Backslash before forward slash..

[Adam]

Is there a predefined function in PHP for adding backslashes in front of forward slashes? Some kind of regular expression escape function? ... Rather than:

 

str_replace('/', '\/', $str);

 

.. not the prettiest of code! I've done some Googlin' but can't seem to find anything!

 

Thanks,

Adam

str_replace('/', '\/', $str);

This is faster than any regular expression operation.

addcslashes() allows you to identify which characters you want to escape with a \

Oh no I don't want to use a regular expression to do it, I want to escape a variable for use in a regular expression, if you catch my drift? Like mysql_real_escape_string, but for regular expressions.. But more specifically to convert '/' to '\/'.. I was just wondering really if there was a predefined function for this.

 

I have to get off now but I'll take a look into addcslashes() later on..

 

Cheers!

No, there is no predefined function for this however

 

$str = addcslashes($str, '/');

is probably no more efficient than

$str = str_replace('/', '\/', $str);

 

They both perform the same operation
