how do i skip the 1st instance of a tag in the following code but pick up the2nd

[scbookz]

$osctag = preg_match_all('/<img src="images\/(.*).jpg/', $oscfile, $oscmatches, PREG_PATTERN_ORDER);

 

 

my 1st      <img src="images

  is the wrong  one  but the 2nd one on the page is right

 

how can i skip the very 1st one everytime in this code?

[Daniel0]

Use the $offset argument.

 

preg_match_all

[scbookz]

maybe i didnt make myself clear when i grab from the html page there are 2 different .jpgs

 

the 1st jpg is not  the one i want  in the process of reading the html page

the 2nd one is what i do want

 

my description is picking up the  1st and not the 2nd one as i like for it to do

[scbookz]

ohhhhhhhh  offset  so far  but how do i use offset lol

[scbookz]

everytime i tried offset it never worked does it have to be 8 16 32 64 etc etc

 

does it have to match some particular data for an offset?

 

because wheni tried 2 or 3  or weird number never worked

[Daniel0]

On second thought, $offset might not be so good for this. preg_match_all() will give you all the matches though, so you can just select the second one and ignore the first one.

[scbookz]

what in the same h does this allmean makes no sense to me

 

PREG_OFFSET_CAPTURE

 

    If this flag is passed, for every occurring match the appendant string offset will also be returned. Note that this changes the value of matches in an array where every element is an array consisting of the matched string at offset 0 and its string offset into subject at offset 1.

 

[scbookz]

here is my code how do i select the 2nd one please?

---------------------------------------------------

<?php

$oscfile = file_get_contents("http://75:81/osc/osc/osc/catalog/product_info.php?products_id");

$osc = (get_oscdoc_title($oscfile));

$test = $osc;

 

//function

function get_oscdoc_title($oscfile){

$osctag = preg_match_all('/<img src="images\/(.*).jpg/', $oscfile, $oscmatches, PREG_PATTERN_ORDER);

   

return($oscmatches[1][0]);}

echo $test;

$file = file_get_contents("http://www.bu.com/IsbnSearch.aspx?isbn={$test}");

$x = (get_doc_title($file));

echo preg_replace('/^Book -/','(10 digit isbn above) -',$x);

 

// retrieve page title

function get_doc_title($file){

    $h1tags = preg_match_all('/<title>(.*)<\/title>/', $file, $matches, PREG_PATTERN_ORDER);

return($matches[1][0]);}

 

?>

[scbookz]

do i get rid of  [0]  in  return($oscmatches[1][0]);}

[scbookz]

anyone    so you can just select the second one and ignore the first one.

 

how do you ignore the 1st one in the code?

[phpSensei]

$matches is an ARRAY!

 

If thats what we are talking about here cause i didnt read, just read Daniel0's post.

Array(

[0] => "1.jpg"
[1] =>  "2.jpg"

)

 

youw would be wanting the 2nd one $matches[1]

[scbookz]

i understand but my function is calling the  1st part  so how do i force it to see  the 2nd one only  and put it into my variable?

[scbookz]

i have 2 jpegs

<img src=x.jpg

<img src=y.jpg

 

i want the  2nd one in this function to show only

 

function get_oscdoc_title($oscfile){

$osctag = preg_match_all('/<img src="images\/(.*).jpg/', $oscfile, $oscmatches, PREG_PATTERN_ORDER);

   

return($oscmatches[1][0]);}

[phpSensei]

do print_r($oscmatches) and you'll see what i mean. its an array of matches it has found throughout the html.

[scbookz]

print_r($oscmatches) gave no output  but  printr test gave me the very 1st isbn  and printosc gave me 2 of the 1st

 

//function

function get_oscdoc_title($oscfile){

$osctag = preg_match_all('/<img src="images\/(.*).jpg/', $oscfile, $oscmatches, PREG_PATTERN_ORDER);

    return($oscmatches[1][0]);}

//echo $test;

print_r($oscmatches);

[scbookz]

oh i had to move printr before the function ended

thanks i see the array but now i need to know which one to call and how to do that

 

 

Array ( [0] => Array ( [0] =>  Array ( [0] => 0324183313 ) ) 0324183313(

 

its only showing  1  array value  instead of all the values on the page for that pattern

 

[scbookz]

where is my other  jpg  number

Array

(

    [0] => Array

        (

            [0] =>  Array

        (

            [0] => 1591167264

        )

 

)

 

it does not show both values on the page just one

[phpSensei]

your preg_match_all is wrong

 

try

 

preg_match_all('/<img[^>]*>/Ui',$oscfile,$oscmatches);

[scbookz]

even when i use that ist  does not solve problem of skipping down to another instance

 

i need to know how to start at a different location in a page

Preg_match_all goes through the entire match trying to find what you need, its not a matter of different locations, if it finds an img tag it stores it in its 3 argument which is an array of possible matches..
