Question

示例

$string = "Test Line 1 
Test Line 2 
Test Line 3"; 
echo str_replace(PHP_EOL,"/".PHP_EOL, $string );

实际上我期待输出是

测试线1 \

测试线2 \

测试线3 \

请帮我解决这个问题

Answer 1

使用\\代替"/"

<?php
$string = "Test Line 1 
Test Line 2 
Test Line 3"; 
 $var=str_replace(PHP_EOL,"\\"."</br>", $string ); 
echo $var." \\"; // this append \ in last string
?>

Answer 2

试试这个，

<?php
    $string = "Test Line 1 
    Test Line 2 
    Test Line 3"; 
    $str = str_replace(PHP_EOL,"\<br />", $string) . " \\"; 
    echo $str;
?>

Answer 3

如果只是为了让你可以将php值放入JS变量中，你可以使用json_encode()，这会将新行改为\n

$string = "Test Line 1 
Test Line 2 
Test Line 3"; 

echo json_encode($string);
// outputs(including quotes) "Test Line 1 \nTest Line 2 \nTest Line 3"

如何在php的每一行添加符号？
