using regex to match age?

[darkfreaks]

i want to modify my search thing using file_get_contents to match the profile age instead of suspension reason.

 

 

in order to change this i need to match this. line.

<b>Age:</b> 16

 

 

i am trying to do something like

 

case($line=="<b>Age:</b>")

 

then inside of that put an age variable but i get nothing.

 

for age i did

$age= ($age < 18) ? 'minor' : 'adult';

 

but nothing works when i pass age into the line string

 

ultimately i want to make it so that if the matched age is less than 18 to say minor else pass as an adult.

This is probably what you want:

 

<?php

$string = '<b>Age:</b> 16';

if (preg_match('~<b>Age:</b> (\\d+)~', $string, $match)) {
    echo ((int)$match[1] < 18) ? 'minor' : 'adult';
}

?>

<?php

$string = '<b>Age:</b> 16';

if (preg_match('~<b>Age:</b> (\\d+)~', $string, $match)) {
    echo ((int)$match[1] < 18) ? 'minor' : 'adult';
}

?>

 

no.

If you are not sure of the age data and you need a tight regex you can use this.

 

$string = '<b>Age:</b> 16';

if (preg_match('~^<b>Age:</b> ([1-9][0-9]?|10[0-5])$~', $string, $match)) { //max age 105
    echo ((int)$match[1] < 18) ? 'minor' : 'adult';
}

 

else, if you are sure of the data, you can use this:

 

$string = '<b>Age:</b> 16';

if (preg_match('~^<b>Age:</b> (\d{1,3})$~', $string, $match)) {
    echo ((int)$match[1] < 18) ? 'minor' : 'adult';
}

 

or even:

 

$pattern = '^<b>Age:</b> (\d+)$';

 

curious, where are you getting the contents of $line?

[darkfreaks]

yeah it is all messed up now.

 

<?php

$submit = isset($_POST['submit'])?$_POST['submit']:false;
  if ($submit) {
   $url = 'http://vampirefreaks.com/profile.php?user=';
      $user = $_POST['user'];
      $file = file($url.$user);//retrieves url and puts into plain text format
      foreach ($file as $lines) {
          $line=strip_tags($lines);
          $line=trim($line);
          if ($line != ''||!empty($line)) {  
          



//echo "$line<br>\n"; // debug code
              $line = str_replace('LOTCC.bcp();', ' ',$line);//strip out multiply.com javascript code
              $line = preg_replace('/\s+/', ' ', $line); //strip out white space
              $line = preg_replace('/\s+$/', ' ', $line);//strip out white space
              $redopen="<font color=red>";
              $greenopen="<font color=green>";
              $pinkopen="<font color=#f600ff>";
              $blueopen="<font color=blue>";
              $purpleopen="<font color=purple>";
              $close="</font>";
            
            switch($line){
case ($line =='THIS USER DOES NOT EXIST'||$line == 'Error Retreiving user info'):
$message ="$redopen this user is dead!$close";
break;
case (preg_match('~^<b>Age:</b> ([1-9][0-9]?|10[0-5])$~', $line, $match)):
$message= ((int)$match[1] < 18) ? ''.$redopen.'minor Posting in 18+ Classifieds'.$close.'' : $match[1];
break;
}}}}
  if($message){echo $message;}else{echo $form;}

I think it would be best if you glanced at the switch statement syntax:

[darkfreaks]

yeah i think i will just remove the switch and use ternaries.

yeah i think i will just remove the switch and use ternaries.

 

Let us know when this has been solved.
