darkfreaks Posted August 20, 2012 Share Posted August 20, 2012 why not use Regex to match the phone number // validate a phone number if( !preg_match("/^([1]-)?[0-9]{3}-[0-9]{3}-[0-9]{4}$/i", $phone) ) { echo 'Please enter a valid phone number'; } Link to comment https://forums.phpfreaks.com/topic/267323-filter-data-from-one-input/#findComment-1370760 Share on other sites More sharing options...

MMDE Posted August 20, 2012 Share Posted August 20, 2012 preg_replace("/$phone_number/", "", $phone_number_list); ^ This will leave empty lines, so you might want to make sure you remove those empty lines too. http://php.net/manual/en/function.preg-replace.php Link to comment https://forums.phpfreaks.com/topic/267323-filter-data-from-one-input/#findComment-1370769 Share on other sites More sharing options...
Drummin Posted August 20, 2012 Share Posted August 20, 2012 Maybe this is a little over the top, creating arrays etc. <?php if (isset($_POST['listnumbers'])){ $listnumbers = nl2br(trim($_POST['listnumbers'])); $listnumbers = explode('<br />', $listnumbers); $Newlist=array(); foreach ($listnumbers as $numbers){ $numbers = str_replace("\r", "", $numbers); $numbers = str_replace("\n", "", $numbers); $numbers = preg_replace('~^(\<br /\>,/\n)+~', '', $numbers); $Newlist[] = $numbers; } $searchnumber = trim($_POST['searchnumber']); if (in_array($searchnumber,$Newlist)){ $number_key = array_search($searchnumber,$Newlist); unset($Newlist[$number_key]); } } ?> <html> <body> <?php echo "<pre>"; echo "<br />listnumbers<br />"; print_r($listnumbers); echo "<br />Newlist<br />"; print_r($Newlist); echo "<br />POST<br />"; print_r($_POST); echo "</pre>"; ?> <form method="post" action=""> <textarea name="listnumbers"> <?php echo (isset($Newlist)? implode(' ', $Newlist):''); ?> </textarea><br /> <textarea name="searchnumber"></textarea><br /> <input type="submit" value="Check Number" /> </form> </body> </html> Link to comment https://forums.phpfreaks.com/topic/267323-filter-data-from-one-input/#findComment-1370775 Share on other sites More sharing options...
Christian F. Posted August 20, 2012 Share Posted August 20, 2012 firstminister: Look into "array_unique ()" as that will do exactly what you're looking for. Drummin: Why replace the newlines with br tags, only to explode on them? Much better to explode the newlines right away. Your code could easily have been reduced to three lines, using the array_unique () and stripping away all unnecessary operations.

firstminister Posted August 20, 2012 Author Share Posted August 20, 2012 Ok, I checked the code, but this is the problem..

firstminister Posted August 20, 2012 Author Share Posted August 20, 2012 Christian I understand.. but like is just a simple script.. anyway if you can help me to modify it and can filter more numbers, i'll be thankful..

Drummin Posted August 20, 2012 Share Posted August 20, 2012 As pointed out, for single number removal a simple preg_replace will do the job. <?php if (isset($_POST['listnumbers'])){ $phone_number_list = trim($_POST['listnumbers']); $phone_number = trim($_POST['searchnumber']); $phone_number_list = preg_replace("/$phone_number/", "", $phone_number_list); $phone_number_list = str_replace(PHP_EOL.PHP_EOL, PHP_EOL, $phone_number_list); } ?> <html> <body> <form method="post" action=""> <textarea name="listnumbers"><?php if (isset($phone_number_list)){echo "$phone_number_list";} ?> </textarea><br /> <textarea name="searchnumber"></textarea><br /> <input type="submit" value="Check Number" /> </form> </body> </html> If however if your needing to remove a list of numbers from another list of numbers this approach won't work and you will probably need to build an array for each input and then filter out matches within a foreach loop.

Drummin Posted August 20, 2012 Share Posted August 20, 2012 This should do it. <?php if (isset($_POST['listnumbers'])){ $Newlist = explode(PHP_EOL, trim($_POST['listnumbers'])); $Searchlist = explode(PHP_EOL, trim($_POST['searchnumbers'])); $Newlist = array_diff($Newlist,$Searchlist); $phone_number_list = implode(PHP_EOL,$Newlist); } ?> <html> <body> <form method="post" action=""> <textarea name="listnumbers"><?php if (isset($phone_number_list)){echo "$phone_number_list";} ?> </textarea><br /> <textarea name="searchnumbers"></textarea><br /> <input type="submit" value="Check Number" /> </form> </body> </html> Link to comment https://forums.phpfreaks.com/topic/267323-filter-data-from-one-input/#findComment-1370883 Share on other sites More sharing options...

firstminister Posted August 20, 2012 Author Share Posted August 20, 2012 Oh perfect! it works, but how can I show the new filtered numbers, in the same page, not in the textarea and per line? example: Results filtered numbers: 12345 1234576 564476 3433243 66655434 Link to comment https://forums.phpfreaks.com/topic/267323-filter-data-from-one-input/#findComment-1370892 Share on other sites More sharing options...
Drummin Posted August 20, 2012 Share Posted August 20, 2012 Copy that isset echo line I have between the textarea tags an place where you want it. If you are going to use it for display, you'll probably want to change that last line to implode with a break tag. $phone_number_list = implode("<br />",$Newlist); Link to comment https://forums.phpfreaks.com/topic/267323-filter-data-from-one-input/#findComment-1370894 Share on other sites More sharing options...

Drummin Posted August 20, 2012 Share Posted August 20, 2012 Huh? You put in these number into the first textarea and 6 into the second textarea and it pulls that six out.
