I have this code:
for($i=1; $i<=6; $i++)
{
echo "<br>picture.$i._name";
}
The output of this is:
picture.1._name
picture.2._name
picture.3._name
picture.4._name
picture.5._name
picture.6._name
How can I get it to print this instead:
picture1_name
picture2_name
picture3_name
picture4_name
picture5_name
picture6_name

Either
for($i=1; $i<=6; $i++)
{
echo "<br>picture${i}_name";
}
or
for($i=1; $i<=6; $i++)
{
echo "<br>picture{$i}_name";
}
or
for($i=1; $i<=6; $i++)
{
echo "<br>picture" . $i . "_name";
}
All should do the job. For reference, read the section about simple and complex syntax for variable parsing at http://www.php.net/manual/en/language.types.string.php#language.types.string.parsing

for($i=1; $i<=6; $i++)
{
echo "<br>picture".$i."_name";
}

Can you tell me why this isn't working:
for($i=1; $i<=6; $i++)
{
if($this->picture".$i."_name == "")
continue;
}
Only get parse error in the if-test :mad:

not enough info to go on there :)
is that code part of a class function ? where is $this coming from ?
the concat is wrong i.e. it should be
$this->picture.$i."_name";
but if you are saying that there is an object variable called eg
$this->picture1_name
then you may have to do something similar to.
for($i=1; $i<=6; $i++)
{
$temp=$this->picture.$i."_name";
echo ${$temp};
}
but without knowing what $this is is hard to say

i want to test if the objects $picture1_name is empty...
got a solution to it:
if($this->{"picture".$i."_name"} == "")
continue;
thanx anyway :)
