zzyzh pro expansion is also true W)

  • no, guys, you didn’t understand me ... after .jpg there are more ~ ​​3000 sigmols and they always have a different number, I need to cut off exactly by the line entry - igolka97
  • Well? returns the string cut to the first occurrence of .jpg , if you use strrpos , then by the last entry ... read the description of the functions though ... or specify the question, at the moment our options correspond to your task. - thunder
  • @thunder Thank you very much everything works)) - igolka97
 substr($string, $from, $count);

  • @thunder I need a search for a string entry and not a character count ( - igolka97

And what prevents to find an index with the help of strpos / strrpos , and take a substring?

 substr($i, 0, strrpos($i, $y))

For PHP versions less than 5, you need a cycle, see the @thunder comment:

 $pos = 0; $found = false; do { $newpos = strpos($i, $y, $pos); if ($newpos !== false) { $pos = $newpos; $found = true; } } while ($newpos !== false); if ($found) $i = substr($i, 0, $pos); else ...
  • suppose I need to cut .jpg into the distilleryimage10.instagram.com/… HOW? - igolka97

    @VladD may not roll, since> 5.0.0 depends on the version of the PCP. 5.0.0 > 5.0.0 The offset parameter was introduced. - thunder
