I need some help, and I don't know where else to turn. 3 years ago, there were a handful of PHP coding forums that offered plenty of help. But for whatever reason (PHP is out of favor and so are forums?), they aren't active anymore.
So the error I'm getting is "Fatal error: Can't use function return value in write context in /Users/lholcombe/Sites/triple-bypass/process3.php on line 84". Which I'm sure is related to the function reference variables I am passing. I didn't want to use things like reference variables specifically because I knew it would fuck things up. But I didn't know how else to get the effect I wanted.
Any assistance would be greatly appreciated.
The line in question is:
if (count($input1) = 1) {
And here's the whole code, for context (the line above is found in function_buildform3):
<?php
$prefix1 = $_POST['prefix1'];
$name1 = $_POST['name1'];
$type1 = $_POST['type1'];
$suffix1 = $_POST['suffix1'];
$prefix2 = $_POST['prefix2'];
$name2 = $_POST['name2'];
$type2 = $_POST['type2'];
$suffix2 = $_POST['suffix2'];
$success = 1;
$output = 1;
street_process($prefix1,$name1,$type1,$suffix1,1,$success,$output);
if ($success == 0) {
not_found(1);
}
else {
$output1=$ouput;
}
$success = 1;
$output = 1;
street_process($prefix2,$name2,$type2,$suffix2,2,$success,$output);
if ($success == 0) {
not_found(2);
}
else {
$output2=$ouput;
}
build_form3($output1,$output2);
// End main function
// function street_process
function street_process($prefix,$name,$type,$suffix,$iteration,&$success,&$output)
{
$name = strtoupper($name);
$conn_string = "host=localhost port=5432 dbname=testKCstreets user=postgres password=*******";
$db = pg_connect($conn_string);

}
if (is_null($result_list[0])) {
return $success = 0;
}
else {

sort($output);
return;

}

echo $input1[0];
}
else {

for ($i=0; $i<count($input1); $i++){
echo "<input type=\"radio\" name=\"street1", $i, "\" value=\"", $input1[$i], "\">";
echo $input1[$i];
echo "<br>";
}
}
echo "<br><br>";
if (count($input2) = 1) {

echo $input2[0];
}
else {

exit;
}
?>
For the record, I'm 100% self taught in PHP. I did some modifications in phpBB a few years ago, but this is my first time trying to build something from the ground up. Pretty much everything I know comes from the PHP.net documentation, which I found last week.
