Re: [PHP] Check contents of variable

2001-11-20 Thread PHP List 

How about:

if (substr($url,0,7)  http://;)
$url = http://; . $url;


 Hi,

 which function would i use to check if a certain value is in the contents
of
 a variable?

 I have a form where the users submits url's. I need the url with http://
in
 the beginning. Since there is more data after the http:// i can´t just do
a
 simple if-statement. So what do i do?

 After i determined if there is a http:// in the variable or not i guess i
 just have to $url = http://; + $url; (?)...

 Regards

 if (substr($url,0,7)  http://;)
 $url = http://; . $url;

Thanks!

That´s just the function i am looking for. I looked it up in the manual.
Correct me if i am wrong - if i don´t set the second parameter in substr it
just continues to read until the variable is finished? If i set it to 7 (as
above) it stops reading after 7 characters?

Correct, the third parameter is for the number of characters to read,
nothing means entire string.

Function details can be found here:

You could also try:

if(! ereg('^http://', $url))
 $url = 'http://' . $url;
