Wy in Php 01 is greater than 1 ?
6  1502 
At Sat, 12 May 2007 06:28:04 -0700, wbrowse let his monkeys type:
Wy in Php 01 is greater than 1 ?
It's not, not even when comparing these as strings.
echo (01 1) ? 'bigger' : 'equal or smaller';
// outputs: equal or smaller
echo ('01' '1') ? 'bigger' : 'equal or smaller';
// outputs: equal or smaller
Show the code you used to get the result you did if you want more help...

It isn't. But perhaps you meant something else?
Maybe he mean '01' is bigger than ' 1'. It would be.

But even then:
$ php -r "var_dump(' 01' ' 1');"
bool(false)
$ php -r "var_dump(' 01' < ' 1');"
bool(false)
You have to get down to strcmp() to start showing up a difference, which
strays even further from what the OP posted.
$ cat test.php
<?php
$a = array('01', ' 1', '1');
sort($a);
print join("\n", $a);
?>
$ php test.php
1
1
01
So, back to the OP to clarify what he's on about... but certainly the sort
results above are a reasonable cause for confusion unless you get your head
around exactly when PHP does implicit type conversions.

Of course you're right... I should think more before replying... :-)

First, sorry for telling you so little with this issue and leaving it
for so long without much care from me...
Below you can find the script that made feel confused (I am an early
Php beginner but I have to stop as for professional needs I need to
concentrate my free time on learning VBA...) :
Test it with 01 as I can't test it on my current configuration(s ee
below why).
===========star t==========
<html>
<head>
</head>
<body>
<?php
//lancer recherche $_POST['submit'] dans fichier aide PHP
if (!$_POST['submit'])
{
?>
<form action="<?=$_SE RVER['PHP_SELF']?>" method="post">
Saisissez un nombre : <input name="nombre" size="2">
<input type="submit" name="submit" value="Valider" >
</form>
<?php
}
else
{
$nombre = $_POST['nombre'];
if ($nombre < 0)
{echo 'Vous avez saissi un nombre -';
}
elseif ($nombre 0)
{echo 'Vous avez saissi +';
}
else
{echo 'Vous avez saissi un nombre neutre';
}
}
?>
</body>
</html>
===========end= =========
As I changed computer, I had to reinstall php, apache and I wanted to
test this script again but I had this message:
You don't have permission to access /arch/< on this server.
The other script I run all are working (with forms...) under XP.
It's no big issue for me right now as it's confusing learning 2
languages at the same time... so I am concentrating on vba and leaving
Php for later...
