Use of IF statement

[pabs1983]

Hi guys,

First post here. Straight into it.

 

I am wondering if i can get some help. I know how to use the IF statement for a full string, however i am looking for it to check the start of a string. It is a project for work, where there are files that come in, these files start with 3 letters and a number followed by a : sign. each department has a different combination and i would it to be able to read that first part and know what department it is. Is this possible?

<?php

  $s = 'dep334455';
  if (substr($s,0,2) == 'dep') {
    echo "belongs to dep";
  }

?>

hey,

you could use the strpof function to locate characters in a sting for instance

 

$find  = 'whatyouarelookingfor;
if (strpos($whatyourlookingin, $find) == true){ //do stuff in here }
else{//do stuff in here}

 

I think that should work. I use the same method in one of my scripts.

If it doesnt work post your code and the output for us to see!

if (??? == substr($str,0,3))

 

$str's value will not change after using substr() unless you set $str as substr(...) :

 

$str = substr($str,0,3);

Some of the departments codes are longer than others (some have 4 letters, some have 3, etc) can i not just check all the characters before ':' ?

try

 

<?php

  $s = 'dep334455';
  if (preg_match('/^dep/i',$s)) {
    echo "belongs to dep";
  }

?>

Your probably going to need to be a little more specific in the description of what exactly these strings look like, but maybe....

 

<?php

  $s = 'dep2345:';
  preg_match('/^(.*):/',$s,$matches);
  if ($matches[0] == 'dep2345') {
    echo "belongs to dep";
  }

?>

 

helps.

the strings look like

'xxx1234:filename.xxx'

 

however, it could also have more or less characters in the first section so it could be 'xxxxx12345:...'

This is what i have so far:

 

<?php

 

  $s = $_REQUEST['file];

 

  if (preg_match('/^ITS0001/i',$s))

    echo "<meta http-equiv=refresh content='1;url=Department/ITSales.php?file=";

    echo $_REQUEST['file'];

    echo "' />";

   

  elseif (preg_match('/^PERS0001/i',$s))

    echo "<meta http-equiv=refresh content='1;url=Department/Personnel.php?file=";

    echo $_REQUEST['file'];

    echo "' />";

 

 

  else

    echo "<h1>Not Recognised Format</h1>";

 

?>

 

This works for ITS0001 file, but not for PERS0001. Instead i get an error

 

'Parse error: syntax error, unexpected T_ELSEIF in /home/www/XXXXXXXXXX/target.php on line 16'

please put your could in blocks like the following

 

 

<?php

  $s = $_REQUEST['file];
  
  if (preg_match('/^ITS0001/i',$s)) 
  {
    echo "<meta http-equiv=refresh content='1;url=Department/ITSales.php?file=";
    echo $_REQUEST['file'];
    echo "' />";
  } 
  elseif (preg_match('/^PERS0001/i',$s))
  {
    echo "<meta http-equiv=refresh content='1;url=Department/Personnel.php?file=";
    echo $_REQUEST['file'];
    echo "' />";
  }
  else
  {
    echo "<h1>Not Recognised Format</h1>"; 
  }
?>
