i want to call a function which is defined outside the loop but called inside the loop and then access a variable from that function definition which is outside the loop to inside the loop every time loop runs
here is the database connectivity that contains while loop and a funtion calling and then accessing the $second_trim variable defined in ""function page($h)"" inside the while loop
<html>
<head>
<title></title>
</head>
<body>
<?php
$getquery = mysql_query("SELECT * FROM table WHERE $construct LIMIT $start, $per_page");
while($runrows = mysql_fetch_assoc($getquery))
{
$title = $runrows ['Title'];
$url = $runrows ['URL'];
page($url);
echo "<div style='clear: both;position:relative;border:1px solid #A5BEBE;background-color: white;'>
$second_trim</div>";
}
function page($h){
$i=fopen($h,"r");
$contents=stream_get_contents($i);
fclose($i);
$contents=strtolower($contents);
$start='<div';
$start_pos=strpos($contents,$start);
$first_trim=substr($contents,$start_pos);
$stop='</div>';
$stop_pos=strpos($first_trim,$stop);
$second_trim=substr($first_trim,0,$stop_pos);
}
?>
</body>
</html>
the while loop fetch url from the database and pass through "page($url)" function called inside the loop to defined function "function page($h)"outside the loop it will get required content in $second_trim that will displayed inside the loop in echo statement every time it runs but i m getting the error like Fatal error: Call to undefined function crawl_page() their is some syntax problem i m facing that i cant find after alot of search is their any can do this plz help me out
You need to define your function -> function page($h){...} before your loop. Second, return the $second_trim at the end of your function, and third set your function call to your variable
...your html...
<?php
function page($h){
$i=fopen($h,"r");
$contents=stream_get_contents($i);
fclose($i);
$contents=strtolower($contents);
$start='<div';
$start_pos=strpos($contents,$start);
$first_trim=substr($contents,$start_pos);
$stop='</div>';
$stop_pos=strpos($first_trim,$stop);
$second_trim=substr($first_trim,0,$stop_pos);
//return the value
return $second_trim;
}
$getquery = mysql_query("SELECT * FROM table WHERE $construct LIMIT $start, $per_page");
while($runrows = mysql_fetch_assoc($getquery)){
$title = $runrows ['Title'];
$url = $runrows ['URL'];
//save the function returned value to variable
$second_trim = page($url);
echo "<div style='clear: both;position:relative;border:1px solid #A5BEBE;background-color: white;'>
$second_trim</div>";
}
?>
...your html...
