[SOLVED] Help with empty() and is_null()

[wtfsmd]

How would i get this to work?

I don't get any syntax errors it just doesn't want to work.

 

<?php
if ( !empty($icq) || !is_null($icq) ) {
  echo "this";
}
?>

Where do you define (or not) $icq ?

[wtfsmd]

What do you mean?

I just want to know if it is not empty or is not null

[jlhaslip]

Is the variable used in a Form or might it be coming from a DB query? Where is it coming from if it is not null or not empty? is oit an array? Does it simply appear out of thin air?

Sorry i read that wrong

It comes out of my MySQl db

 

<?php

$query = "SELECT * FROM user WHERE id='$id'";
$result = mysql_query($query) or die(mysql_error());
$row = mysql_fetch_array($result) or die(mysql_error());

$icq = $row['icq'];
if ( !empty($icq) || !is_null($icq) ) {
  echo "this";
}
?>

do you mean this statement.

 

<?php

$a['name']==" ";
$a['name']=NULL;


if(empty($a['name'])&& is_null($a['name'])){

echo hi;
}
?>

do you mean this statement.

 

<?php

$a['name']==" ";
$a['name']=NULL;


if(empty($a['name'])&& is_null($a['name'])){

echo hi;
}
?>

 

no not like that, it comes out of my database. I want to know this "if $icq is not empty OR is not null"

which is what my statement says.

Your original code works as expected. Obviously $icq isn't what YOU think it is however.

On top of that, empty returns true when its argument is NULL, so theres really no need to check for both.

I removed the " || !is_null ($icq) " from the statement and it works as expected. When i look at the row in my DB its empty

 

As for the new post i am dumb for not even realizing that empty returns true for null, and that works just fine thanks.
