PHP中的字符串比较

Question

I feel like the biggest fool on the planet earth. But I am looping through a text file and attempting to compare each line and find the line breaks... You know... " ". But I can't seem to compare the strings!!!! Here is what I am doing.

    $filename = 'StatesCities.txt';
$file = file($filename);
$matchedLines = array();

foreach($file as $line) {     
    $matchesLines[] = $line;
    if(strcmp($line, "La Mesa") == 0)
    {
        echo("Yeah");
    }
    echo($line);
    echo("<br />");
}

Answer 1

Are you trying to remove the line breaks? If that's the case then you can explode them.

$file = file_get_contents( $file_path );
$page = explode( "
", $file );
//Now they're gone

foreach( $page as $line )
{
  if( strpos( $line, 'searchfor' ) !== false )
  {
     //do this
  }
}

The strpos is how I usually search in a string, just make sure to use !== which checks for false not false or 0. If the string your looking for has a strpos of 0 ( first character ) it would return a false positive if you don't check for the type with !==. Good luck.
