De PHPhulp kroeg
Allowed memory size exhausted
Ik krijg ineens de foutmelding bij mijn resize script:
Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 13056 bytes) in resizeImage.php on line 53
Ik heb een beetje het web doorgezocht het script beken etc. Het vergroten van het memory lijkt me niet echt handig volgens mij is dat gewoon uitstellen van het probleem. Het bestand wat ik probeer te resizen is 1,75 mb. Dus dat lijkt me niet te groot. Ik heb ook nog even een kleinere van 800 kb geprobeerd maar dat lukte ook niet.

Nu vind ik het wel heel raar. Ik heb overal echo's tussen gezet zodat ik weet waar hij stopt. Maar nu doet hij het weer. Ik neem aan dat dit tijdelijk is want ik heb niets veranderd aan het script.
