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 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 can find many examples of finding URL's withing HTML, however, I need to be more specific and extract the URL for the image in the following piece of text:
I will only need the first match.
I am using PHP.
Expected value result: http://cdn.somewebsite.com/path/123.jpg
var flashvars = {
'url_mode':'1',
'image':'http://cdn.somewebsite.com/path/123.jpg',
'bufferlength':'3',
'id': 'player',
'autostart': 'true'
...
};
Using preg_match with positive lookbehind assertion:
$data = <<< EOF
var flashvars = {
'url_mode':'1',
'image':'http://cdn.somewebsite.com/path/123.jpg',
'bufferlength':'3',
'id': 'player',
'autostart': 'true'
...
};
EOF;
preg_match("/(?<='image':')[^']+/", $data, $match);
echo($match[0]);
Hi this should work for you.
preg_match(/http.*?\.jpg/)

I'm a newbie with PCRE in PHP. I'm trying to make a very basic shortcode function that could make something with a format like this one: {somealphanumericthing}
In essence I need a preg_match_all() that could find in my post these type of occurrences. I tried something like this:
$shortcode = preg_match_all('/^\b\{[a-zA-Z0-9_]+(\}\b)$/', $body, $found);
var_dump($shortcode);
if($shortcode==1) {
for($i=0;$i<count($found);$i++) {
print_r($found);
//do something nice
}
}
But unfortunately it's not working: I get int 0 to the test string {test}
A few things about the regular expression:
You don't need your line anchors since you are searching in a larger string.
There's not need to capture the closing }
Optimization, use the character class \w
Condensed:
/\b\{[a-zA-Z0-9_]+\}\b/

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'];
