I want to trim this string after "=" and before ";"
com=8af14f8b9d5be16e807ab9e0ed1d7edb:b6668c681f9d3bd2ad4ae31a8b6c7f2859939a75;
so that it echoes 8af14f8b9d5be16e807ab9e0ed1d7edb:b6668c681f9d3bd2ad4ae31a8b6c7f2859939a75

You can use the str_replace function to replace multiple values by, in this case, nothing:
str_replace(array('com=', ';'), '', $string);

This can also work:
parse_str(trim(
'com=8af14f8b9d5be16e807ab9e0ed1d7edb:b6668c681f9d3bd2ad4ae31a8b6c7f2859939a75;'
, ';'));
echo "$com\n";

Try this:
$value="aaaacom=8af14f8b9d5be16e807ab9e0ed1d7edb:b6668c681f9d3bd2ad4ae31a8b6c7f2859939a75;";`
$pos=strpos($value,"=");
echo substr($value,$pos+1,strlen($value)-($pos+2));

You can use a regex:
$str = 'com=8af14f8b9d5be16e807ab9e0ed1d7edb:b6668c681f9d3bd2ad4ae31a8b6c7f2859939a75;';
echo preg_replace('/([a-z]+)=(.*);/', '\2', $str);
But it looks like a .ini file, then maybe you want this:
Try this:
$ini = 'com=8af14f8b9d5be16e807ab9e0ed1d7edb:b6668c681f9d3bd2ad4ae31a8b6c7f2859939a75;';
$parsed_ini = parse_ini_string($ini);
echo $parsed_ini['com'];

I have a variable $TYPE=K180M-2
I need to "extract only the part until the dash (K180M) in a new variable.
How can I do it?
You may try:
$arr=explode("-", $TYPE);
$arr[0] will give you the desired result.
<?php
$newType = substr($TYPE, 0, stripos($TYPE, '-'));
?>
Will work.
You can use explode :
<?php
$K180M = '45';
$TYPE = 'K180M-2';
$var = explode('-',$TYPE,2);
$$var[0]; // this is your new variable named $K180M
var_dump($$var[0]); // result 45
If you prefer a regular expression, use preg_replace()
// Delete the dash and anything following it:
$type_without_dash = preg_replace("/-.*/", "", $TYPE);
Simply use
$value=strstr($TYPE,'-',TRUE);

Hi all i am looking for a simple way to check if a string equals an url like this:
http://youtu.be/WWQZ046NeUA
To convert it to a proper youtube url like this:
http://www.youtube.com/watch?v=WWQZ046NeUA
If not to leave it alone, what's the simplest way to do it in php?
You can use this preg_replace call:
$u = 'http://youtu.be/WWQZ046NeUA';
$r = preg_replace('~^https?://youtu\.be/([a-z\d]+)$~i', 'http://www.youtube.com/watch?v=$1', $u);
str_replace should work wonders.
$url = ''; //url you're checking
$ytshorturl = 'youtu.be/';
$ytlongurl = 'www.youtube.com/watch?v=';
if (strpos($url,$yturl) !== false) {
$url = str_replace($ytshorturl, $ytlongurl, $url);
}

I have a string input using PHP that look like this:
Log,,t1,12.12:t2,20.23:t3,30.00:t4,50.20:11.23
I want to save it into MySQL
field:reading
t1:12.12
t2:20.23
t3:30.00
t4:50.20
Temp:11.23
Can anyone give me an direction?
Begin you have to parse to rows and columns
$string = 't1,12.12:t2,20.23:t3,30.00:t4,50.20:11.23';
$rows = explode(':', $string);
$table = array();
foreach(rows as $row) {
$table[] = explode(',', $row);
}
You can use regex below:
if (preg_match_all('/[a-z]+\d+,\d+\.\d+|\d+\.\d+/i', $string, $matches) {
var_dump($matches[0]);
}
The regex can be a bit simpler if each field will called "t+number":
if (preg_match_all('/t\d+,\d+\.\d+|\d+\.\d+/i', $string, $matches) {
var_dump($matches[0]);
}

I want to remove a particular match of characters from a string.
For example i have strings;
topics-p10-new-model-cars
topics-p20-new-model-cars
topics-p30-new-model-cars
topics-p40-new-model-cars
Then i need the results as,
topics-new-model-cars
topics-new-model-cars
topics-new-model-cars
topics-new-model-cars
That means i want to remove p10-,p20-,etc..
.Those are the page numbers. It may be any number..
How can i do this..? Thanks in advance
Try this:
$result = preg_replace('/\-p\d+/', '', $string);
Note: I'm assuming that the string format does not change (I mean this [topics-p10-new-model-cars]). If my assumption is right.
Then you can do this
if (textBox1.Text.Contains("-p10-"))
{
//topics-p10-new-model-cars
String[] splited = textBox1.Text.Split(new char[] {'-'});
String rString = String.Format("{0}-{1}-{2}-{3}",
splited[0],splited[2],splited[3],splited[4]);
MessageBox.Show(rString);
}
//OR This method
if (textBox1.Text.Contains("-p10-"))
{
String result = textBox1.Text.Replace("p10-", "");
MessageBox.Show(result);
}
With 'preg-replace'::
For, example:
<?
echo preg_replace('/p[0-9]+\-/', '', 'topics-p10-new-model-cars');
?>

I have a string : http://www.mywebsite/456754567/531613490.htm?menu=contact
I want to get the value between "/" and ".htm". Here : 531613490
Any idea ?
if ( preg_match('~[^/]+(?=\.htm)~', $string, $matches) ) {
echo $matches[0];
}
Here's a demo: http://codepad.viper-7.com/5kjEj6
I don't know how flexible you want your script to be, but here's my try:
It always takes the last part of the path
It won't fail for http://www.mywebsite/456754567.htm/531613490.htm?menu=contact' as Joseph Silber's solution does.
<?php
$path = parse_url('http://www.mywebsite/456754567/531613490.htm?menu=contact', PHP_URL_PATH);
$pathParts = explode('/', $path);
$fullFilename = array_pop($pathParts);
// better use something like lastIndexOf(), this won't fail for 'xxx.abc.htm'
$filename = substr($fullFilename, 0, strpos($fullFilename, '.'));
var_dump( $filename );
