Scenario:
I have a php file that I'm using by a zip code lookup form. It has number arrays of five digit zip codes running anywhere from 500 to 1400 zip codes. So far it works but I get PHP sniffer warnings in my code editor (Brackets) that I'm exceeding the 120 character limit.
Question:
Will this stop my PHP from running in certain browsers?
Do I have to go to every 120 characters and do a return just to keep the line length in compliance?
It appears, I need to place these long strings into a database and call them in to the array rather than hang them all inside the PHP.
I am front-end designer so a lot to learn.
<?php
$zip = $_GET['zip']; //your form method is post
// Region 01 - PersonOne Name Zips
$loc01 = array (59001,59002,59003,59004,59006);
// Region 02 - PersonTwo Name Zips
$loc01 = array ("00001","00002","00003","00004","00006");
// Above numeric strings could include 2000 zips
// Region 01 - PersonTwo Name Zips
if (in_array($zip, $loc01)) {
header("Location: https://company.com/personone");
// Region 02 - PersonTwo Name Zips
if (in_array($zip, $loc02)) {
header("Location: https://company.com/persontwo");
Question: Will this stop my PHP from running in certain browsers?
No, PHP runs entirely on the server. Browsers have nothing to do with PHP -- browsers are clients. Languages like HTML, CSS and (most) JavaScript are browser languages, but PHP is only server-side.
Do I have to go to every 120 characters and do a return just to keep the line length in compliance?
No, but I would highly suggest using a database to store tons of records like this. It's exactly what databases are for. Alternatively you could put them in a file and simply read the file in with PHP's file_get_contents function.
I will try to:
Add each array into a mysql database record.
Create a PHP script that fetches each array and applies it to the
respective location.
This will eliminate the bloated lines of arrays numbers in PHP.
BTW, I also need to define these as 5 digit numeric strings as many of the zips start with one or two zeros which are ignored by the POST match.
Thanks everyone for the input.

I need a simple php script which needs to find files on server after reading Number column from database, copy files to another directory and then replace specific strings in saved files. For example we have files
20160107-151620_03216488727-all.mp3
20160418-105509_03225545395-all.mp3
We need to replace (03216488727, 03225545395) with the strings from database. Here is my database info:
Number Policy Number Month
03216488727 123456788 2016-06
03225545395 123433339 2016-06
so after the replacement files will be
20160107-151620_123456788-all.mp3
20160418-105509_123433339-all.mp3
Please help.
Have a look on the str_replace() function.

Hello, recently I took part in a programming contest (PHP). I tested the code on my PC and got the desired output but when I checked my code on the contest website and ideone, I got wrong output. This is the 2nd time the same thing has happened. Same PHP code but different output.
It is taking input from command line. The purpose is to bring substrings that contact the characters 'A','B','C','a','b','c'.
For example: Consider the string 'AaBbCc' as CLI input.
Substrings: A,a,B,b,C,c,Aa,AaB,AaBb,AaBbC,AaBbCc,aB,aBb,aBbC,aBbCc,Bb,BbC,BbCc,bC,bCc,Cc.
Total substrings: 21 which is the correct output.
My machine:
Windows 7 64 Bit
PHP 5.3.13 (Wamp Server)
Following is the code:
<?php
$stdin = fopen('php://stdin', 'r');
while(true) {
$t = fread($stdin,3);
$t = trim($t);
$t = (int)$t;
while($t--) {
$sLen=0;
$subStringsNum=0;
$searchString="";
$searchString = fread($stdin,20);
$sLen=strlen($searchString);
$sLen=strlen(trim($searchString));
for($i=0;$i<$sLen;$i++) {
for($j=$i;$j<$sLen;$j++) {
if(preg_match("/^[A-C]+$/i",substr($searchString,$i,$sLen-$j))) {$subStringsNum++;}
}
}
echo $subStringsNum."\n";
}
die;
}
?>
Input:
2
AaBbCc
XxYyZz
Correct Output (My PC):
21
0
Ideone/Contest Website Output:
20
0
You have to keep in mind that your code is also processing the newline symbols.
On Windows systems, newline is composed by two characters, which escaped representation is \r\n.
On UNIX systems including Linux, only \n is used, and on MAC they use \r instead.
Since you are relying on the standard output, it will be susceptible to those architecture differences, and even if it was a file you are enforcing the architecture standard by using the flag "r" when creating the file handle instead of "rb", explicitly declaring you don't want to read the file in binary safe mode.
You can see in in this Ideone.com version of your code how the PHP script there will give the expected output when you enforce the newline symbols used by your home system, while in this other version using UNIX newlines it gives the "wrong" output.
I suppose you should be using fgets() to read each string separetely instead of fread() and then trim() them to remove those characters before processing.
I tried to analyse this code and that's what I know:
It seems there are no problems with input strings. If there were any it would be impossible to return result 20
I don't see any problem with loops, I usually use pre-incrementation but it shouldn't affect result at all
There are only 2 possibilities for me that cause unexpected result:
One of the loops iteration isn't executed - it could be only the last one inner loop (when $i == 5 and then $j == 5 because this loop is run just once) so it will match difference between 21 and 20.
preg_match won't match this string in one of occurrences (there are 21 checks of preg_match and one of them - possible the last one doesn't match).
If I had to choose I would go for the 1st possible cause. If I were you I would contact concepts author and ask them about version and possibility to test other codes. In this case the most important is how many times preg_match() is launched at all - 20 or 21 (using simple echo or extra counter would tell us that) and what are the strings that preg_match() checks. Only this way you can find out why this code doesn't work in my opinion.
It would be nice if you could put here any info when you find out something more.
PS. Of course I also get result 21 so it's hard to say what could be wrong
Currently I need to merge that 50+ PDF files into 1 PDF. I am using PDFTK. Using the guide from: http://www.johnboy.com/blog/merge-multiple-pdf-files-with-php
But it is not working. I have verified the following:
I have tried the command to merge 2 pdfs from my PHP and it is working.
I have echo the final command and copied that command and paste into command prompt and run manually and all the 50 PDFs are successfully merged.
Thus exec in my PHP and the command to merge 50 PDFs are both correct but it is not working when done together in PHP. I have also stated set_time_limit(0) to prevent any timeout but still not working.
Any idea what's wrong?
You can try to find out yourself:
print exec(str_repeat(' ', 5000) . 'whoami');
I think it's 8192, at least on my system, because it fails with strings larger than 10K, but it still works with strings shorter than 7K
I am not sure if there is a length restriction on how long a single command can be but I am pretty sure you can split it accross multiple lines with "\" just to check if thats the problem. Again I dont think it is... Is there any error output when you try to run the full command with PHP and exec, also try system() instead of exec().
PDFTK versions prior to 1.45 are limited to merge 26 files cuz use "handles"
/* Collate scanned pages sample */
pdftk A=even.pdf B=odd.pdf shuffle A B output collated.pdf
as you can see "A" and "B" are "handles", but should be a single upper-case letter, so only A-Z can be used, if u reach that limit, maybe you script outputs an error like
Error: Handle can only be a single, upper-case letter
but in 1.45 this limitation was removed, changelog extract
You can now use multi-character input handles. Prior versions were
limited to a single character, imposing an arbitrary limitation on
the number of input PDFs when using handles. Handles still must be all
upper-case ASCII.
maybe you only need update your lib ;)
If I use a local filename, the filename is properly copied, however, if you leave local filename empty, you are supposed to receive the content of the file.
Example code:
$stat = $sftp->get('xmlfile.cml','xmlfile.xml');
print "$stat";
(This works fine)
$xmlcontent = $sftp->get('cp1301080801_status.xml');
print "Content of file = $xmlcontent<>";
*(This prints what looks more like the stat of the file instead of the content. It starts with the date (which is the modofoed timestamp of file, followed by some numbers and the name of the web server repeated about 10 times with a number after it that increases each time - like maybe a port number or byte offset) *
It would make things easier if I didn't have to fopen the local file after the transfer. Anyone have an idea what is going on here?
Can you post a copy of the logs? Here's an example of how to get them:
http://phpseclib.sourceforge.net/ssh/examples.html#logging
Note the define() and the $ssh->getLog() stuff.
As for the specific problem you're having... what does print "$stat" do? It should print "1".
Also, fwiw, you're opening two different files in your example. My best guess, atm, is that you're thinking you're opening the same files and expecting the content to be the same when in fact they should be different and that what you're getting with both of the $sftp->get()'s is, in fact, correct.
The logs will tell us for sure.
Is there a command line utility or a php/py script that will generate a html diff so that multiple files can be compared in order to compare 4 or more files.
Each of my files have max of 10k lines each.
Note: these files are plain text files . not html . Only contain A-Za-z0-9=., . and no HTML tags
It depends what type of data you're comparing/analyzing.
The basic solution is
file_get_contents gives you strings of the file data
strcmp will do a "binary-safe compare" of the data
You will probably want to explode() your data to delimit it somehow, and compare sections of the data.
Another option is to delimit, loop through, and make a "comparison coefficient" which would indicate to what degree the files deviate from a norm. For example, File 1 has cc=3, file 4 has cc=8. File 4 would be a closer match.
A final problem you'll run into is the memory limit on the server computer. You can change this in php.ini.
//EDIT
Just noticed the diff tag, but I'll leave this up anyway in case it helps somehow.
