Question

如何在空格后添加换行符？

<?php

$trxinfo = "R# VGG20.085760253978 SUCCESS. SN/Ref: 6131718556/CODE=QV5TP-U9U8W-BGUPM-65N53-D8Y52. Price 18,800. Amount 1,943,778 - 18,800 = 1,924,978. Date 04/10 10:36:15";

$myArray = preg_split('/[\s.]+/', $trxinfo);
print_r($myArray);

?>

输出结果为：

Array ( [0] => R# [1] => VGG20 [2] => 085760253978 [3] => SUCCESS [4] => SN/Ref: [5] => 6131718556/CODE=QV5TP-U9U8W-BGUPM-65N53-D8Y52 [6] => Price [7] => 18,800 [8] => Amount [9] => 1,943,778 [10] => - [11] => 18,800 [12] => = [13] => 1,924,978 [14] => Date [15] => 04/10 [16] => 10:36:15 )

我该怎么办？添加\n

Answer 1

如果您不介意，在这种情况下您也可以使用explode()。例如：

$trxinfo = "R# VGG20.085760253978 SUCCESS. SN/Ref: 6131718556/CODE=QV5TP-U9U8W-BGUPM-65N53-D8Y52. Price 18,800. Amount 1,943,778 - 18,800 = 1,924,978. Date 04/10 10:36:15";
$myArray = implode("\n", explode('. ', $trxinfo));
echo nl2br($myArray);

应该是这样的：

R# VGG20.085760253978 SUCCESS
SN/Ref: 6131718556/CODE=QV5TP-U9U8W-BGUPM-65N53-D8Y52
Price 18,800
Amount 1,943,778 - 18,800 = 1,924,978
Date 04/10 10:36:15

代码

<?php
    $string = "R# VGG20.085760253978 SUCCESS. SN/Ref: 6131718556/CODE=QV5TP-U9U8W-BGUPM-65N53-D8Y52. Price 18,800. Amount 1,943,778 - 18,800 = 1,924,978. Date 04/10 10:36:15";

    $myArray = preg_split('/[\s\n]+/', $string, -1, PREG_SPLIT_DELIM_CAPTURE);
    $myArray = array_map('ltrim', $myArray);

    echo '<pre>'.print_r($myArray, true);  
?>

结果

Array
(
    [0] => R#
    [1] => VGG20.085760253978
    [2] => SUCCESS.
    [3] => SN/Ref:
    [4] => 6131718556/CODE=QV5TP-U9U8W-BGUPM-65N53-D8Y52.
    [5] => Price
    [6] => 18,800.
    [7] => Amount
    [8] => 1,943,778
    [9] => -
    [10] => 18,800
    [11] => =
    [12] => 1,924,978.
    [13] => Date
    [14] => 04/10
    [15] => 10:36:15
)
