Preg_Split() Multiple Delimiter ?

[natasha_thomas]

Friends,

 

I want to use Multiple delimiters to form an Arrar from a text.

 

delimiter i want to use are:

1- "." followed by a Space

2- "?" Followed by a Space

3- "." followed by a new Line "\n"

 

Code i am using is 

$arr = preg_split("/(\.\s+)/", $arr);

 

This only solving delimiter 1. how to achieve all the there Delimiters?

 

Thanks all

Ok Let me try...

 

Example:

Input text

This is test a. This is test b?

This is test c.

 

This Input should give three elements in Array:

This is test a.

This is test b?

This is test c.

 

Did i make it Clear?

 

What shall i put in preg_sllit() function to achieve this?

/[.?]\s+/

 

That will do what you want as well as a few other things like split on a ? followed by a newline and \s includes other whitespace like tab, formfeed and carriage return characters.

Thanks Salathe BUT....

 

Now am having strange problem....

 

Sample Text: How are you?

is coming like: How are you?. (Observe the "." after the question mark)

Top of it: The Newline is also not being treated as Delimiter, which i want.

 

I am sure this is happening because of

$arr = preg_split("/[.?]\s+/", $arr);

 

//$arr = file ( $file );

$total_lines = count( $arr );

 

$max_lines = min( $max_lines, $total_lines);

 

$r = range(1, $total_lines);

shuffle($r);

 

for( $a=1; $a <= $max_lines ; $a++ )

$arr_random[] = $arr[ $r[$a-1]-1 ];

 

$shuffled = join( ". ", $arr_random) . ".";

.

 

 

may you tell, what changes we need in this Code?

@natasha_thomas: Try giving us a complete sample, at least a paragraph or so, along with what you'd expect it to be separated out to (just list east part on a separate line.

 

 

Example:

Input:

The quick brown fox jumps over the lazy dog? The quick brown fox jumps over the lazy dog. The quick brown fox jumps

over the lazy dog.

 

 

Result:

The quick brown fox jumps over the lazy dog?

The quick brown fox jumps over the lazy dog.

The quick brown fox jumps

over the lazy dog.

[natasha_thomas]

Input:

The quick brown fox jumps over the lazy dog? The quick brown fox jumps over the lazy dog. The quick brown fox jumps

over the lazy dog.

 

 

Result:

The quick brown fox jumps over the lazy dog?

The quick brown fox jumps over the lazy dog.

The quick brown fox jumps

over the lazy dog.

 

Is what am looking for.  What should be changed in my Existing code that i can achieve it?

 

My Existing Code:

 

<?php

 

$file = $_GET['file'];

$max_lines = $_GET['lines'] ;

 

$shuffled_para = get_random_lines( $file, $max_lines );

 

echo $shuffled_para;

 

function get_random_lines( $file, $max_lines )

{

$arr = file_get_contents ( $file );

$arr = trim(trim($arr), ".");

$arr = preg_split("/\.\s+/", $arr);

//$arr = file ( $file );

$total_lines = count( $arr );

 

$max_lines = min( $max_lines, $total_lines);

 

$r = range(1, $total_lines);

shuffle($r);

 

for( $a=1; $a <= $max_lines ; $a++ )

$arr_random[] = $arr[ $r[$a-1]-1 ];

 

$shuffled = join( ". ", $arr_random) . ".";

 

return $shuffled;

}
