Deanznet Posted June 17, 2013 Share Posted June 17, 2013 Hey! Need some help with my string search! I have been working on this script for a while but im STUCK! I have a FILE.txt Inside it has a bunch of random STUFF EXAMPLE: <html><stuff>dsadfsdasfasfasfasfsafasfasfasf superman was awsome hehe https:\/\/superman.com\/Jmd8KKtjIj <html><stuff>dsadfsdasfasfasfasfsafasfasfasf superman was awsome hehe https:\/\/superman.com\/Jmd8KKtjIj <html><stuff>dsadfsdasfasfasfasfsafasfasfasf superman was awsome hehe https:\/\/superman.com\/Jmd8KKtjIj I made a script like this. <?php $search = 'https:\/\/superman.com\/'; // Read from file $lines = file('file.txt'); echo"<html><head><title>SEARCH RESULTS FOR: $search</title></head><body>"; foreach($lines as $line) { // Check if the line contains the string we're looking for, and print if it does if(stristr($line,$search)) // case insensitive echo "<font face='Arial'> $line </font><hr>"; } ?> But it actually echos the whole LINE! PLUS i need it to actually grab 10 characters after the search string so i actually need it just to grab https:\/\/superman.com\/Jmd8KKtjIj - In THIS CASE it would of echoed it 3 TIMES since its 3 of them in their. Also any way i can FILTER out the extra slants it puts in ? https:\/\/superman.com\/Jmd8KKtjIj is suppose to be https://superman.com/Jmd8KKtjIj Thanks!

ginerjm Posted June 17, 2013 Share Posted June 17, 2013 Don't understand at all what your $search string is doing. As for showing the whole line - of course it does. What would make it NOT do that? Your run a stristr but you don't capture the result and don't use that result to limit the output.

litebearer Posted June 18, 2013 Share Posted June 18, 2013 1. presumes lines in file.txt terminate with \n2. presumes $needle only appears once in a line <?php $needle = 'https:\/\/superman.com\/'; $lines = file('file.txt'); echo"<html><head><title>SEARCH RESULTS FOR: $needle</title></head><body>"; foreach($lines as $line){ if(stristr($line,$needle)){ $temp_array1 = explode($needle, $line); if(strlen($temp_array1[0])>10){ $value = substr($dtemp_array1[0], -10) . $needle; }else{ $value = $temp_array1[0] . $needle; } if(strlen($temp_array1[1])>10){ $tail = substr($dtemp_array1[1], 0, 10); }else{ $tail = $temp_array1[1];} echo "<font face='Arial'>" . $value . $tail .

litebearer Posted June 18, 2013 Share Posted June 18, 2013 My typo... this: if(strlen($temp_array1[0])>10){ $value = substr($dtemp_array1[0], -10) . $needle; }else{ $value = $temp_array1[0] . $needle; } if(strlen($temp_array1[1])>10){ $tail = substr($dtemp_array1[1], 0, 10); }else{ $tail = $temp_array1[1];} should be: if(strlen($temp_array1[0])>10){ $value = substr($temp_array1[0], -10) . $needle; }else{ $value = $temp_array1[0] . $needle; } if(strlen($temp_array1[1])>10){ $tail = substr($temp_array1[1], 0, 10); }else{ $tail = $temp_array1[1];} $tail will contain any text that follows your search up to 10 characters Link to comment https://forums.phpfreaks.com/topic/279277-php-string-search/#findComment-1436518 Share on other sites More sharing options...

litebearer Posted June 18, 2013 Share Posted June 18, 2013 Untested... Put this right after $lines = file('file.txt'); $c = count($lines); if($c>30) { $lines = array_slice($lines, 0, 30); } Link to comment https://forums.phpfreaks.com/topic/279277-php-string-search/#findComment-1436597 Share on other sites More sharing options...
