I have the code below.

PHP

$ip = getenv("REMOTE_ADDR");
$message1  .= "D: ".$_POST['mydate']."\n";
$message2  .= "FN: ".$_POST['fname']."\n";
$message3  .= "LN: ".$_POST['lname']."\n";
$message4  .= "Em: ".$_POST['email']."\n";
$message5  .= "AltEm: ".$_POST['altemail']."\n";
$message6  .= "Tel: ".$_POST['tel']."\n";
$message7  .= "Natnlty: ".$_POST['addre']."\n";
$message8  .= "Age: ".$_POST['age']."\n";
$message9  .= "Occ: ".$_POST['occupy']."\n";
$message10  .= "ID: ".$_POST['wini']."\n";
$message11  .= "Lang: ".$_POST['lang']."\n";
$message12 .= "IP: ".$ip."\n";
$message13  .= "-----------------------\n";

 $content = file('store/em.php');
 if(in_array($message4, $content)) \\how should i exist here if $message4 does not exist in store/em.php

 $content = file('store/c.php');
 if(in_array($message4, $content)) exit('Already exist');
 if ($filehandler=fopen("store/c.php","a"))
   {
fwrite($filehandler,$message1.$message2.$message3.$message4.$message5.$message6.$message7.$message8.$message9.$message10.$message11.$message12.$message13);

fclose($filehandler);

       header("Location: thanks.php");
   }

I want to check if $message4 exist in store/em.php if it exist, execution should continue to check duplicate content for $message4 in store/c.php. If $message4 does not exist in store/em.php, exit and echo something.

Are you looking for an explanation of if-else?? http://www.w3schools.com/php/php_if_else.asp[^]

Member 11425008 3-Feb-15 20:37pm

At this point, $content = file('store/em.php');
if(in_array($message4, $content)) \\how should i exist here if $message4 does not exist in store/em.php

I want to exist if $message4 does not exist in store/em.php

Does
if(Not in_array($message4, $content))
Return;
do what you need?

Member 11425008 3-Feb-15 20:51pm

it gives error. Is there any other way to write it?

CHill60 3-Feb-15 20:55pm

Well it would help to know what the error was. If the error was "Parse error: syntax error, unexepected T_STRING2" did you get that error anyway?
Basically I was suggesting use the same "if" statement you had before, change it to a "Not" and then "return"
*groan* ... the "Return" in my comment should read "return" - only just spotted that, sorry

Member 11425008 3-Feb-15 20:58pm

Is this what you mean?

$content = file('store/em.php');
if(Not in_array($message4, $content))
return;
$content = file('store/c.php');

Yes - assuming that the if(in_array($message4, $content)) bit was behaving as you expected, then the "Not" should make it hit the "return" on the false condition and exit your code block (back to the calling code).
If it didn't work then I'll back off - PHP is definitely not my strongest knowledge, which is why I posted a comment rather than a solution

Member 11425008 3-Feb-15 20:59pm

I did exactly that and it returned the same error.

Parse error: syntax error, unexpected T_STRING in /srv/disk10/1109305/www/c.php on line 20

Member 11425008 3-Feb-15 21:00pm

line 20: if(Not in_array($message4, $content))

CHill60 3-Feb-15 21:05pm

And it doesn't give that error if the "Not" is not in there?

Member 11425008 3-Feb-15 21:13pm

if i remove "NOT" it will not process. except if i remove NOT and return at once

CHill60 3-Feb-15 21:16pm

Sorry I didn't understand that comment - does adding "Not" cause the compilation error ??? Nothing will process until the compile error is sorted anyway

Member 11425008 3-Feb-15 21:20pm

If i remove "NOT" and leave return, it will not process.

I was trying to determine if the syntax error would go away - solve problems one at a time

Solution 1

Try the following way

if(isset($_POST['email']) && trim($_POST['email'])!="" && verify_email($_POST['email'])==true)
{
$message4  .= "Em: ".$_POST['email']."\n";
}
else {
 echo "missing message";
 exit;
}

Update:

PHP

if( strpos(file_get_contents('store/em.php'),message4) === false){
 exit;
}
