PHP - Split A String At A Certain Number Of Characters?

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.
}

?>

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..........

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!

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?

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...

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

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!

While we're on the subject, is there a way to ensure that the first letter of a name is captalized, and the rest lowercase?  Or is this best handled later on, when the name is being used and called from the DB.

PS: some of us comment are code as to WHAT we are doing because we're just not that good yet, and we need to explain it to ourselves.

Does anybody know of a function or a way of letting me get the string between whatever characters? Say I had [SOMEWORD] text [SOMEWORD] then how could I go about getting the value "text", please note I'm not trying to make bbcode or similar.

Hello Everyone,

I am working on a project I pull the field names from the database. I am trying to remove the underscore (_) when the field name is displayed. Does anyone know how I would do that?

Here is the code that I am working with
Code: [Select]
$i = 0;
    while ($i < mysql_num_fields($fieldnamesquery_result)) {
        $meta = mysql_fetch_field($fieldnamesquery_result, $i);
        if (!$meta) {
            echo "No information available";
        }

        $meta = str_replace("_", " ", $meta);

        $tablecolumn .= "<p>" . $meta->name . ":<input type='text' name='" . $meta->name . "' id='" . $meta->name . "' /></p>";
        $i++;

How I can explode by a series of characters (not one single character)? For example, divide the string to an array by any of these characters "," and ";" and "."

$string = "this, that;some.word;second";

I want to put all of these words into an array.

Hi, I am trying to search a string for a string of characters in this order ../ and carry out relevant if statements but it returns the same result every time. On echoing my $pos, $pos2, $pos3 and $pos4 variables the first two come back 0 and they are the strings that do contain ../ but the if statements perform the same? I don't understand, any ideas? Thanks...

Code: [Select]
<?php $logo = $info ['logo'];
$pos = strpos($logo, "../");//check if image contains ../
if ($pos == 0) {}
else {
$logo = substr($logo, 3);}

$image1 = $info ['image1'];
$pos1 = strpos($image1, "../");//check if image contains ../
if ($pos1 == 0) {}
else {
$image1 = substr($image1, 3);}

$image2 = $info ['image2'];
$pos2 = strpos($image2, "../");//check if image contains ../
if ($pos2 == 0) {}
else {
$image2 = substr($image2, 3);}

$image3 = $info ['image3'];
$pos3 = strpos($image3, "../"); //check if image contains ../
if ($pos3 == 0) {}
else {
$image3 = substr($image3, 3);}

?>

Am looking forward to removing all the numeric characters upto and including the leading "/" in
