how to turn texts to be array by line with PHP

aaaaaaaaaaaa
bbbbbbbbbbbbbb
ccccccccccccc开发者_如何学Ccccccc
dddddddddddddddddd

I want turn to be a array base on line like that

array(
0=>'aaaaaaaaaaaa',
1=>'bbbbbbbbbbbbbb',
2=>'ccccccccccccccccccc',
3=>'dddddddddddddddddd'

)

How to do it with php?

$string = "aaaaaaaaaaaa 
bbbbbbbbbbbbbb 
ccccccccccccccccccc 
dddddddddddddddddd";
$array = explode("\n", $string);

$arr = explode("\n", $str); // $str contains your text

The following is pretty flexible about line endings (newline or carriage return), or can be modified to include any space.

$lines = preg_split('/[\r\n]/', $text);

However, if you know the line ending to be \n (newline) I would recommend explode() as it avoids the regex overhead.

$lines = explode("\n", $text);

Read more on preg_split() and explode().

$myArray = explode($your_seperator_string, $string_to_be_parsed_to_array);

PHP's explode(string $delimiter , string $string [, int $limit ]) function splits a string by delimiter.

In PHP, new lines are represented by \n. Therefore, you can use explode() to create an array after each new line.

$string = "aaaaaaaaaaa
           bbbbbbbbb
           cccccccccccccccc
           ddddddddddd"

$string = "aaaaaaaaaaa\nbbbbbbbbb\ncccccccccccccccc\nddddddddddd"

//Both $string variables are the same

//Make sure that \n is in double quotes, single quotes WILL NOT WORK!!!
$array = explode("\n", $string);

There you go! Feel free to use array_map() and other similar functions with the \n to achieve the desired results.

Look into the split() method. PHP:split Manual

$myArray = split("[\n|\r]", $string);

Depending on the system that created the original string, you may or may not need the \r.

DEMO

<?php

  $sample = "aaaaaaaaaaaa
bbbbbbbbbbbbbb
ccccccccccccccccccc
dddddddddddddddddd";

$ary = array_map("trim",explode("\n", $sample));

var_dump($ary);

OUTPUT:

array(4) {
  [0]=>
  string(12) "aaaaaaaaaaaa"
  [1]=>
  string(14) "bbbbbbbbbbbbbb"
  [2]=>
  string(19) "ccccccccccccccccccc"
  [3]=>
  string(18) "dddddddddddddddddd"
}

I use trim in case they are either \r\n or \n separated. Can also use regex, but figure I'd offer one more solution and the array_map is optional.

$output_array = explode("\n<br />\n", $input_string);
