Question

I have a page.html with just 48 in it. I can’t get this if statement to work.

<?php 
  $myFile = 'http://site.com/page.html';
  $content = file_get_contents($myFile);
?>
<?php $num = "48"; ?>
<?php if ($content == $num): ?>
    true
<?php else: ?>
    false
<?php endif;  ?>

If I do this it works.

<?php if ($content == 48): ?>
    true
<?php else: ?>
    false
<?php endif;  ?>

How can I change this to make it work?

Answer 1

Think this should work:

<?php 
  $myFile = 'http://site.com/page.html';
  $content = file_get_contents($myFile);
?>
<?php $num = "48"; ?>
<?php if (trim($content) == $num): ?>
    true
<?php else: ?>
    false
<?php endif;  ?>

..by using trim() which removes these characters:

• ” ” (ASCII 32 (0x20)), an ordinary space.
• “\t” (ASCII 9 (0x09)), a tab.
• “\n” (ASCII 10 (0x0A)), a new line (line feed).
• “\r” (ASCII 13 (0x0D)), a carriage return.
• “\0” (ASCII 0 (0x00)), the NUL-byte.
• “\x0B” (ASCII 11 (0x0B)), a vertical tab.
