Question

I'm using the code below for highlight one word from file_get_content and go to anchor.

$file='
IAR6=1002
SHF6=1
REF6=0002
TY7=2
DATE7=20130820182357
STAT_N7=1002
SEQ7=0002110000001
STA7=000005
TY8=2
DATE8=20130820182429
STAT_N8=1002
SH8=1
OP8=S123
SEQ8=0002120000081
';

$Seq = 0002110000001;
$text = preg_replace("/\b($Seq)\b/i", '<span class="highlight"><a name="here">\1</a></span>', $file);

for now this highlight : 0002110000001

i would like to highlight all part of the same index number.

ex: looking for 0002110000001

highlight this part of txt only where number is 7

TY7=2
DATE7=20130820182357
STAT_N7=1002
SEQ7=0002110000001
STA7=000005

Any help will be appreciated.

EDIT: i try to be more specific. file contain lot of code parts always start by TYx (x is auto numbering)

i have the SEQ number for my search , in ex 0002110000001 the preg_replace("/\\b($Seq)\\b/i", '\\1 find 0002110000001 and higlight them.

what i need is higlight what is between TY7 and TY8 instead of only 0002110000001.

Hope this is clear enough due to my bad english

thanks

You can make use of stripos() and explode() in PHP

<?php
$file='
IAR6=1002
SHF6=1
REF6=0002
TY7=2
DATE7=20130820182357
STAT_N7=1002
SEQ7=0002110000001
STA7=000005
TY8=2
DATE8=20130820182429
STAT_N8=1002
SH8=1
OP8=S123
SEQ8=0002120000081
';
//$Seq = "0002110000001";
$Seq = "7";
$new_arr=explode(PHP_EOL,$file);
foreach($new_arr as $k=>$v)
{
if(stripos($v,$Seq)!==false)
{
echo "$v\n";
}
}

OUTPUT :

TY7=2
DATE7=20130820182357
STAT_N7=1002
SEQ7=0002110000001
STA7=000005
