问题:

Hi I was wondering if there is an easy way to escape strings in php.

In python I use """ """, and everything between there is escaped. so when using special characters it is ignored.

I have some text to echo, and escaping everything manually just takes forever.

Does php have a similar function built in ?

thanks!

Which are the characters do you have to escape?

You could use single quotes ^[docs]. The only characters that have to be escaped in such a string are \ and '.

If you have a long string, also have a look at heredoc ^[docs].

Since PHP 5.3, you can use nowdoc. As opposed to heredoc, nowdoc does not expand variables inside it.

There are various functions depending on what you want to escape.

If you are using a lot of double quotes, for example with html, you can wrap the string in single quotes to prevent having to escape.

$string = '<a href="#">no escape needed</a>';

The same goes the other way

$string = "I'd rather be gaming";

Then you have a couple of functions used mostly for escaping user input:

addslashes() that will escape quotes
htmlspecialchars() will 'escape' html codes
mysql_real_escape_string() for escaping mysql input
