As the answers here demonstrates nicely  yes  there are several ways  However  in PHP you rarely actually need to do that  The  dogmatic way  to write PHP is to rely on the language s loose typing system  which will transparently coerce the type as needed  For integer values  this is usually without trouble  You should be very careful with floating point values  though

foo   5    foo    foo         Now  foo is a string   But  you may want to get used to casting  As casting is the proper way to accomplish something of that sort    foo   5   foo    string  foo    Another way is to encapsulate in quotes    foo   5   foo     foo

You can use the strval   function to convert a number to a string  From a maintenance perspective its obvious what you are trying to do rather than some of the other more esoteric answers   Of course  it depends on your context   var   5      Inline variable parsing echo  quot I d like   var  waffles quot        I d like 5 waffles     String concatenation  echo  quot I d like  quot   var  quot  waffles quot      I d like 5 waffles     The two examples above have the same end value           And so do the two below     Explicit cast   items    string  var      items      quot 5 quot       Function call  items   strval  var       items      quot 5 quot

There are a number of ways to  convert  an integer to a string in PHP   The traditional computer science way would be to cast the variable as a string    int   5   int as string    string   int  echo  int     is a    gettype  int      n   echo  int as string     is a     gettype  int as string      n     You could also take advantage of PHP s implicit type conversion and string interpolation    int   5  echo  int     is a    gettype  int      n     int as string     int   echo  int as string     is a     gettype  int as string      n     string int    int     echo  int as string     is a     gettype  int as string      n     Finally  similar to the above  any function that accepts and returns a string could be used to convert and integer  Consider the following    int   5  echo  int     is a    gettype  int      n     int as string   trim  int   echo  int as string     is a     gettype  int as string      n     I wouldn t recommend the final option  but I ve seen code in the wild that relied on this behavior  so thought I d pass it along

User · Answer

I would say it depends on the context  strval   or the casting operator  string  could be used  However  in most cases PHP will decide what s good for you if  for example  you use it with echo or printf     One small note  die   needs a string and won t show any int
