The "break;" breaks out of the while loop, causing it to skip the second 
check and all remaining records. You should be doing this in the SQL:

SELECT hUrl,hContactEmail FROM hyperlinks_data WHERE hUrl = 
"$websiteUrl" and hContactEmail = "$websiteEmail";

That's because you have only one = sign there.

= by itself does the assignment (setting a value)
== does comparison.

Sometimes, you do *both* an assignment and "test" the "answer" in a single
line like this:

if ($row = mysql_fetch_row($result)){

Here, the = does an "assignment" (sets the value) and then the *VALUE* is
tested to see if there is something there or not.

The = sign is only roughly similar to = in Mathematics.

Or, perhaps it would be better to say that:

= is like "Suppose x = 5.  Then..."
== is like "Is x = 5?"

[PHP] Re: Whats wrong with getimagesize ??

[andy]

hi.. foud the error. For everybody who might cope with the same error:

the prob was that getimagesize requires a path name without protocol like:
/pictures/12.gif

http://server.com/pictures/12.gif does not work with htaccess and imagesize

Thats it. easy hah :-)

Read this :

  Using Strings   :
  -
  http://www.zend.com/zend/tut/using-strings.php

Notice :

  echo "This will give a "parse error" to us";
  echo "This will not give a \"parse error\" to us";
  echo "This won't either";
  echo 'But 'this' will';
  echo 'But this won\'t';

Besides, one doesn't need quotes to echo a variable.

Regards,
Philip
