Run the function in all parts of the php line

Question

I built a function that will capture text between brackets and output them as an array. But the problem is that my function is only executed for the first time in a string.

function GetBetween($content,$start,$end){ $r = explode($start, $content); if (isset($r[1])){ $r = explode($end, $r[1]); return $r[0]; } return ''; } function srthhcdf($string){ $innerCode = GetBetween($string, '[coupon]', '[/coupon]'); $iat = explode('&&', $innerCode); $string = str_replace('[coupon]','',$string); $string = str_replace('[/coupon]','',$string); $newtext = '<b>'.$iat[0].'</b> <i>'.$iat[1].'</i><b>'.$iat[2].'</b>'; $string = str_replace($innerCode,$newtext,$string); return $string; } $Text = srthhcdf($Text); 

But it matches only the first [coupon] and [/ coupon] not the others. For example, when the line

 hello world [coupon]hello && bad && world[/coupon] and also to [coupon] the && bad && world [/coupon] 

He outputs

 Hello world <b>hello </b> <i> bad </i><b> world</b> and also to the && bad && world. 

This means that every time it replaces [coupon] and [/coupon] , but does not format the text inside them every time.

Check out my solution. Your problem is that you replace the codes after the first call, and there is no loop:

 function GetBetween($content, $start, $end) { $pieces = explode($start, $content); $inners = array(); foreach ($pieces as $piece) { if (strpos($piece, $end) !== false) { $r = explode($end, $piece); $inners[] = $r[0]; } } return $inners; } function srthhcdf($string) { $innerCodes = GetBetween($string, '[coupon]', '[/coupon]'); $string = str_replace(array('[coupon]', '[/coupon]'), '', $string); foreach ($innerCodes as $innerCode) { $iat = explode('&&', $innerCode); $newtext = '<b>' . $iat[0] . '</b> <i>' . $iat[1] . '</i><b>' . $iat[2] . '</b>'; $string = str_replace($innerCode, $newtext, $string); } return $string; } $testString = "hello world [coupon]hello && bad && world[/coupon] and also to [coupon] the && bad && world [/coupon]"; $Text = srthhcdf($testString); echo $Text; 

Answer 2

using regex will be an easy solution for this kind of thing

 $Text = "hello world [coupon]hello && bad && world[/coupon] and also to [coupon] the && bad && world [/coupon]"; $result = preg_replace('%\[coupon]([^[]*)\[/coupon]%', '<i>\1</i>', $Text); print $result; 

Answer 3

Try using this code:

 $Text = 'hello world [coupon]hello && bad && world[/coupon] and also to [coupon] the && bad && world [/coupon]'; echo preg_replace('#\[coupon\][\s]*(\w+)([\s&]+)(\w+)([\s&]+)(\w+)[\s]*\[\/coupon\]#i', '<b>$1</b> <i>$3</i><b>$5</b>', $Text); 

Answer 4

Solution with ReGex (captures all text and [coupon] [/ coupon] and replaces them with a new line

 preg_replace('#\[coupon\][A-Z0-9]+\[/coupon\]#i', $replaceText, $content); 

if you want to save the [coupon] tags:

 preg_replace('#(\[coupon\])[A-Z0-9]+(\[/coupon\])#i', '$1'.$replaceText.'$2', $content);
