String to array

[matfish]

Hi there,

 

I have HTML code which I then strip_tag just to get plain text into $text variable. The text looks like:

 

$text = "This paragraph references to [code: ref1, ref3, ref87] and the next bit references to [code: ref9, ref4]. There could be several references like [code: ref67, ref55]."

 

I want to put all those code: ref numbers into an array?

I tried something, but after it wrote the first ref numbers to an array it quit and does not look at the rest?

 

Any ideas would be appreciated.

I tried something, but after it wrote the first ref numbers to an array it quit and does not look at the rest?

i also tried something, but after i write the first couple of lines, it quit, and did not report a correct answer..... 

 

But...., i tried again:

<?php

$text = "This paragraph references to [code: ref1, ref3, ref87] and the next bit references to [code: ref9, ref4]. There could be several references like [code: ref67, ref55].";

$s=preg_split("/\[code:/", $text);

echo $text."<hr>";

print_r($s);

print "<hr>";
for ($f=0; $f<count($s); $f++) {
        print "$f: $s[$f] <br>\n";
}

print "<hr>";
$ref="";
for ($f=1; $f<count($s); $f++) {
        $t=substr($s[$f],0,strpos($s[$f],']'));
        $ref=$ref.$t.',';
        print "$f: $t <br>\n";
}

$b=explode(",",$ref);
print "<hr>";
for ($f=0; $f<count($b); $f++) {
        print "$f: $b[$f]   <br>\n";
}
?>
