preg_split with regex giving incorrect output - php

I'm using preg_split to an string, but I'm not getting desired output. For example
$string = 'Tachycardia limit_from:1900-01-01 limit_to:2027-08-29 numresults:10 sort:publication-date direction:descending facet-on-toc-section-id:Case Reports';
$vals = preg_split("/(\w*\d?):/", $string, NULL, PREG_SPLIT_DELIM_CAPTURE);
is generating output
Array
(
[0] => Tachycardia
[1] => limit_from
[2] => 1900-01-01
[3] => limit_to
[4] => 2027-08-29
[5] => numresults
[6] => 10
[7] => sort
[8] => publication-date
[9] => direction
[10] => descending facet-on-toc-section-
[11] => id
[12] => Case Reports
)
Which is wrong, desire output it
Array
(
[0] => Tachycardia
[1] => limit_from
[2] => 1900-01-01
[3] => limit_to
[4] => 2027-08-29
[5] => numresults
[6] => 10
[7] => sort
[8] => publication-date
[9] => direction
[10] => descending
[11] => facet-on-toc-section-id
[12] => Case Reports
)
There something wrong with regex, but I'm not able to fix it.


I would use
$vals = preg_split("/(\S+):/", $string, NULL, PREG_SPLIT_DELIM_CAPTURE);
Output is exactly like you want


It's because the \w class does not include the character -, so i would expand the \w with that too:
/((?:\w|-)*\d?):/


Try this regex instead to include '-' or other characters in your splitting pattern: http://regexr.com?32qgs
((?:[\w\-])*\d?):

How to split 1 array into 2 arrays, remove certain items, and combine them again into 1 array in PHP?

i want to create something using array. I have 1 array and i need to split it into 2 array. After that search specific items from both array and remove it then combine it 2 array into 1 array.
How do i do that?
I already try to use unset for array but confuse how to use it for specific key since my array data format like 16/2/1/1 and 16/2/1/5. I need to remove data which have 1.
My format array is like this
Array
(
[1] => Array
(
[0] => 16/2/1/1 --> remove this have 1 after 2
[1] => 16/2/0/2
[2] => 16/2/0/3
[3] => 16/2/0/4
[4] => 16/2/0/5
[5] => 16/2/0/6
[6] => 16/2/0/7
[7] => 16/2/0/8
[8] => 16/2/0/9
[9] => 16/2/0/10
[10] => 16/2/0/11
[11] => 16/2/0/12
[12] => 16/2/0/13
[13] => 16/2/0/14
[14] => 16/2/0/15
[15] => 16/2/0/16
)
[2] => Array
(
[0] => 16/2/0/1
[1] => 16/2/0/2
[2] => 16/2/0/3
[3] => 16/2/0/4
[4] => 16/2/1/5 --> and this have 1 after 2 before 5
[5] => 16/2/0/6
[6] => 16/2/0/7
[7] => 16/2/0/8
[8] => 16/2/0/9
[9] => 16/2/0/10
[10] => 16/2/0/11
[11] => 16/2/0/12
[12] => 16/2/0/13
[13] => 16/2/0/14
[14] => 16/2/0/15
[15] => 16/2/0/16
)
)
i expect the output something like (after combine)
Array
(
[0] => 16/2/0/2
[1] => 16/2/0/3
[2] => 16/2/0/4
[3] => 16/2/0/6
[4] => 16/2/0/7
[5] => 16/2/0/8
[6] => 16/2/0/9
[7] => 16/2/0/10
[8] => 16/2/0/11
[9] => 16/2/0/12
[10] => 16/2/0/13
[11] => 16/2/0/14
[12] => 16/2/0/15
[13] => 16/2/0/16
)
Thanks for time to help me.

Make the array unique and then extract items that are digits/digits/NOT 1/digits:
$array = preg_grep('#^\d+/\d+/[^1]/\d+#', array_unique($array));

I would use preg_grep which allows you to search an array using a Regular expression.
$array =[
'16/2/0/13',
'16/2/0/16',
'16/2/1/5'
];
$array = preg_grep('~^16/2/0/\d+$~', $array);
print_r($array);
Output
Array
(
[0] => 16/2/0/13
[1] => 16/2/0/16
)
Sandbox
The Regex
^ match start of string
16/2/0/ - match literally (at the start of string, see above)
\d+ any digit one or more
$ match end of string
So Regular expressions is a way to do pattern matching, in this case the pattern is 16/2/0/{n} where {n} is any number. So by doing this we can find only those items that match that pattern.
Then if you have duplicates, you can do array_unique() and easily remove those.
There are many ways to do this array_filter with a custom callback etc. But this is the most straightforward way (if you know Regex).

The first element of your array is blank because your string begins with *. To solve this simply do:

You could pass it to array_filter to remove first child (index 0). It happen because you have * on first part of string. Exploding by * delimiter mean zero string on first value.
Something like:
$array = explode("*",$str);
$array = array_filter($array);

This is occurring simply because you have a "*" character at the start of the string
*HQ,6170929875,V1,185905,A,3127.3354,N,07307.6954,E,000.09,000,060718,FFFFB9FF,410,04,03104,32566#*....
If you always have that character at the start of the string, you will always have an empty index 0 in your resultant array - you need to either remove the first character before exploding the string or the first item of the array.

You might use a combination of array_filter to remove the empty values and array_values to reindex the array to start from 0:
$str = "*HQ,6170929875,V1,185905,A,3127.3354,N,07307.6954,E,000.09,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,185915,A,3127.3365,N,07307.6951,E,002.30,018,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,185925,A,3127.3372,N,07307.6952,E,000.76,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,185935,A,3127.3369,N,07307.6947,E,000.27,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,185945,A,3127.3371,N,07307.6951,E,000.27,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,185955,A,3127.3377,N,07307.6952,E,000.21,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,190005,A,3127.3376,N,07307.6950,E,000.17,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,190015,A,3127.3376,N,07307.6953,E,000.07,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,190025,A,3127.3375,N,07307.6955,E,000.59,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,190035,A,3127.3373,N,07307.6944,E,000.35,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,190045,A,3127.3378,N,07307.6950,E,000.23,000,060718,FFFFB9FF,410,04,03104,32566#*HQ,6170929875,V1,190055,A,3127.3381,N,07307.6955,E,000.32,000,060718,FFFFB9FF,410,04,03104,32566#";

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;

How to stop splitting within a pair of second delimiter in preg_split (PHP)?

I need to generate an array with preg_split, as implode('', $array) can re-generate the original string. `preg_split of
$str = 'this is a test "some quotations is her" and more';
$array = preg_split('/( |".*?")/', $str, -1, PREG_SPLIT_DELIM_CAPTURE);
generates an array of
Array
(
[0] => this
[1] =>
[2] => is
[3] =>
[4] => a
[5] =>
[6] => test
[7] =>
[8] =>
[9] => "some quotations is here"
[10] =>
[11] =>
[12] => and
[13] =>
[14] => more
)
I need to take care of the space before/after the quotation marks too, to generate an array with the exact pattern of the original string.
For example, if the string is test "some quotations is here"and, the array should be
Array
(
[0] => test
[1] =>
[2] => "some quotations is here"
[3] => and
)
Note: The edit has been made based on initial discussion with #mikel.

Will this work for you ?
preg_split('/( ?".*?" ?| )/', $str, -1, PREG_SPLIT_DELIM_CAPTURE);

This should do the trick
$str = 'this is a test "some quotations is her" and more';
$result = preg_split('/(?:("[^"]+")|\b)/', $str, -1, PREG_SPLIT_DELIM_CAPTURE);
$result = array_slice($result, 1,-1);
Output
Array
(
[0] => this
[1] =>
[2] => is
[3] =>
[4] => a
[5] =>
[6] => test
[7] =>
[8] => "some quotations is her"
[9] =>
[10] => and
[11] =>
[12] => more
)
Reconstruction
implode('', $result);
// => this is a test "some quotations is her" and more

escaping user input while keeping smarty variables

I have an array of sample user string inputs which may or may not have smarty variables in them which id like to escape with {literal}{/literal} tags.
Array
(
[0] => {$PLEASE}
[1] => {PLEASE}
[2] => {{PLEASE}}
[3] => {{{PLEASE}}}
[4] => {a{PLEASE}}
[5] => {a{$PLEASE}}
[6] => {{$PLEASE}a}
[7] => {{PLEASE}a}
[8] => {{{$PLEASE}}}
[9] => {{{{PLEASE}}}}
)
Here is what I hope to achieve.
Array
(
[0] => {$PLEASE}
[1] => {literal}{PLEASE}{/literal}
[2] => {literal}{{PLEASE}}{/literal}
[3] => {literal}{{{PLEASE}}}{/literal}
[4] => {literal}{a{PLEASE}{/literal}
[5] => {literal}{a{/literal}{$PLEASE}{literal}}{/literal}
[6] => {literal}{{/literal}{$PLEASE}{literal}a}{/literal}
[7] => {literal}{PLEASE}a}{/literal}
[8] => {literal}{{{/literal}{$PLEASE}{literal}}}{/literal}
[9] => {literal}{{{{PLEASE}}}}{/literal}
)
Right now I have this
$data = preg_replace('/{+([^\$])([a-z0-9]*)}+/si', '{literal}{\1\2}{/literal}', $data);
Which gives me
Array
(
[0] => {$PLEASE}
[1] => {literal}{PLEASE}{/literal}
[2] => {literal}{PLEASE}{/literal}
[3] => {literal}{PLEASE}{/literal}
[4] => {a{literal}{PLEASE}{/literal}
[5] => {a{$PLEASE}}
[6] => {{$PLEASE}a}
[7] => {literal}{PLEASE}{/literal}a}
[8] => {{{$PLEASE}}}
[9] => {literal}{PLEASE}{/literal}
)
Been stuck for quite sometime now, was wondering if anyone could help me figure it out or if its even possible to do so.

ok, I'm sure there's a more elegant way, perhaps one-liner, but whatever, it works with the following:
//Step 1: Replace 'real' smarty variables with an intermediate string
$data1 = preg_replace('/{(\$\w+)}/', "!!!$1!!!", $arr);
//replace start and end curly braces with {literal}:
$data2 = preg_replace('/{(.*)}/', '{literal}{$1}{/literal}', $data);
//Replace all inner smarty variables with their original string:
$data3 = preg_replace('/.!!!(.*)!!!/', '{/literal}$1{literal}', $data2);
//Replace standalone variables with their original string:
