[PHP] Array query - finding the key for a value

[Tim Fountain]

This may be a silly question, but I'm used to being able to find PHP
functions to do whatever I want, but I can't find one to do this!

If I have an array like this:

[0] - 'apple';
[1] - 'pear';
[2] - 'orange';
[3] - 'apricot';

I know I can use in_array() to check whether, say, 'orange' is in the
array; but how do I then find out which index 'orange' is at?

 for example:

 preg_match('/test/', ...) should return me somehow: 10

 How about this:

 $mem='this is a test';

 if(preg_match(/(.*)test/,$mem,$matches)) {
   echo strlen($matches[1]);
 }

 Of course, if test occurs more than once then the above won't
 work, since regex's are greedy...

If you add a ? after the * then that'll make it non-greedy won't it?

Re: [PHP] Using PHP with MySQL - Can I supress MySQL errors?

 I'd like to suppress these messages as I am storing the error,
 mysql_error(), in an array. So if there is an error, I would simply
 display the contents of the array in a nice format.

Assuming I understand you correctly, to surpress errors from PHP
functions simply put an '@' symbol before the function.  This will
surpress the error message from PHP but will still execute your 'or'
statement, storing the message in your array, e.g.:

$result = @mysql_connect('blah','blah','blah') or
some_error_function();

or I guess you could also do:

$result = @mysql_connect('blah','blah','blah');
if (!$result)
{
   $error_array[] = mysql_error();
   ...
}
