How to extract part of a string in php

Question

I use preg_replace () for some string replacement.

$str = "<aa>Let find the stuff qwe in between <id>12345</id> these two previous brackets</h>";

$do = preg_match("/qwe(.*)12345/", $str, $matches);

which works fine and gives the following result

$ match [0] = qwe in between 12345
$ match [1] = in between 

but I use the same logic to extract from the next line.

<text>
  <src><![CDATA[<TEXTFORMAT LEADING="2"><P ALIGN="LEFT"><FONT FACE="Arial" SIZE="36" COLOR="#999999" LETTERSPACING="0" KERNING="0">r1 text 1  </FONT></P></TEXTFORMAT>]]></src>
  <width>45%</width>
  <height>12%</height>
  <left>30.416666666666668%</left>
  <top>3.0416666666666665%</top>
  <begin>2s</begin>
  <dur>10s</dur>
  <transIn>fadeIn</transIn>
  <transOut>fadeOut</transOut>
  <id>E2159292994B083ACA7ABC7799BBEF3F7198FFA2</id>
</text>

I want to extract a string from

r1text1

to

</id>

I have a regex:

preg_match('/r1text1(.*)</id\>/', $metadata], $matches); 

where $ metadata is the line above.

Matches

$ doesn’t return anything .... For some reason ... how can I do this? thanks in advance

Answer 1

If you want to extract text, you probably want to use preg_match. The following may work:

preg_match('#\<P[^\>]*\>\<FONT[^\>]*\>(.*\</id\>)#', $string, $matches)

, , $matches. <P>, <FONT> </id>, .

, , . , :)
