PHP - Split A String At A Certain Number Of Characters But Not In The Middle Of A Word

I need to split a string, but in a very unusual way.

$string1 = "HelloWorld"
$string2 = "AlphaBravo"
$string3 = "BreakMeUp"

I need the following split at each upppercase letter for this output

Hello World
Alpha Bravo
Break Me Up

I've been trying to figure out how to split up strings such as the following:

A54a1, 23b, FX49s1, R231z, 77

I would like to split them up and add them to individual arrays that are as follows:

index[0] -> alphabetical characters, if any, prior to the first number, if any
index[1] -> numerical characters, as a number, up until the following alphabetical character
index[2] -> alphabetical character(s), if any
index[3] -> numerical characters following the second alphabetical character set, if any

So, for example, the above strings would be separated like this:
A54a1 == ('A', 54, 'a', 1)
23b == (, 23, 'b',,)
FX49s1 == ('FX', 49, 's', 1)
R231z == ('R', 231, 'z',,)
77 == (,77,,)

I've looked into things like strpos(), but I can't figure how to determine whether a character is alphabetic or numeric.  And yes, I am familiar with the function is_numeric().  Just don't know how to throw it all together to accomplish what I need.

hi everyone,
i have a string as this one: 45,3455,66,8900,2,49,88,8,909

I need to print it with a new line every 4 numbers, as this one:
45,3455,66,8900,
2,49,88,8,
909

How can i do this?

many thanks

Hello,

I have a string that contains a directory path much like: "/images/icons" and I want to take that string through a function and explode it into an array of directories that with add my directory structure array:

images icons
Then if I were to send the string "/data/documents" to the function it would append to the existing array:
images icons data documents
Here's the code that I've got thus far:
<?php

$global_structure = array();

generate_structure("./images/icons");
generate_structure("./data/documents");

function generate_structure($directory)
{
    if(!is_dir($directory))
        return false;

    $directory_structure = explode("/", $directory);

    // do something here to iterate over $global_structure and add new directories to equal to current directory path making the value an empty array.
}

?>

I am trying to figure out how to have an if statement in the middle of strings I am trying to concatenate. I have a from that has a address1 and address2, where address2 often does not exist. So I want to only add that line if there is actually content. I was trying something like the following, but that is giving me an error. I am pretty new to php, so I can't seem figure it out. Any help would be greatly appreciated.

Code: [Select]
"<p><strong>Address 1: </strong><br>" . $address1 . "<br>"
if ( isset($address2) ) { echo . $address2 . "<br>" }
. $city . ", " . $state . " " . $zip . "</p>"

We have a database that shows for example:

2500-5000

5000-10000

10000-15000

15000-20000

I need to show in a screen what people are have 3000 followers, and as such as grouped into that 2500-5000.

The best way I can see how to do this, is to run through the database table for these values.

Then for each value, put the first and second set of numbers into two respective variables, say $low, $high.

Then find those people who are on a particular platform with followers between those two values.

So how do I turn $row->followsrange (which might be for example: "2500-5000"), into:

$low = 2500
$high = 5000.

Many thanks.  ps  I have a feeling the hyphen might play a bit part, as it cannot be done by the amount of characters..........

My string is like this:

line 1
line 2
....
line 3453
line 3454
etc...

I want to split the string into chunks of 500 lines, do something with those chunks and then reassamble the main $string again. The last chunk doesn't need to be 500 lines it can be less.

How can I do it?

Hi! So what I'm trying to do is split a multi dimensional array of strings ( each containing 3 strings inside of 1 array ) so I can write the results to a file.

So say I had a bunch of strings inside 1 array : 

class File {
    function WriteFile ( $filename, $content ) {
        $list = [
            $content
        ];
        $delimiters = File :: checkDelimiter (
            $content, 
            true, 
            false
        );
        $fp = fopen (
            $filename, 'w'
        );
        foreach ( $list as $fields ) {
            $fields = File :: SplitFileByDelimiter (
                $fields, 
                ",", 
                3
            );
            file_put_contents (
                $filename, $fields
            );
        }
        fclose ( $fp );
    }
}

$file-> File :: WriteFile (
    $filepath . $filename, 
    "TEST!, TEST!, TEST!, " . 
    "TEST!, TEST!, TEST!, " . 
    "TEST!, TEST!, TEST!"
);
	

Instead of writing : 

TEST!, TEST!, TEST!, TEST!, TEST!, TEST!, TEST! ,TEST!, TEST!, TEST!
	

to the file in a straight line, it should write it like this : 

TEST!, TEST!, TEST!, 
TEST!, TEST!, TEST!, 
TEST!, TEST!, TEST!
	

Any help is ABSOLUTELY appreciated!

Dear All PHP Master,
Kindly need your help (I'm sorry my Bad English), I'm new in PHP and OOP in PHP please help to check I have class to convert number to words below, but when I'm running it the result in browser is error with error message :
  Notice: Undefined variable: str in C:\xampp\htdocs\latihan\oop.php on line 16
  Notice: Undefined variable: str in C:\xampp\htdocs\latihan\oop.php on line 14
  Notice: Undefined variable: str in C:\xampp\htdocs\latihan\oop.php on line 16
  seratus dua puluh tiga juta empat ratus lima puluh enam ribu tujuh ratus delapan puluh sembilan

here it's my code to convert number to words :
<?php 
   Class Terbilang {

      Public function terbilang() {
         $this->dasar = array(1=>'satu','dua','tiga','empat','lima','enam','tujuh','delapan','sembilan');
         $this->angka = array(1000000000000,1000000000,1000000,1000,100,10,1);
         $this->satuan = array('triliun','milyar','juta','ribu','ratus','puluh','');
      }
      
      Public function eja($n) {
         $i=0;
         while($n!=0){
            $count = (int)($n/$this->angka[$i]);
            if($count>=10) $str .= $this->eja($count). " ".$this->satuan[$i]." ";
            else if($count > 0 && $count < 10)
            $str .= $this->dasar[$count] . " ".$this->satuan[$i]." ";
            $n -= $this->angka[$i] * $count;
            $i++;
         }
         $str = preg_replace("/satu puluh (\w+)/i","\\1 belas",$str);
         $str = preg_replace("/satu (ribu|ratus|puluh|belas)/i","se\\1",$str);
         return $str;
      }
   }
   
   $bilangan = new Terbilang;
   echo $bilangan -> eja(123456789);   //shouldbe show :seratus dua puluh tiga juta empat ratus lima puluh enam ribu tujuh ratus delapan puluh sembilan
?>

I have a regex that validates a string. I want to ensure there is no space in the string. Thus far I have used the negative look ahead regex construct as shown below to match strings without spaces.

(?!.*(\s))

While this prevents space in between a word, all strings with space characters at the end or beginning are getting validated. I do not want that at all.   This is the full regex script below:

$string = "#JebiamgoOeing0";
if (preg_match('/^.*(?=.{8,})(?!.*([A-Za-z0-9])\1{1})(?=.*[a-z])(?=.*[A-Z])(?!.*(\s))(?=.*[\d])(?=.*[\W]).*$/', $string))
{
    "do something";
}
else
{
   "do something else";
}

I need help in resolving this.   Thank you.

Hey

I have a string that looks like the following:
Quote

top-php-tutorials-2.html


I have a script that cycles through each page. The 2 in the quote above is the page number.

How can I extract the number between the - and the .html and replace it with another number?

I've tried
Code: [Select]
substr($engine->selectedcaturl, 0,-6).$v.".html"But then I realised this only works for numbers that are 1 digit long

Any input would be appreciated

I have the following code in my index.php:

                   <?php
                    $files = array();
                    $files = glob('download/*.iso');
                    $file = $files[count($files) - 1];
                    $strlen ( string $file ) : int  /* length of $file */
                    $filelen = $strlen -9  /* length of unwanted characters - "download/" */
                    $filename =          /* how do I get the filename starting at the 10th position  */
                   ?>

                     <div class="container">
                        <div class="divL">                       
                            <h3>Get the latest version of FoxClone iso</h3>
                          <a href="<?php echo "/{$file}";?>"><img src="images/button_get-the-app.png" alt="" width="200" height="60"></a>

I'd like to replace "Get the latest version of FoxClone iso" in the next to last line with "Get Foxclone "<?php echo "/{$filename}";?>". How do I extract just the file name from $file? I know that I have to:

1. get the length of $file
2. subtract the number of unwanted character to determine the start character (In this case, start at 10th character)
3. and extract everything from the 10th character to length of $file.

Step 3 is where I just don't know how to accomplish the task. I'd appreciate some help on this.

Thanks in advance,
Larry

Hey folks! Happy what ever you are celebrating

I am trying to limit the number of characters to 200 that this array echos. I have tried a few things... I have tried using "substr($arr_tem, 0, 200)" but obviously it is not working... but I think I am close-ish. Any assistance would be great!
 
Code: [Select]
###print array###
echo (implode(", ", array_keys($arr_tem)));
Thanks!

Hey...

I'm trying to echo the title of the news in the right column but I just want to display maximum of 25 characters how can I do it?

thanks

I'm pretty sure this is really simple to do using the count function, but I am having a hard time finding examples on how to count the number of times a "SPECIFIC" word occurs in a file. For example, I just want to display how many times "this-word" occurs in "http://www.mysite.com/logfile.log". Any help would be appreciated.
