PHP - Finding Occurrence Of Values In A String.

Folks,

I want to find a Word in a string. If the word is found, i want to retrun TRUE else FALSE.

$string: Sol 3 Drawer Chests Antique Pine Bedside Chest

$word to be found: Chest

Now the tricky part is: In the $string the $word occurs twice once its CHESTS (i mean the first occurance) then CHEST.

If its found, i want to return TRUE else FALSE.

I tried using strpos() but it just checks for CHEST and not CHESTS.

How can it be achieved?

Cheers
Natasha

I have a simple db with values.

I want to find all duplicate values and rename them 1,2,3 - so if I have these values for a 'colour' field:

pID / color

1 / brown
2 / blue
3 / red
4 / red
5 / brown

...would result in:

1 / brown1
2 / blue
3 / red1
4 / red2
5 / brown2

...is this possible?

%3$s displays a string of text that always begins with a number followed by a colon (from 1-25 only).

1:
2:
3:
etc...

Is there a way to remove the number and the colon entirely and leave the rest of the string intact?

Code: [Select]
function wp_rss( $url, $num_items = -1 ) {
if ( $rss = fetch_rss( $url ) ) {

if ( $num_items !== -1 ) {
$rss->items = array_slice( $rss->items, 0, $num_items );
}
//start count
$i = 1;
foreach ( (array) $rss->items as $item ) {
printf(
'<div title="%2$s"><strong>'.$i.'</strong></div><div>%3$s</div>',
esc_url( $item['link'] ),
esc_attr( strip_tags( $item['description'] ) ),
htmlentities( $item['title'] )
);
//increment
$i++;
}

This topic has been moved quickly to PHP Regex because I need to go to work instead of lurking phpfreaks.

Hello,

I need to be able to find what is inbetween 2 values in a string of text.

For example,

<?php
$string="Hello and welcome to the site. Click [link]welcome.php[/link] here to continue to the site";

?>

So I need some method of searching the string to see what values are in between the [link] and [/link] which I will then deal with in my own way.

I have a feeling that I could do this with explode, but I'm not really sure. Any advice?

Thanks in advance

Hi, and thanks for any help with this. 

I have this but of php i have been trying relentlessly to get working.. for over a month.
 

<?php
$abs="one two three four words";
$mT = "testing for matching words";

$words=explode(' ', $abs);
//$sf=($words);


if (preg_match($words, $mT))
{
        echo "the url $mT contains a Word";
}
else
{
        echo "the url $mT does Not contain a Word";

echo "$words[4]";

}
?>

You see, I get a responce only using the last line "$words[4]", (obviously, because I am pointing it the Matching word, (ie: with [4])
What i need to have is that the script will automatically "find" that Matching Word for me with ANYwhere of the string of $abs (not just the beginning or the ending)". 

not making it confusing, but the obvious word in this I am looking to find is the word, "words".
😕

Thanks so much for any help.

better description.

Hi,

I have a string with the value of

{ "success": true, "delivered": true, "contactDetailsRequired": false, "message": "Signed For by: D ANDERSON ", "signature": "https://webservices.thedx.co.uk/PodImage/ImageHandler.ashx?tn=906732192165", "date": "21-07-2020", "serviceLevelName": "Consigned", "time": "13:33:19", "trackedProductName": "DataExchange" }

How do i go about placing the values into variables so for example:

$success = "true";
$delivered = "true";
$message = "Signed for by: D ANDERSON";
etc....

My mind has gone blank and im having one of those days, any help would be greatly appreciated. Thanks

Hi,

I currently have a string with some values in it:

$a_random_string="some random text, goes here - $123<br>some more random text goes here - $53 (text 123 )<br>ANother line of text - $126";

Now I want to add all the values that have a '$' before the value eg; $123.

So in this case I would end up with: 302

How would I do this?

Thanks,

mme

Pretty basic question here,

I have a string called:

$string

I want to use a php replace function or whatever would be best to find the first occurence of ] and for the string to delete from ] And everything after that first occurence of ] In the string.

Example

$string = "Hello Friends [Test] My name is John";

After the php function

$string "Hello Friends [Test";

I have this form

<form action="" method="get" name="size"> Størrelse <hr><label><input type="radio" value="9" name="size" onchange="this.form.submit()">92 (2år)</label>


<label><input type="checkbox" value="147" name="size" onchange="this.form.submit()">68 (6-9 mdr.)
</label><label><input type="checkbox" value="150" name="size" onchange="this.form.submit()">86 (18-24 mdr.)</label>
<input type="checkbox" value="149" name="size" onchange="this.form.submit()">80 (12-18 mdr.)</label>
<label><input type="checkbox" value="148" name="size" onchange="this.form.submit()">74 (9-12 mdr.)</label>


</form>

I want to make it so that when the user clicks one checkbox for example size 68 and then checks size 80 I want both sizes to be in the URL query string. But every time the user clicks a new checkbox, the query string changes accordingly. Maybe with a separator like ?size=4:23 and then I will handle it with the DB stuff.   Please tell me how to add multiple elements in the query string with this form, thank you!

Hi all, i've got a string ($currentcatid) which contains one number which changes dependant on which page the visitor is on.. ie  it may be perhaps "23" or "17" .

I need to do a check against this string to see if it contains any of the following values .. 31,32, 1, 24 . I cant remember how i did it before but i think it was with pipes..

something along the lines of
if ($currentcatid =="31"||"32"||"1"||"24") { action }

can anyone help?

Thanks

okay all i need is a way to make 4 <OPTION> values into a string which i can compare to a row in my db.

 This is my form.
Code: [Select]
<select name='n1'>
        <option value='0'>0</option>
        <option value='1'>1</option>
        <option value='2'>2</option>
        <option value='3'>3</option>
        <option value='4'>4</option>
        <option value='5'>5</option>
        <option value='6'>6</option>
        <option value='7'>7</option>
        <option value='8'>8</option>
        <option value='9'>9</option>
    </select>
    <select name='n2'>
        <option value='0'>0</option>
        <option value='1'>1</option>
        <option value='2'>2</option>
        <option value='3'>3</option>
        <option value='4'>4</option>
        <option value='5'>5</option>
        <option value='6'>6</option>
        <option value='7'>7</option>
        <option value='8'>8</option>
        <option value='9'>9</option>
    </select>
    <select name='n3'>
        <option value='0'>0</option>
        <option value='1'>1</option>
        <option value='2'>2</option>
        <option value='3'>3</option>
        <option value='4'>4</option>
        <option value='5'>5</option>
        <option value='6'>6</option>
        <option value='7'>7</option>
        <option value='8'>8</option>
        <option value='9'>9</option>
    </select>
    <select name='n4'>
        <option value='0'>0</option>
        <option value='1'>1</option>
        <option value='2'>2</option>
        <option value='3'>3</option>
        <option value='4'>4</option>
        <option value='5'>5</option>
        <option value='6'>6</option>
        <option value='7'>7</option>
        <option value='8'>8</option>
        <option value='9'>9</option>
    </select>

here is the php code which i tried but doesnt seem to work.
Code: [Select]
       $n1 = $_POST['n1'];
       $n2 = $_POST['n2'];
       $n3 = $_POST['n3'];
       $n4 = $_POST['n4'];
       
       $string = ("" . $n1 . "" . $n2 . "" . $n3 . "" . $n4 . "");

echoing $string does give to correct numbers.. but when i try and compare it to my database it doesnt match.


all help would be great.

Say you have a string that you know has two, and exactly two, periods in it, like this...

$string = "3.12.8"

How can you grab the three different values that are separated by periods (in this case, 3, 12 and ?   I was thinking use strpos to find the position of the first period, then could use that info to grab everything up to that position.  But then I couldn't figure out how you would find the position of the SECOND period.   And even if I could get the exact positions of the two periods, it seems like there should be an easier way to simply retrieve values separated by specific characters.     Is there a specific function for this type of thing, or was my initial though correct with having to do it in two parts essentially (find positions of periods, then use that knowledge to get the values)?   Thanks!

I am trying to make it echo if a string doesn't equal any of the values.   I have tried:   if(!preg_match("/none|Blue|Brown|Green|Grey)/i", $eyecolor)){ echo "Not an eye color"; } 

Hey there...
