Question

我有类似波纹管的文字，我需要在逗号和'（单引号）之后或此符号'（单引号）之前和之后删除空格

$text = "'game', ' open world', ' test rpg'"

预期结果

$text = "'game','open world','test rpg'"

我已经尝试过这个波纹管，但要删除每个空格

$tested = preg_replace('/\s+/', '', $text);

Answer 1

echo preg_replace('/\s+?\'\s+?/', '\'', $text);

Answer 2

尝试这个：

<?php
$text = "'game', ' open world', ' test rpg'";
$str = explode(",",$text);
$arr = array();
foreach ($str as $key) {
    array_push($arr, trim($key));
}

print_r(implode(',',$arr));
?>

查看这些php函数implode和explode

Answer 3

选项1：

$text  = explode("', ' ",$text);
$text = implode("','",$text);

选项2：

$text = str_replace("', ' ","','",$text)

代码：

$text = "'game', ' open world', ' test rpg'";

echo preg_replace('/(\s?\'\s?)/', "'", $text);

implode

Answer 6

以前的正则表达式答案不考虑逗号之后（而不是id=之前）的空格，例如'。这是一个适用于逗号和空格的解决方案：

open, world

删除逗号和“或此符号前后”的空格
