Andrey, you are incorrect.

From the manual on strpos():
int strpos (string haystack, string needle [, int offset])
If needle is not found, returns FALSE.

From the docs :
Note: It is easy to mistake the return values for character found at position 0 and 
character not found.  Here's how to detect
the difference:

// in PHP 4.0b3 and newer:
$pos = strpos($mystring, b);
if ($pos === false) { // note: three equal signs
// not found...
}

// in versions older than 4.0b3:
$pos = strpos($mystring, b);
if (!is_integer($pos)) {
// not found...
}

RE: [PHP] comparisons

2001-02-12 Thread PHPBeginner.com 

try this first:

if((strlen($pick1)==strlen(pick2))and($pick1==$pick2))
echo 'they are equal';
else
echo 'they aren\'t at least in length';

However, it seens to me as a very slicky style ...  whay not to make them
somehow different   let's say using an array, or having a letter instead
of 0 ...

Subject: [PHP] comparisons


Hello,
  I'm having a rather strange problem.  I'm trying to compare two values.
"01" and "1".  The variables names that they are submitted under are pick1
and pick2.   i use the following code

$mypick1 = strval($pick1);
$mypick2 = strval($pick2);

I then perform the following comparison:

if ($mypick1 == $mypick2)
 {
   $error = 1;
   $errorstring[1] = "Your first pick and second pick are the same.";
 }

However, I get the error that they are equal.

If I call the comparison as foloows:

if(strval($mypick1) == strval($mypick2)
 {
   $error = 1;
   $errorstring[1] = "Your first pick and second pick are the same.";
 }

I still get the error.  Anyone have any ideas?  These two valuse mustbe
evaluated as different.

Thanks in advance
Curtis

2001-02-11 Thread Phil Driscoll 

In spite of yor best efforts here, PHP converts the string values to numbers (because 
the strings look like numbers) before doing the comparison.

Force a string comparison by using strcmp and everything will work fine - remember 
that strcmp returns true if the strings are not equal and false if equal.

2001-02-11 Thread Curtis Maurand 

That was the solution.  It worked like a charm.

$cmpresult = strcmp($pick1,$pick2);
 if $cmpresult == 0)
  {
my code;
  }

Can I also write that like the following?

if (strcmp($pick1,$pick2) == 0)
 {
   perform some action;
 }

Will that work?
