here is my function.when i click on the readp button,it will show undefined variable,but still can show out the string in txt file.
<?php
if(isset($_GET['readp'])){
readinfo($fname,$lname,$phone,$email,$mname,$gender,$city,$country,$fax,$exp);
}
?>
<?php
function readinfo($fname,$lname,$phone,$email,$mname,$gender,$city,$country,$fax,$exp){
$info=file('log.txt');
for($i=count($info)-1;$i>=0;--$i){
echo cleanOutputData($info[$i])."<br>";
}
}
?>
Where are you setting your $fname, $lname, $phone etc... variables?
$info= fopen("log.txt", "a+");
$newinfo=$fname . "---". $mname . "---".$lname . "---".$gender. "---".$city. "---".$country."---". $phone . "---".$fax."---". $email."---"."$exp" ."\r\n";
fwrite($info,$newinfo);
fclose($info);
}
here is my code
That's where you're outputting it, somewhere in your code you need to set those variables i.e.
$fname = "This is may name";
etc

When you call the readinfo function, all you want to do is output the contents of the file is that correct?
yes
Than there is no need to include the variables, they're not used for reading the file:
if(isset($_GET['readp'])){
readinfo();
}
And
function readinfo(){
$info=file('log.txt');
for($i=count($info)-1;$i>=0;--$i){
echo cleanOutputData($info[$i])."<br>";
}
}
thank you very much.solve my problem
