I need that the single quotation mark, will be a double one, and not in html code.

$new_str = str_replace('\'', '"', $web);
You could optional do it by modifying the actual string (note the use of \to escape the quotation marks):
您可以通过修改实际字符串来选择执行此操作（请注意使用\来转义引号）：
$web = "...if (url.contains(\".mp4\"))..."

Short of doing a strtr()replacement, just escape your double quotes:
没有做strtr()替换，只需转义双引号：
$web = "...if (url.contains(\".mp4\"))..."
See http://www.php.net/manual/en/language.types.string.php#language.types.string.syntax.doublefor the complete list of escaping rules.
有关转义规则的完整列表，请参阅http://www.php.net/manual/en/language.types.string.php#language.types.string.syntax.double。
