure how many spaces. I would like to take the line of text,
and change it to put only one space between the words.
So, my idea was to split it on the spaces, then implode it with one
space between each word.
But, this doesn't work:
preg_split("/\\s*/","test test test test")

Why preg_split works only if the char # before the delimiter is 21 or less?

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
