Question

可能重复：
  quick function to replace ' with \' in php
  Is there a PHP function that only adds slashes to double quotes NOT single quotes

我有例如：

$one = 'put "returns" between "paragraphs"';

$two = '"linebreak" add 2 spaces "at end"';

如何将其转换为：

$one = 'put \"returns\" between \"paragraphs\"';

$two = '\"linebreak\" add 2 spaces \"at end\"';

Answer 1

要添加斜杠，请使用

$one = addslashes($one);

或删除

$one = stripslashes($one);

Answer 2

$one = str_replace('"', '\"', $one);

Answer 3

您正在寻找的功能是str_replace或addcslashes：

$one = 'put "returns" between "paragraphs"';

$slashed = addcslashes($one, '"');

echo $slashed;
