There is a code:

<?php $a = '<div style="text-align:center;"><!--image_begin:https://dl.site.com/20/NTQ3Nw==/Fists.jpg|--></div>'; preg_match('/image\_begin\:(.+)\|\-\-\>/', $a, $b); print_r($b); Array ( [0] => image_begin:https://dl.site.com/20/NTQ3Nw==/Fists.jpg|--> [1] => https://dl.site.com/20/NTQ3Nw==/Fists.jpg )

How to get rid of [0] => image_begin:https://dl.site.com/20/NTQ3Nw==/Fists.jpg|--> ?

That is, as a result, only the URL of the search image is displayed as the only element of the array. I am a regular no expert on this appeal to you.

Try to write more detailed questions. To get an answer, explain what exactly you see the problem, how to reproduce it, what you want to get as a result, etc. Give an example that clearly demonstrates the problem. If the question can be reformulated according to the rules set out in the certificate , edit it .

  • You can get rid of and not being a connoisseur of regulars: unset($b[0]) . In general, the first element corresponding to the entire template is the normal behavior of preg_match . - Yegor Banin
  • @EgorBanin I’m talking about the means of the preg_match function, without the subsequent formatting of the array. - Ivan
  • You can use affirmations ( php.net/manual/ru/regexp.reference.assertions.php ) and not use exciting subtitles: (?<=image_begin\:).+(?=\|-->) . - Yegor Banin

How to get rid of [0] => image_begin: https://dl.site.com/20/NTQ3Nw==/Fists.jpg|-- >?

You can use retrospective and advanced checks - they do not capture characters that participate in matches:

 $a = '<div style="text-align:center;"><!--image_begin:https://dl.site.com/20/NTQ3Nw==/Fists.jpg|--></div>'; preg_match('~(?<=_begin:).+?(?=\|-->)~', $a, $b); var_dump($b);

Result:

 array (size=1) 0 => string 'https://dl.site.com/20/NTQ3Nw==/Fists.jpg' (length=41)

    http://php.net/manual/ru/function.preg-match.php read about the function. Regularity itself is nothing to do with If you want another array. Create it from $ b [1]
