PHP String searching

[jk11uk]

Hi

 

i have a php script that takes a url and loads all the code from that page into a variable.

 

I then want to scan through that variable and pick out the first 5 URLs. So i would need something which looks for the first 5 times that <a href="http://........someurl....."> happens and store the occurances into different variables.

 

 

can anyone work it out? i'm very stuck  ???

file_get_contents

then regex or strip tags without anchors

<?php
$file = "";
$data = file_get_content($file);
$data = strip_tags($data, "<a>");
$data = explode("<a",$data);
print_r($data);

Explode on <a will give you EVERYTHING before and after the next tag, which will include content from the page too..., which is NOT the result you are after. Use a regular expression instead.

it will explode each anchor so yes they will all need trimmming, but for those of us without regex this works out

i dont understand how that would work. so it strips the data of the <a  and </a> tags. but then the explode would not find any <a things to divide the string by, as you have stripped them?

 

Does anyone know the regex code that would do it?

preg_match_all('%<a\s.+?</a>%s', $data, $matches);
array_splice($matches[0], 5);
print_r($matches);
