You may as well use substr and strpos for this.

<pre><code>$startsAt = strpos($out, "{FINDME}") + strlen("{FINDME}");
$endsAt = strpos($out, "{/FINDME}", $startsAt);
$result = substr($out, $startsAt, $endsAt - $startsAt);
</code></pre>

You'll need to add error checking to handle the case where it doesn't FINDME.

I love these two solutions

<pre><code>function GetBetween($content,$start,$end)
{
 $r = explode($start, $content);
 if (isset($r[1])){
 $r = explode($end, $r[1]);
 return $r[0];
 }
 return '';
}


function get_string_between($string, $start, $end){
 $string = " ".$string;
 $ini = strpos($string,$start);
 if ($ini == 0) return "";
 $ini += strlen($start); 
 $len = strpos($string,$end,$ini) - $ini;
 return substr($string,$ini,$len);
}
</code></pre>

I also made few benchmarks as well with both solutions above and both are giving almost the same time. You can test it as well. I gave both functions a file to read which had about 60000 characters (reviewed with Ms. Word's word count) and both functions resulted in about 0.000999 seconds to find.

<pre><code>$startTime = microtime(true);
GetBetween($str, '&lt;start&gt;', '&lt;end&gt;');
echo "Explodin Function took: ".(microtime(true) - $startTime) . " to finish&lt;br /&gt;";

$startTime = microtime(true);
get_string_between($str, '&lt;start&gt;', '&lt;end&gt;');
echo "Subsring Function took: ".(microtime(true) - $startTime) . " to finish&lt;br /&gt;";

blocks|key|1450674|text|这是一个PHP解决方案，它返回在干草堆中的标记之间找到的字符串。它可以工作，但是我还没有测试它的效率。我需要这个，这一页上Adam+Wright的回答给了我灵感。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1450675|返回一个数组()，其中包含在$haystack中找到的$tag和$end_symbold.$tag之间的所有字符串，如果未找到$end_symbol.$tag，则返回FALSE，因此$haystack中不存在标记对。|1450676|function+str_between_tags($haystack,+$tag,+$end_symbol){

This is a PHP solution that returns the strings found between tags in a haystack. It works, but I haven't tested for efficiency. I needed this and was inspired by Adam Wright's answer on this page.

Returns an array() containing all the strings found between $tag and $end_symbold.$tag in $haystack, or FALSE if no $end_symbol.$tag was found hence no tag pair exists in the $haystack.

<pre><code>function str_between_tags($haystack, $tag, $end_symbol){
 $c_end_tags = substr_count($haystack, $end_symbol.$tag);
 if(!$c_end_tags) return FALSE;

 for($i=0; $i&lt;$c_end_tags; $i++){
 $p_s = strpos($haystack, $tag, (($p_e)?$p_e+strlen($end_symbol.$tag):NULL) ) + strlen($tag );
 $p_e = strpos($haystack, $end_symbol.$tag, $p_s);
 $result[] = substr($haystack, $p_s, $p_e - $p_s);
 }
 return $result;
}
</code></pre>

blocks|key|1236001|text|如果可能的话，我喜欢避免使用正则表达式，这里有一个替代的解决方案来获取两个字符串之间的所有字符串并返回一个数组。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1236002|function+getBetween($content,+$start,+$end)+{

print_r(getBetween("The+quick+brown+{{fox}}+jumps+over+the+lazy+{{dog}}",+"{{",+"}}"));|code-block|syntax|javascript|1236003|结果：|1236004|Array

I like to avoid using regex if possible, here is alternative solution to fetch all strings between two strings and returns an array.

<pre><code>function getBetween($content, $start, $end) {
 $n = explode($start, $content);
 $result = Array();
 foreach ($n as $val) {
 $pos = strpos($val, $end);
 if ($pos !== false) {
 $result[] = substr($val, 0, $pos);
 }
 }
 return $result;
}
print_r(getBetween("The quick brown {{fox}} jumps over the lazy {{dog}}", "{{", "}}"));
</code></pre>

Results :

<pre><code>Array
(
 [0] =&gt; fox
 [1] =&gt; dog
)
</code></pre>

Whats is the best way to obtain the content between two strings e.g.

<pre><code>ob_start();
include('externalfile.html'); ## see below
$out = ob_get_contents();
ob_end_clean();

preg_match('/{FINDME}(.|\n*)+{\/FINDME}/',$out,$matches);
$match = $matches[0];

echo $match;

## I have used .|\n* as it needs to check for new lines. Is this correct?

## externalfile.html

{FINDME}
Text Here
{/FINDME}
</code></pre>

For some reason this appears to work on one place in my code and not another. Am I going about this in the right way? Or is there a better way?

Also is output buffer the way to do this or file_get_contents?

Thanks in advance!
