Question

我试着在谷歌找到答案，但没有运气！

为什么当我尝试爆炸字符串时它不起作用？

$Text = "brazil,banks,home,,uk,,,,test,financial times,.,ipad,,banks,,Two words,,";

$Text_Array = explode(",",$Text);

$Text_Array = array_filter($Text_Array);

print_r($Text_Array);

我希望将所有标记除以一个逗号并删除任何空格和重复标记。

我想要这个结果：

“巴西，银行，家庭，英国，考试，金融时报，ipad，两个字”;

拜托，你能帮助我实现这个目标吗？

Answer 1

如果您想remove any space and duplicate tags，则还需要array_unique添加array_filter

$textAray = array_unique(array_filter($textAray));

注意 ..请注意，这不会删除结果中的. ..这是过滤结果的更好方法

$text = "brazil,banks,home,,uk,,,,test,financial times,.,ipad,,banks,,Two words,,";
$textArray = array_unique(preg_split("/[,.]+/", $text));
$textArray = array_filter($textArray);
echo implode(",", $textArray);

输出

brazil,banks,home,uk,test,financial times,ipad,Two words

Answer 2

你需要的是array_unique函数：

$Text_Array = array_unique($Text_Array);

所以你的代码变成了：

$Text = "brazil,banks,home,,uk,,,,test,financial times,.,ipad,,banks,,Two words,,";

$Text_Array = explode(",",$Text);

$Text_Array = array_filter($Text_Array);

$Text_Array = array_unique($Text_Array);\

print_r($Text_Array);

然后您将获得所需的输出。

Answer 3

在爆炸字符串

之前，您可以用一个逗号替换多个连续逗号

$Text = "brazil,banks,home,,uk,,,,test,financial times,.,ipad,,banks,,Two words,,";

$Text = preg_replace("/,+/", ",", $Text);
$Text_Array = explode(",",$Text);

print_r($Text_Array);

请注意，您的数组中仍然会有一个包含点的元素，如果您的字符串以逗号结尾，则该数组的最后一个元素将为空。

Answer 4

你需要这样的代码

$Text = "brazil,banks,home,,uk,,,,test,financial times,.,ipad,,banks,,Two words,,";

$str = substr(preg_replace('/(.+?)[,]+/', '$1,', $Text),0,strlen($str)-1);
$arr = array_unique(explode(',', $str));
print_r($arr);

你需要用一个替换，或者更多，我已经用preg_replace
从字符串中删除最后一个
爆炸，
通过array_unique（）

Answer 5

试试这个：

<?php
$Text = "brazil,banks,home,,uk,,,,test,financial times,.,ipad,,banks,,Two words,,";
$Text = str_replace('.','',implode(',',array_unique(explode(',', $Text))));
$Text_Array = explode(",",$Text);

$Text_Array = array_filter($Text_Array);

print_r($Text_Array);
?>

Answer 6

您可以删除示例中所有不必要的逗号，方法是将“,,”替换为“，”，直到不存在“,,”为止。

while ( strstr($Text,',,') !== false ) {
    $Text = str_replace($Text,',,',',');
}

使用过的功能：

Answer 7

除了这些人提供的解决方案之外，您可以尝试按照您的意愿打印值： -

foreach($Text_Array as $textval)
{
echo $textval . ",";
}

Answer 8

你可以试试这个

<?php

$Text = "brazil,banks,home,,uk,,,,test,financial times,.,ipad,,banks,,Two words,,";

$Text=str_replace(array(",,",",,,,",",.,",",,"),',',$Text);

$Text_Array = explode(",",$Text);

$Text_Array = array_filter($Text_Array);

print_r($Text_Array);
//output :: Array ( [0] => brazil [1] => banks [2] => home [3] => uk [4] => test [5] => financial times [6] => ipad [7] => banks [8] => Two words )
?>

爆炸不适用于字符串中的多个逗号
