Preg_split - Php Help Required

[alan_g]

Hi,

 

We have a number of strings, which take on the basic format of fieldname followed by value. Each fieldname always starts with {$ and ends with $}. The fieldname is always made up of alphanumerics and spaces. I need to split the strings by the fieldname, so I have two componets 1. Fieldname 2. Value

 

e.g. strings are:

 

string: {$begin Take$} My story began

string: {$a publication$} The daily newspaper

string: {$ date of creation$} 04/06/2007

 

- so I would then have the parsed data as:

fieldname:{$begin Take} value:My story began

fieldname:{$a publication} value:The daily newspaper

fieldname:{$ date of creation$} value:04/06/2007

 

We're doing this parsing in PHP and need the code/ help with the preg_split for this.

All help very much appreciated

Not sure if preg_split can be used for double splitting like that. If each string is seperate you could loop through them.

 

The regex would be something like '!(\{\$\w\$\}) (.+)!' or something similar.

I don't know if this is the best way to do it or not, but this should work:

 

list( $fieldname, $value ) = preg_split( '/(\\{\\$.+\\$\\})/', $string, 2, PREG_SPLIT_NO_EMPTY | PREG_SPLIT_DELIM_CAPTURE );
